However, and its a big however. Similar to the Amiga the C64 had custom chips to do music and various graphics and things. You need a 40Hmz Machine or above to run the C64 at full speed. For the spectrum you need just 25Hmz. So as you can tell from this it is more complex to emulate a C64 (taking into consideration all its processors) than to emulator a speccy. Its the same principle as Emulating an Amiga as appose to a PC. The PC can be emulated quit quickly in retrospect to a PC or other machine emulating an Amiga. You see the Amiga has loads of custom co-processors working in unison with the 680x0 processor and these need to be emulated simultaneously. As stated in the 'thread' its only a BASIC emulator so no optimised Assembly routines have been used. ----------------------------------------------------------------------------- A1200, Viper 030 - 42.6 Mhz,50 Mhz FPU, 4 MB Fast RAM, 170 MB Hard Drive, SyQuest EZ135Mb Drive, External Drive, Power CD-ROM Drive, CD-32 __ /// Andrew Barker - ca4aba@osiris.sund.ac.uk __ /// Web Page - http://osiris.sund.ac.uk/~ca4aba/home.html \\\/// or /index.html \/// Amiga - Underestinamted ! ----------------------------------------------------------------------------- And A Lame PeeCee - P133, 16Mb, 1.1GB HD, 8xCD-ROM, 14" SVGA Monitor, 2Mb S3Trio 64V+ Graphics Card Still Lame ! ----------------------------------------------------------------------------- Article 36452 of comp.sys.sinclair: Path: news.ox.ac.uk!lyra.csx.cam.ac.uk!nntpfeed.doc.ic.ac.uk!sunsite.doc.ic.ac.uk!agate!howland.erols.net!newspump.sol.net!newsfeeds.sol.net!europa.clark.net!disgorge.news.demon.net!demon!dispatch.news.demon.net!demon!jetman.demon.co.uk!not-for-mail From: damien@jetman.d.c.u (Damien Burke) Newsgroups: comp.sys.sinclair Subject: Re: Spectrum Emulator for C64 Date: Tue, 20 May 1997 20:54:54 GMT Organization: Ha!

Emulators are no good for estimating the complexity of a machine because they are all different. Given that CCS64 requires a P133 I'd draw the conclusions that it's either 'written in C' or 'written very badly' rather than 'C64 is more complex than the Spectrum'. That said, it's blatantly obvious to anyone that the 64 hardware is much harder to emulate than the Spectrum's. Just not THAT hard.

Nowhere do I recall attempting to make any sort of comment on the quality, design, or usability of the Spectrum. In fact, I recall prefacing that post with a statement to the contrary.

At least the atari had installable device handlers (how do you use a RAM disk on a Commodore?,or a different,faster RS232 interface), 1D sector addressing rather than 3D (track,sector,side).

I know that it uses the stack all the time to comunicate with library routines even when the registers would be enough. Using DJGPP is good because it allocates memory like UNIX does. That is,memory is automaticly allocated (in 4k blocks) when the CPU accesses a (non-existent) memory location.Of course this depends on what DPMI/VCPI interface you are using.

Seeing as Quite the opposite. I simply put the question to you: is anything in my above statement erroneous? As I see it, it contains three main points, here outlined for the tunneled of vision: 1. Most Europeans used tape drives instead of disk drives. 2. A disk drive is much more flexible than a tape drive. 3. Some Europeans, yourself perhaps, often don't understand why a disk drive is more useful than a tape drive, perhaps because they've never had one, or used programs which take advantage of a disk drive. See point #1. As to the spurious nationalistic accusational sanctimony, I find that many people, when they have nothing really spectacular or witty to say, resort to attempting to change the subject with spurious nationalistic accusational sanctimony. The most elusive thing however is why some Europeans think that the USA views them all as ignorant peons, who when taken city by city have an aggregate I.Q. sufficient for shoe tying*. In point of fact, many people in the USA cannot even find Europe on a map, let alone care what Europeans are doing or thinking. I thus take such statements as statements of general insecurity, for reasons unknown. * Although it would explain Tony Blair ;-) ;-) >these 'European' tape drives (drive?) were faster than your 64's >disk drive, I don't think we missed out there, did we? I have no idea. As I have said, I have no experience with Spectrums. Tape drives on the 64 are certainly not as fast as disk drives on the 64 though, especially accelerated disk drives. Somehow, though, I thought my point was that a disk drive was much more flexible and useful than a tape drive.

Somehow you are able to imagine that some drastic comment about a Spectrum has been made, when in reality all that was made was a comment about a Commodore 64. What you fail to grasp is that I don't care about Spectrums. I have a wonderful machine that I am quite happy to use, and apparently unlike some other computer users its usefulness to me does not depend on how it compares with any other computer. Having said that, I have found these posts to be somewhat enlightening. As near as I can tell, a Spectrum is a Z80 with a simple graphics chip and a tape drive -- sounds more like a high school science project than a home computer. It has also reminded me about the flexibility of the 64 -- one of the reasons I enjoy it so much. The descriptions of the Spectrum have been terribly underwhelming and unflattering -- seems to me that there is one and only one way to accomplish a given task on the machine, and it is a brute-force method to boot. Since the Spectrum users seem to think games are the end-all comparison of computers, it got me to thinking. It got me to thinking about the kinds of games I used to play on the 64. As near as I can figure these games would be extremely difficult, if not impossible, to do on the Spectrum as described by its would-be advocates. These include role-playing games like Wasteland, Bard's Tale, and Ultima I-V. Raid on Bungeling Bay was awfully fun, as were many EA games like MULE, Archon I and II, Mail Order Monsters, Modem Wars, and many others. I also enjoyed the MicroProse simulations, like Silent Service, Gunship, etc. It boggles the mind to think about doing such games without the benefit of a disk drive, 64k, sprites, custom character sets, etc. (Maybe that's why the PC versions were so lousy). >>Somehow, though, I thought my point was that a disk drive was much more >>flexible and useful than a tape drive. Ah well... >> >Well or course it would! If i had a tape player that loaded a 40K >program in 10 minutes, and a disc drive that loaded the same game in 8.5 >mins, I would go for a disc drive. But at least the spectrum could load >a 128K game in under 6 minutes! Once again the seemingly elusive concept of an accelerated disk drive has slipped past another individual. Luckily Commodore drives are so flexible that not only can file transfers be sped up, but the disk encoding scheme can be abandoned entirely in favor of a new scheme. As a practical matter, this is manifested in two ways: first, the user can accelerate the disk drive, by adding a cartridge, replacing the ROM, or typing in any of the many fastloader programs published in magazines, etc. Second, any software company can include a fastloader as part of their program. In point of fact, nearly every major software company included fastloaders with their programs made after 1985 or so. None of which addresses the extreme flexibility which a disk drive gives over a tape drive. >>>And there was me thinking that was the 80x86 based PC. >> >>Well, that would explain why you are wrong. > >You stupid git! THat was a joke! At least we have a sense of humour. Ah, well, usually humor has a connotation involving wit, a clever turn of phrase, a thoughtful reference, an interesting analogy, an odd correlation, or a number of other facets. So you can see my confusion in your statement. I can see now that you are a man of rare wit indeed -- rare as in "not well-done". evetS- From starglider@thespian.demon.co.uk Wed Jun 4 16:53:16 CDT 1997 Article: 67957 of comp.sys.cbm Path: news.acns.nwu.edu!newsfeed.acns.nwu.edu!news.ece.nwu.edu!news.cse.psu.edu!uwm.edu!www.nntp.primenet.com!nntp.primenet.com!disgorge.news.demon.net!demon!dispatch.news.demon.net!demon!thespian.demon.co.uk!thespian.demon.co.uk!starglider From: The Starglider Newsgroups: comp.sys.sinclair,comp.sys.cbm,comp.emulators.cbm Subject: Re: Three if by network...

If a lot of Americans cannot find Europeans on a map, then how can we trust what they are talking about. That was the point I was making. As a little side-point here, a survey found a couple of years ago that 26% of Americans were convinced that the whole world was out to get them, and of that 26%, 75% of them owned guns. That tells me something about the mentality of the Americans. >>> > >The confusion stems on your part from something called "imagination". >Somehow you are able to imagine that some drastic comment about a >Spectrum has been made, when in reality all that was made was a >comment about a Commodore 64. > That's it exactly! Imagination! You see, the spectrum was built with some imagination. That's why the processor had soo much control over every aspect, so that the programmer could do anything the computer within the limits of the memory. The commodore was limited by the hardware. You cannot argue that point, so don't bother. >What you fail to grasp is that I don't care about Spectrums.

The spectrum DID do all that with no hardware sprites, disc drives etc... Jon Ritman (A highly respected programmer, who did classics like Head Over Heels, Batman, Matchday I and II) has even said that there were problems encountered in the same game played on a commodore compared to a spectrum. You see, I think the problem here is not that "The commodore had dedicated hardware to help do it's graphics quickly" which is true. Everyone knows that. But the CPU still does all the calculations and mathematics, and the spectrum was faster at that. Yet again, that's another point you cannot argue. The spectrum could (and did) deal with the graphics for all games, and compute all the neccesary maths for whatever it was doing, and STILL outrun the Commodore. Yet again, FACT. So don't argue that either (You're not going to have a lot to argue here, are you!). >Once again the seemingly elusive concept of an accelerated disk drive >has slipped past another individual.

You lot keep having to resort to the upgraded equipment. Why? The fact remained that with the standard non-upgraded C64 disc-drive was in slower than the spectrum cassette system. Fact. Spectrum also had speedloaders that loaded games at a baud rate of over 2500. That was faster than the C64's fastest loader. Fact. Every major software company HAD to include speedloaders in all their games. They took just too long to load.

This is down to those horrible limitations of hardware sprites that we keep mentioning. In an isometric game things not only have to go behind and in front of the background, but also between.

Okay take the fastest algorithm for producing a paritcular mathematical function. If you ran it on a Z80, which has more genral purpose registers, faster clock, bigger intstruction set it will run faster than the equivalent 6510 routine. That is just a plain fact.

And yet the humble Spectrum running a 3.5MHz Z80 can smoothly animate larger and more sprites than the C64 and its special hardware. I picked a number 6, which seemed reasonable to me with a 6510. It's a flexible number, but I think you overestimate the amount of computing power required to put up sprites on a screen of the C64's resolution. Or perhaps I overestimate the speed of the 6510? A Z80 at 3.5 MHz can put up sprites adequately enough on a Spectrum resolution screen. On a Commodore 64's, with higher colour resolution, it'd have to be a bit faster, but not much. > As a matter of fact, I happen to have a 20MHz 65816 in my 64 here. What > do you know, I can do processing _and_ let VIC handle sprites and such. > How is a fast processor + no VIC superior to a fast processor+VIC? If the 20MHz C64 were available ten years ago, and you were making games using the built in sprite hardware, your competition would bury you because their software sprites would put your games to shame. Yes, the hardware makes your task easier as a programmer, but you'd have inferior results. Now pretend you are the hardware manufacturer. You have a C64 at 1MHz with the special chips and a C64ish at 20MHz with no chips. Which is more cost effective given that the 20MHz C64ish machine can do better graphics? Now I ask you, why do you want special chips in your C64 20MHz machine? Games can only go so fast. You can only make so much use of the original 64's screen resolution. Perhaps it would be time to upgrade the display? My original point was that a 1MHz C64 + video hardware is not superior to another computer without video hardware. Faster processors can make up for the difference + more. > The value of dedicated graphics chips is self-evident by simply examining > e.g. an arcade game, an SGI Iris, a Playstation, etc. The whole point Dedicated hardware allows a designer to select slower CPUs which lead to a simpler motherboard = lower costs. Now tell me, with this special display hardware, what would you say the lifetime of these machines are? How long would a machine that allowed you to upgrade to a faster processor last? Or a better resolution? (IE- this is your IBM PC. They haven't changed all that much over the years). > is that you can use the processor for things like computations, instead > of managing the screen. Yes, which buys you a short term advantage over competitors for a period of time. Then the hardware becomes a liability when competitors can produce equivalent machines without the hardware (ie lower cost).

The C64 was made obsolete by the PC and other 16bit/32 bits that came out. The C64 survived in the low end 8bit market simply because the industry moved to 16bits and a higher cost bracket. The Spectrum was also a very successful computer with nearly 10 years of production. And the numbers would probably surprise you. > the video markets.

The only thing 680x series have in common with 65xx is that they're bus compatible. They're not even made by the same company! If it were a beefed up 65xx, then you would expect to see the same opcodes, same quirks, etc., and you simply don't. >And yet the humble Spectrum running a 3.5MHz Z80 can smoothly animate >larger and more sprites than the C64 and its special hardware. Hmm. Let's test this assertion. In front of me is a C128 in 64 mode with a raster hack designed to force the VIC-II to repaint its sprites four times from four sets of shadow sprite registers. 32 sprites and negligible loss in speed. I've seen people make 64 sprite hacks. Do 64 sprites on a software-based video system and I guarantee you'll see the performance hit from hell. >Or perhaps I overestimate the speed of the 6510? A Z80 at 3.5 MHz can put >up sprites adequately enough on a Spectrum resolution screen. On a >Commodore 64's, with higher colour resolution, it'd have to be a bit >faster, but not much. This shows how LITTLE you know about the 64's video architecture. Sprites on the 64 are a totally different videoplane. They aren't treated as part of the hires matrix at all as far as the machine is concerned. (Witness the fact that sprites are totally functional in 40x25 text mode, which I doubt is possible on the Spectrums.) >Now I ask you, why do you want special chips in your C64 20MHz machine? >Games can only go so fast.

How can you implement stuff like transparency, alpha-channel effects, MIP mapping, bi-/tri-linear filtering and all that good stuff with a faster and faster processor without wasting time on it? For the record, the 64 is totally upgradable. Didn't you read Stephen's point about the new SuperCPUs? Are you still going to claim that a 3.5MHz Spectrum with NO sidecar chips is going to wax a 20MHz, 16-bit C64 with an impressive list of dedicated hardware? Are you still going to claim that the 64's power has topped out? More importantly, the premise you're arguing under is 100% flawed. The argument that faster processors beat out dedicated hardware is flat out wrong. Want proof? The fastest computer in the world is not a Cray, it's a low-speed parallel processor unit used for calculating n-body problems. This unit, created by a Japanese astronomer and whimsically named GRAPE, uses a dedicated chip for one single calculation, which is gravimetric potential (as I recall). What the calculation is, isn't important. This machine is realizing petaFLOP speed without throwing brute force at the problem simply because it's always more efficient to make a dedicated solution than a versatile one. There's less code to go through. Read this article in Discover magazine (either the latest issue or the one before, I forget). Now you want to use the flexibility argument at me, right? Fine. You tell me one application that the Spectrum runs that the 64 with all its dedicated hardware does not. Don't name specific software packages at me because I don't know them. Tell me what type of software the Spectrum runs that the 64 doesn't, and I'm willing to bet I can prove you wrong. >> Keep in mind that the Commodore 64 had over a 10-year production run, and >> sold more units than any other single machine type.

And where did the Spectrum go? The Spectrum was just as obsolete and its market share sunk like cement. The 64 ruined many other 8-bit machines at the time, too. Where's the Acorn? The Exidy Sorceror? The CoCo? Heck, where's the MSXs?

I write software professionally for the 64 as a side business. Somehow I haven't found the need to upgrade. I suppose I'm abnormal, I guess.

If I remember correctly, the 6809 was designed first, then some engineers responsible for the 6809 left Motorola to form their own company and came out with the 6502. The fact that they're bus compatible indicates they certainly have a lot in common. I compared the 6502 to a 6809 a long time ago. The only differences were the 6809 had two 8 bit registers (rather than 1) that could be used as a single 16 bit register. Both were designed around the idea that registers could be emulated through fast access to RAM (page 0). Both had powerful addressing modes. The 6809 had some important advantages: two 16 bit index registers (rather than 8 bit) a 16 bit stack pointer (rather than 8 bit - v important IMO) The 6502 was intended to be a cheap, capable processor, but it wasn't intended to replace the 6809. If my memory isn't failing I also recall reading somewhere that Commodore selected the 6502 rather than the 6809 because of its price. The Z80 has a similar history; Zilog being formed by engineers leaving Intel. But the Z80 was an enhanced 8080 with hardware advantages. Out of curiosity, if someone can tell me, how similar are the instruction sets between the 6502 & 6809? Is there some binary compatibility? Are some instructions simply given different mnemonics? (In the Z80's case, it could run all 8080 software, with mnemonics changing names). > >And yet the humble Spectrum running a 3.5MHz Z80 can smoothly animate > >larger and more sprites than the C64 and its special hardware. > Hmm.

I've seen people make 64 sprite hacks. Do > 64 sprites on a software-based video system and I guarantee you'll > see the performance hit from hell. What are the sprite sizes & resolutions? What is the frame rate (sounds like your dropping the frame rate there - is there flicker?) I haven't seen more than 16 sprites on the screen at once at about 16x24 pixels on a Spectrum. I also can't imagine a game would use many more than that otherwise the screen would be full. There are a few things you can't argue away. 1. You can do sprites in software 2. The faster the CPU, the larger the sprites can become and the larger in number you can have. 3. There is a point where the C64's 6510 can be sped up to to emulate the C64's display hardware (I have no doubt Stephen's 20MHz 6510 can do it). 4. Other 8bit CPUs are faster than the 6510 and they were used in other machines without much display hardware. On those machines, sprites were done software and I'm arguing they did it as well as what the C64 did. The difference in appearance is due to different colour resolutions. Andy brought in the CPC - another Z80 based competitor in Europe with similar colour resolution of the C64. You can argue what resolution is better for games. Because of the hardware, the C64 has better colour resolution than the Spectrum. The Spectrum has better pixel resolution (you don't have a choice in the pixel dimensions of a C64 sprite and I'm also arguing the C64 isn't quick enough to do larger sprites in software). Because of the faster CPU in the Spectrum, it could do games that can't be boiled down to a finite number of sprites better than the C64 (Command Carrier is done in shaded 3d on the Spectrum, but in 2d overhead view on the C64). The C64 has a powerful sound chip. The UK 48k Spectrum had a beeper. The US 48k Spectrum had the AY chip (also used in the CPC, Atari ST, 128k Spectrum, etc.) The SID = AY + ability to put distinct envelopes on all channels rather than just one. Also has LP/BP filtering. There are probably a few more differences that aren't coming to mind right now. Both had great music written for them. On my US 48k Spectrum, I can play .wav, .au, etc. in mono at rates between 1 and 55kHz and in stereo at between 1 and 23kHz (4 bit samples). That's a testament to the processor's speed, I believe. > This shows how LITTLE you know about the 64's video architecture. > Sprites on the 64 are a totally different videoplane.

My argument all along has been that it isn't a good idea to set sprite characteristics in hardware because sooner rather than later there will be a CPU available that can do better in software. At that point the hardware is obsolete. I am also arguing that there were CPUs available at that time that were fast enough to do the same thing in software, namely the Z80, 8080 and possibly the 6809. By designing special hardware, Commodore could select a CPU like the 6502 to run the machine. I am *not* knocking the 6502 (some of you seem a little sensitive) - it is an interesting processor in its own right, but it wasn't the fastest. > (Witness the fact that sprites are totally functional in > 40x25 text mode, which I doubt is possible on the Spectrums.) I think you've misunderstood what software sprites are. On the Spectrum, *everything* is drawn on the screen bitmap - sprites, text, circles, lines, whatever - there is no distinction. All these things can quite happily exist together. The process of moving a sprite is in simple terms, erase it by drawing what was underneath it, change coordinate, draw it again while saving what was underneath it. If the 1MHz 6502 were fast enough, the programmers could take advantage of the "hacked" video modes on the C64 and deliver some higher resolution graphics in their games. > >Now I ask you, why do you want special chips in your C64 20MHz machine? > >Games can only go so fast.

The fact that the 8 bit 3.5MHz Spectrum can put up at least 16 sprites on a 256x192 screen should leave you with little doubt that 486/66 can do it on a 320x200 or 640x400 or .. > >It is not a good idea to burn high level graphics support in hardware. > So I assume you won't be buying your PC a 3-D accelerator card?

There's less code to go through. This is speed realized through parallelization. In the same way RISC CPUs are faster than their clock rates indicate because they're doing ten things at once.

The size of the Spectrum's software base proves its market share was significant. The same can be said of the C64. Both were made obsolete by 16bits and 32bits.

Most people did and still do write software for original 1 mhz 64 and 1541. Others write for expanded machines but you will not find the megalomania to "upgrade" that is so pervasive on some other platforms. If these C64 users do have the upgrade-fever, they are most likely upgrading their PC machines to get faster speed for C64 emulation. :) Anyways, one benefit of the LCD-mindset was that software became incredibly efficient. Someone on the spectrum side was arguing about how crappy the C64 basic, et al., is/was... Fine :)... It was also fast, compact, and forced a number of users to learn efficient assembly coding. It has been argued that the C64 produced more efficient programmers than any other system. It is a real shame that the market place now favors the inefficient and dirty programmer.

Actually when it comes to bloated inefficient code, I can think we can lay the blame firmly at MS's door; Windows & VB has a lot to answer for. Most Speccy stuff was so tightly coded that only a few bytes (if any) were left over; I moved on from Sinclair BASIC to Z80, then onto an ST where I never bothered with anything besides pure 68000 until being forced to learn C.

Because the hardware is doing almost all the work still. I take it your talking about what Amiga owners called 'Virtual Sprites'. I did the same thing on a CPC+ once, which had 16*16*16 sprites. So you could get 16 on a line. However as I remember it the processor had to do a lot of work flicking between sprite positions.

Depends on your definition really. I mean speccy games didn't exactly overflow with colour anyway.

Um... $200 is roughly?? 100 pounds? Somewhere around there. I've had an A500 since about '88 or '89... but it just isn't as much fun to code on.

Well moving sprites, etc is the same as reading at writing to RAM, 'cos of the way the ASIC worked. I guess you could probably do it, making use of line interrupts and stuff but it probably isn't really worth it in a game, the CPC is perfectly capable of software sprites. > > Depends on your definition really.

For example CPC software sprites could easily match C64 ones, without the limitations. Amiga's had the nicest H/W sprites 'cos of all that multiple depths and dual bitplane stuff. Before you say it I know C64 sprites can go in foront and behind the screen, CPC+ ones can't. > > Yeah, but if it'd had a fast processor and a good video display you > > could've done without them. > > _Could_ do without them, sure, but it's even nicer having them. > Agreed, up till the point where the processor starts getting faster.

Most _Pentiums_ have a hard time emulating the C64's I was waiting for this to come up! Given what I've heard here that the emulators are having such a hard time. But you have to remember: the Pentium is emulating the 6502, SID, VIC2 on a cycle to cycle basis on a much higher resolution screen.

What is the frame rate (sounds He'S referring to what I calla raster cut, casuing the VIC chip to duplicate the sprites. Each gets it'S own image. There is no flicker, the frame rate remains at 60Hz, as always. the only loss is a slight loss in the speed of the processor, since there is that software routine doing these raster cuts. Sprite size is still the same, 24x21 pixels. By using simple raster cuts (sometimes also called Multiplexers) you can stack sprites, to increase the size, with little loss in speed.

Increased speed doesn't immediately make the sprites bigger, or more detailed, it simply opens a door. If a programmer doesn't take advantage of this (which it appears that they do), you never see the increase. > 3. There is a point where the C64's 6510 can be sped up to to emulate the > C64's display hardware (I have no doubt Stephen's 20MHz 6510 can do it). Actually, due to the speed at which a regular C64 accesses it's display hardware, it'S not possible to outrun the stock screen. What is necessary for this to happen is a means to control and display video, without any slowdowns. In other words a video controller capable of handling the full onslaught of a 20Mhz bus. At this point, then it is possible to emulate the VIC chip itself to some extent. Of course all of this is pointless when you consider that the average programmer is going to use the extra speed for what it'S really needed for, i.e. math and graphics routines (rather than emulating some hardware feature). FWIW, I have one of these 20MHz accellerators, and am quite pleased with it. > You can argue what resolution is better for games.

The C64 is quite capable of doing high speed sprite-like graphics without using real sprites, or you can use a multiplexer routine, to let the hardware do most of the placement work for you. As explained above, a multiplexer uses a raster trick to make the video chip re-draw it'S sprites at certain points on the screen. I've seen as many as 64 unique sprite images on screen. The only limit is that you can still only have 8 sprites on any horizontal line, without using some other tricks (which tend to eat up processor power). > channels rather than just one.

I am also arguing that there were CPUs available at The hardware will never be completely obsolete, because there will always be a need for very small objects, for example a mouse pointer, various small game graphics, etc. No matter how you look at it, it still takes a bit less processor power to just let the hardware handle the small stuff. Even small graphics take processor time to implement. In the circles of 64 users, every cycle counts, so most of us spend hours looking for ways to optimise the programs we code. As an example, let'S say you have a routine that takes 100 cycles to execute. That means it can only execute about 10,000 times a second (let'S say it'S a sample player). Shave twenty cycles from this time, and your rate increases to 12,500 times a second. that'S a 25% increase in speed, by cutting twenty cycles. > If the 1MHz 6502 were fast enough, the programmers could take advantage of > the "hacked" video modes on the C64 and deliver some higher resolution > graphics in their games. I have to agree here -- PRogrammers do need to look at the accellerators we have, and write a few games that use the various extensions (such as 320x200x136 IFLI) for games. Or perhaps a Doom clone that uses a full 320x200x16 bitmap (as it stands, a 1Mhz machine is good for about 13 FPS at 40x50x16). > I don't know. Perhaps delivering to the lowest common denominator. The I always attributed this to one pure and simple concept -- the graphics are just too slow above 320x200 on most PC's. Too slow for a realtime Doom clone, or anything else requiring a minimum of 15 FPS updates. There'S no such thing as 'lowest common denominator' if you ask me -- I would say at least 90% of PC owners out there use a VGA or SVGA system, more than capable of much higher resolution displays. I figure if you can display a static 640x480x256 bitmap, then your machine had better be fast enough to put a 3D engine into this 640x400 bitmap, and maintain a 15FPS rate. Honest question, are there any games for the PC that handle this type of display? I don't know if there are or not. All of this said, I am one of my estimated 10% who don't have a VGA display, in fact my old 286 (my 'other' computer) is equipped only with CGA. > The processor is wasting time only if it has to wait between frames to > slow the game down. I view software driven features are far more cost > effective than hardware features - and they can improve with time. This is true, but this waste of time (i.e. slowing down the game) can be amortized in a much simpler way -- use smaller changes to your data. I.e. Let'S say you have a PC or other computer that updates a Doomor other 3D engine at 30FPS, and another machine that's twice as fast, that should handle 60FPS. Instead of simple wasting time between every other frame, cut your various 'changes' in half, to make the full frame rate of 60 FPS. In other words, make the graphics run smoother, with finer detail. Increase the display resolution. Use a larger display for the game. Increase the color resolution (use more colors). Add finer detail to objects. Use more realistic plotting for objects such as trees and wall fixtures. Make the sounds clearer, or put them in stereo if they aren't already. Basically a faster machine can still make good use of the same old hardware, you just have to be clever in how you program.. Trying to make a machine cheaper is pointless these days, when PC prices in the $1900+ range for a top of the line system. (ok ok we're talking C64 and Spectrum here, not PC, but you get the idea) > No. But I am going to claim that the special hardware is useless on > Stephen's 20MHz C64. He can do better in software. I agree to a point.. When you think about it though, there really isn't anything in the C64 that'S special compared to other machines with the same capabilities.. The VIC chip is our video 'card' The SID chip is our sound 'card' The CIA chips serve as parallel and serial ports The ACIA chip found in Swiftlink and Turbo232 cartridges is our high speed RS232 port. Like any other machine, there is something somewhere in the machine that sets a hard limit on the resolution and number of colors that can be displayed. The point that I agree with is that with a 20Mhz card like Stephan and I have, you could do much better plotting your own graphics (which really should not be termed as 'sprites'), only because the hardware sets a limit on the size of a single sprite. Of course this can be changed with a simple multiplexer routine, which had little affect on the machine's speed, but increases the number of sprites, without affecting the frame rate, andwithout any flicker (provided the routine is coded properly of course). We really need to get off this 'special hardware' thread, and think in terms of 'extra features' or whatever, since each machine still has some hard limit on what it simply can and can not do, in respect to the screen display. > Not true. The Spectrum was manufactured up to 1990 (?). The size of the The C64 was made up till 1992. > The C64 is not really upgradeable is it? (How many other than Stepehen > have a 20MHz C64). When you write software for your C64 do you target the I know of at least five others who also have this device. It is my understanding that at least 500 units have been sold. That may not seem like much, but it says something for the device, considering that it is farily new for the targeted market (less than 6 months old). The 20 Mhz accellerator is a plug-and-play device. You simply check the toggle switches mounted on top of the unit (to make sure the settings are right) and plug it into the back of the machine. Simple as that. If there'S a program that doesn't like the turbo mode, you can either flip the turbo switch to the off position, or issue a simple POKE command. If a program simply will not work at all, simply flip the disable switch and press the reset button. > original 1MHZ C64? The PC software writers don't target the 8086, 286, Depends on the application and the target -- If you are writing a program that simply is too slow to run at 1 Mhz, then set your target for 20Mhz, there'S 500+ of them out there already. If your program runs fairly well at 1Mhz, then set your target for the 1Mhz audience, but keep the support for the 20Mhz users. > money - why bother when the market share is in Pentiums? This is precisely why the lot of us stick with our old machines. Screw having to buy a $1900+ system to run some program that a wise coder could probably make run 100 times faster. Optimise, optimise, optimise! Case in point: GEOS 64 v2.0. In many cases I've seen my own system re-draw it'S screen and otherwise outdo some similar operations on a Windows 95 machine (a 486/33 to be honest). For crying out loud, a 486/33 should be at least a few times faster than a 20Mhz 65816 (the processor used in the 20Mhz C64 accellerator), since it has many more powerful features, a wider address bus, etc. It just all boils down to one simple this: What are you willing to do to make your program/machine run faster/better? _/ _/ _/_/_/ _/_/ _/_/_/ _/_/ _/ _/_/ _/_/_/ _/_/_/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/_/ _/ _/ _/_/_/_/ _/ _/ _/_/ _/-'-'_/ _/ _/-' _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/_/_/ _/_/_/_/ _/ _/ _/_/_/ natedac@dfw.net -- Specializing in Digital Sound on your Commodore Using BitchX for the IRC Rules!! -- Do *YOU* have the best!?

Hmm, doesn't exactly sound plug-and-play to me. What if the toggle switches are wrong? Do you then have to toggle them correctly by hand? Thought so. ;-) Try using a *real* plug-and-play PC device or better still an Amiga autoconfig compatible device then you'll really know what it means.

I think they are capable, but the investment isn't being made in the programming end.

In North America, the C64 came out in 81 or 82? This was a full two years ahead of the appearance of the US Spectrum and was the main reason Timex decided not to pursue the machine in the US.

True, it was also the precursor to the 68000 which came out in the *70's* The 6502 was designed by Chuck Peddle and co. who left Motorola because of some political thing. Chuck Peddle also designed the CBM PET.

Similar mnemonics, as in not as disparate as Z80. The 6809 has a MUL instruction, and you can remap Zero page to any page in memory. Also, more flexible indexed addressing.

If you make a mistake, someone will correct you. I expect that >when I make a "thoroughly mistaken" assertion that I will be corrected. I have two reasons: one of them is personal, the other is pragmatic. The personal reason is that among my many interests is a concept known as "reality", or, if you like, "truth". Reality has several interesting properties. One of the most important is that it doesn't care about opinions -- it simply exists. Since I like to maintain some sort of contact with reality, I try to have my opinions reflect it, or those parts of it with which I am familiar. The pragmatic reason deals with the medium we are presently using. One thing I don't think you've grasped is just who you are talking to. I of course do not mean myself, but rather the thousands of people who are reading these posts. And I would rather present myself to those thousands of people as a rational, well-reasoned human being instead of a soporific and sophistic ass. Anyways, what you have told me (and everyone else) so far, near as I can reckon, is that you possess: 1. No meaningful experience programming a 64. 2. No meaningful experience using a 64. 3. No more than a passing familiarity with the machine, its capabilities, and its software. >> In fact, you are free to increase the processor speed by a factor of twenty. >> If you think you can emulate sprites, well, I think you are quite wrong, >> and I'd like to see you try. > >And yet the humble Spectrum running a 3.5MHz Z80 can smoothly animate >larger and more sprites than the C64 and its special hardware. Since you seem to be an expert in this area, perhaps you should post some demonstration code. Since you don't know what sprites are on a 64, here are some issues for you to think about as you code up these smoothly animated sprites: How are you going to move the sprite? Do a block memory move? Don't forget to update the background to the value underneath, so you'll probably have to store it somewhere. When you draw the sprite, how are you going to handle the sprite to background priorities? How about when two sprites overlap, which will be displayed? Don't forget to pass through any graphics underneath if the sprite has a hole in it. And don't forget that the sprites can have different colors. Finally, don't forget to handle collisions. You need to detect if a sprite -- an arbitrarily shaped object, you know -- collides with the background, and/or if it collides with another sprite. A collision of course occurs when a colored (i.e. non-background) pixel in the sprite overlaps another colored pixel. As I said, you are free to take a 20Mhz processor to do this if you want. On the 64, this amounts to storing or reading a value from memory -- four cycles. >If the 20MHz C64 were available ten years ago, and you were making games >using the built in sprite hardware, your competition would bury you >because their software sprites would put your games to shame. Yes, the The expert speaks. One thing you guys seem completely unable to grasp is that a chip like VIC (which provides more than sprites, for instance text and bitmap modes, redefinable characters, video interrupts, and more) simply adds tools to your toolbox. In the case of VIC, they are very powerful tools indeed. What this means is that a programmer now has much more flexibility in deciding how to accomplish a given task. When the processor is upgraded, it means a programmer has just that many more tools. The amazing thing is that you haven't realized that your computer already has some custom chips in it -- the video display chip, for one. On an Atari 2600, for instance, the video display is handled by the processor. All game-related computations are done in the video blanking interval. By your so-called reasoning, a computer would be much better off to let the processor take care of updating the video display, instead of being "limited" by this custom chip. And why stop there? The first computer with a built-in instruction set was called MANIAC, built in the mid-50's (by my good friend Nick Metropolis, no less). Up to that time, it was up to the operator to even define the instructions. >The C64 survived in the low end 8bit market simply because the industry >moved to 16bits and a higher cost bracket.

Of course, you're totally right. All these years I've been playing spectrum games and I never even realized that the background was being deleted or that there was no collision detection anywhere.

Atleast their parser was really advanced and was able to parse out very complex sentences. In fact, their games were written in Z-machine code, which was a language especially invented for making these games. Because that code is interpreted, their games were very portable... oddly enough, I just checked out Infocom FactSheet and didn't find any information about releasing games for Spectrum. Maybe diskdrives just weren't enough popular on speccy? Drive was mandatory because games used drive as virtual memory (not writable though). : Then why didn't the Commodore bury the competition?

Are you claiming Speccy adventures are technically better ? What about the Infocom titles ? The Level 9 ones ? Magnetic Scrolls ? If these are not good enough please quote me some Spectrum titles that are technically better. Sure, there are *more* Spectrum adventures, and some are excellently written - which is in fact the main reason I use Speccy emulators - but there no reason to believe this is because the Spectrum is superior as a host platform for this kind of game. --- Bill Hoggett (aka BeeJay) IF GOD IS LIFE'S SERVICE PROVIDER WHY HAVEN'T I GOT HIS I.P.

Processor time isn't being wasted unless your waiting for a frame flyback (in which case it's safe to assume you probably didn't need the time) or you have to start dropping frames to keep things smooth, which suggests a very complex system like Freescape. Speccy games bunged sprites all over the place and ran at a lovely speed. It was the original poster who claimed it couldn't be done. > What amazes me about your post is that you're regurgitating issues > that have been steamrolled over and over umpteen million times in > this discussion.

I think perhaps the point is not being clearly made here. What the Speccy side is saying here is that the Speccy does not lose out by not having this in hardware - because the CPU is effectively as fast (possibly faster) than the VIC + 64 CPU in combination. >One thing you guys seem completely unable to grasp is that a chip like >VIC (which provides more than sprites, for instance text and bitmap >modes, redefinable characters, video interrupts, and more) simply adds >tools to your toolbox.

Generally true, but the reason for lack of Disk Drive support in Europe was the greed of Commodore. In their effort to make their price more attractive they cut out _all_ storage devices from the C64 as originally distributed. That's right, when my parents splashed out what was a considerable amount of money at the time (early 1984), the C64 came without _any_ storage device, or joystick, or any software at all. I had to save up my pocket money for ages before I could buy a tape drive. I remember writing a cricket game in BASIC - inspired by seeing Test Match on the Speccy - and leaving the computer on at all times because I had no way of saving my work. After the first power cut I always copied the code into a notebook at the end of the day in case of accidents. A disk drive was out of the question, since Commodore were charging more for that than the C64 itself. Disk drives. Pah, you were lucky... >Almost any program developed after 1985 in the US used this to great >advantage. In some cases, yes. However, it is my view that the restricted resources often resulted in higher quality, because the programmers were forced to push the boundaries of their machine rather than just use up a little more disk space.

On some PETs (BASIC 1.0?), you can type WAIT 6502,X and the word "Microsoft!" appears on the screan X times.

My dad had bought a 64 but no disk drive some months earlier -- my storage device was a pen and paper :). Disk drives were expensive here too but people abandoned their tape drives pretty darn fast. Of course, one of the main reasons for their cost is the fact that they are intelligent -- the 6510, 4k of RAM, etc. Expensive, but well worth the cost!

I guess the use of something is directly related to the skill of its user. I use BASIC for many things related to my research. I have written differential equation solvers, I have used it to investigate transcendental equations. I have a set of bifurcation equation coefficients which I use to compute various eigenvalues (related to relative pattern stability, if you're interested), which I have used BASIC to investigate. Using the BASIC hooks I wrote a set of very fast graphics functions (lines, points, circles). I use them for various things, including investigating various functions, plotting bifurcation diagrams for the above system, etc. I use BASIC to investigate many ideas I might have, and to investigate many mathematical things that I happen to come across. Finally, I use BASIC to prototype most of my algorithms (at least the complicated ones). Naturally, for computationally intensive tasks I don't use it; I have a nice HP workstation for them. For simple calculations I think its just great. -S From A.P.Cadley@uea.ac.uk Wed Jun 4 17:02:08 CDT 1997 Article: 68111 of comp.sys.cbm Path: news.acns.nwu.edu!newsfeed.acns.nwu.edu!news.ece.nwu.edu!news.cse.psu.edu!uwm.edu!spool.mu.edu!howland.erols.net!news-peer.sprintlink.net!news-pull.sprintlink.net!news-in-east.sprintlink.net!news.sprintlink.net!Sprint!194.159.255.23!disgorge.news.demon.net!demon!dispatch.news.demon.net!demon!earl.netcom.net.uk!netcom.net.uk!nntpfeed.doc.ic.ac.uk!sunsite.doc.ic.ac.uk!cpca3.uea.ac.uk!news From: "Andrew Cadley" Newsgroups: comp.sys.sinclair,comp.sys.cbm,comp.emulators.cbm Subject: Re: Spectrum Emulator for C64 Date: 30 May 1997 19:02:36 GMT Organization: University of East Anglia, Norwich, Norfolk, NR47TJ, UK Message-ID: <01bc6d2b$fa2e7060$04b8de8b@w9622136> References: <5maa2u$prl@news.acns.nwu.edu> <2854.7085T1021T2128@airtime.co.uk> <5mljkh$mk3@news.acns.nwu.edu> <01bc6ce9$97a53e20$04b8de8b@w9622136> <5mn4qv$d9i@news.acns.nwu.edu> NNTP-Posting-Host: oak1d.vlg1.uea.ac.uk X-Newsreader: Microsoft Internet News 4.70.1161 Lines: 58 Xref: news.acns.nwu.edu comp.sys.sinclair:38626 comp.sys.cbm:68111 comp.emulators.cbm:20693 Stephen Judd wrote in article <5mn4qv$d9i@news.acns.nwu.edu>... > In article <01bc6ce9$97a53e20$04b8de8b@w9622136>, > Andrew Cadley wrote: > >Commodore BASIC is absolutely useless. > > I guess the use of something is directly related to the skill of its > user.

It is a safe bet to assume that I have Maple and other powerful tools available on my extremely fast workstation(s), not to mention a good FORTRAN and C compiler. 2. I also use a calculator (and even a slide rule) from time to time. For instance, this morning I did my monthly checkbook balancing. 3. Earlier you stated that 8-bits were enough for almost all computing needs. Why does anyone use an 8-bit computer? A knee-jerk response is of course possible at this point, but I always advocate thought before action. Anyone can easily reason this one out. >> Using the BASIC hooks I wrote a set of very fast graphics functions >> (lines, points, circles).

Not only do my commands have their own keywords, they have their own tokens. (BASIC programs on the 64, and presumably ever other microcomputer, are stored in tokenized format). My program is literally an extension of the BASIC interpreter. As to being in ROM: no, actually I much prefer a fast command that does what I want to a fat, slow command that tries to satisfy every possible need. Besides, my algorithms are far superior. -S From A.P.Cadley@uea.ac.uk Wed Jun 4 17:02:21 CDT 1997 Article: 68451 of comp.sys.cbm Path: news.acns.nwu.edu!newsfeed.acns.nwu.edu!news.ece.nwu.edu!news.cse.psu.edu!uwm.edu!newsfeeds.sol.net!europa.clark.net!cpk-news-hub1.bbnplanet.com!news.bbnplanet.com!howland.erols.net!agate!nntpfeed.doc.ic.ac.uk!sunsite.doc.ic.ac.uk!cpca3.uea.ac.uk!news From: "Andrew Cadley" Newsgroups: comp.sys.sinclair,comp.sys.cbm,comp.emulators.cbm,comp.sys.amstrad.8bit Subject: Re: Spectrum Emulator for C64 Date: 3 Jun 1997 06:25:22 GMT Organization: University of East Anglia, Norwich, Norfolk, NR47TJ, UK Lines: 35 Message-ID: <01bc6fe6$daf85400$04b8de8b@w9622136> References: <5maa2u$prl@news.acns.nwu.edu> <01bc6ce9$97a53e20$04b8de8b@w9622136> <5mn4qv$d9i@news.acns.nwu.edu> <01bc6d2b$fa2e7060$04b8de8b@w9622136> <5mvmko$saq@news.acns.nwu.edu> NNTP-Posting-Host: oak1d.vlg1.uea.ac.uk X-Newsreader: Microsoft Internet News 4.70.1161 Xref: news.acns.nwu.edu comp.sys.sinclair:39002 comp.sys.cbm:68451 comp.emulators.cbm:20951 comp.sys.amstrad.8bit:6594 Stephen Judd wrote in article <5mvmko$saq@news.acns.nwu.edu>... > Since you asked, though, I will follow up to this one :) > > In article <01bc6d2b$fa2e7060$04b8de8b@w9622136>, > Andrew Cadley wrote: > This is why it's called a "hook".

Besides, my algorithms are far superior. Ah, but the point I was making is that on a CPC you could easily add commands to BASIC, it was just a case of setting a pointer to the command name and calling one of the firmware routines, you didn't need to write complex routines to patch it into the OS. In the case of ROM based routines it was actually automatically added at startup. ROM's can be an EPROM programmed by yourself so commands could be as complex as you required and the algorithms used were, of course, your own choice. RSX's (as they were known) didn't require tokens so you could add as many as you wanted, I assume this was not the case on the C64.

I'm honestly interested in why they were so slow.

That was a hangover from the VIC 20, the original design on the VIC had eight bits coming in at a time without assistance from the CPU and giving a pretty quick transfer. Trouble was, the chip doing the shifting was flawed, the register mucked about with other functions. So they had to put a dog-slow serial system in place which tied the CPU up. When the C64 came along it didn't *have* the flaw (different chip doing the I/O) and C= could have easily returned to their original idea and got the drive going *much* faster (about six times, max) but they wanted to retain backwards compatibility with the VIC, so the C64 had to put up with the same system, which got even *slower* because of the screen DMA.

I'm not sure about the urban myth, I got it from a "reputable" source, ie another protection expert told me. =-) Now if you want to talk *good* protection, the loader for "Venom Wing" (Amiga) by Thalamus was a prime example.

Ah, the old Ocean disk protection did something like that, there was an error on the disk that didn't come out the same when it was copied, and if the drive didn't report the same error it didn't let you in.

Well, most of the tape routines varied from average to pretty decent. Little tricks like reloading the header after the point where you lost control of the program, loading data backwards and that sort of thing. The *best* tape protection was never actually used, it was Powerload, coded by Cosine's very own Odie.

Sony use a similar trick in preventing their black Ps discs to be copied: (This is all from something I read in passing a year or so back, so I may be wrong on the finer details.) The first few sectors on the disc are coded as being damaged, and the PS checks for this during bootup. If it finds the sectros marked as unreadable, it continues with the bootup, and runs the game, if not, it hangs. Most cd burners have integral error checkers in them, and when copying a disc, if they find a damaged sector, won't copy it, so when the PS checks a gold disc, it finds blank sectors, instead of what it's looking for, and hangs. Pretty clever really - it's not easy to persuade a copier to actually copy damaged sectors, but there are ways around it... -- "My God...

We got it on the C64 too, and it sure wasn't any easier to "decode". I don't know much about the copy protection on C64 tapes, but many were a pain to copy on ordinary tape decks so I used a freeze cart.

Yeah, it's wierd that don't you think? The chickenheads could have made the C64 work with the 1540, along with a new, improved drive ala 1551 for the C16/plus4. CBM had BasicV4 installed in PETs long before the C64 came out. Looking back, methinks C= didn't expect floppy disks to catch on in a big way, else we would have had a fast drive with basic commands to operate it, just like with the 264 series. -- +-\___ ___ ______ __ __/=\=/=\=/=\=/=\=/=\=/=\=/=\=/=\=/=\=/=\=/=\-+ : / __)| _ \||_ _| /__/_/ "Bunch of savages in this town..." - Dante : |:__ \: _:: :: : @# '') Spammers, E-mail me for my real address... | `(____/|_|><|_||_|><><\__3- - -* <><><><><><><><><><><><><><><><><><><>' From jonathan@wolves4westbrom2.demon.co.uk Wed Jun 4 17:03:16 CDT 1997 Article: 67722 of comp.sys.cbm Path: news.acns.nwu.edu!newsfeed.acns.nwu.edu!news.luc.edu!chi-news.cic.net!su-news-hub1.bbnplanet.com!cpk-news-hub1.bbnplanet.com!news.bbnplanet.com!disgorge.news.demon.net!demon!dispatch.news.demon.net!demon!wolves4westbrom2.demon.co.uk!wolves4westbrom2.demon.co.uk!jonathan From: Jonathan Tranter Newsgroups: comp.sys.sinclair,comp.sys.cbm,comp.emulators.cbm Subject: Re: Spectrum Emulator for C64 Date: Mon, 26 May 1997 13:21:49 +0100 Organization: wolves4westbrom2 Distribution: world Message-ID: References: <337C5E94.388@actcom.co.il> <3389cd28.1468228@commodore64.com> <338852a1.4383537@news.demon.co.uk> <5maa2u$prl@news.acns.nwu.edu> NNTP-Posting-Host: wolves4westbrom2.demon.co.uk X-NNTP-Posting-Host: wolves4westbrom2.demon.co.uk [194.222.98.77] MIME-Version: 1.0 X-Newsreader: Turnpike Version 3.04 beta 4 Lines: 96 Xref: news.acns.nwu.edu comp.sys.sinclair:38083 comp.sys.cbm:67722 comp.emulators.cbm:20308 In article <5maa2u$prl@news.acns.nwu.edu>, Stephen Judd writes >Another expert speaks! >A great many people use their 64's for very useful work.

Hmmmmmmm... can't help thinking "the foreign concept..." line is going to send this discussion downhill somewhat! But thanks for educating us non-Americans about the advantages of a disk drive, it was really helpful. I remember having the tape version of Dragon's Lair on my C64. Dragon's Lair was a multi-stage game, and while you was playing one stage the next stage was loading in. The disk version didn't do this making it worse than the tape version, so the latter medium did have some better versions of games. Creating a usable computer that was affordable by most was the prime aim of Sinclair Research, and the fact that this meant using televisions, cassette recorders and (random-access) Microdrives was unavoidable. When disk drives did become cheaper I guess most Speccy users didn't find the need to upgrade for whatever reason, I don't know. The Spectrum did have reliable and fast 3.5"" and 3"" drives, and of course the former is still the standard storage medium today. Also at the risk of being wrong, was the humble Microdrive faster than the Commodore disk drive ? Even the standard Speccy tape i/o routines were nearly as fast as the standard C64 disk routines. >>it's benefit, but they pale in comparison to the fact that the spectrum >>was a more flexible, easier machine, and THAT'S why they sold more in >>the UK. > >And sold far less everywhere else in the free world. That's a very brave >logic you posess. Not *everywhere* else, no doubt you'll get a complete accurate list from other people. It's important to remember that Commodore, who are now dead (sadly for you Stephen, bought out by Europeans), had a much bigger marketing machine than a small outfit such as Sinclair. I think that the fact that in the UK (where Sinclair were able to compete with Commodore) the Speccy outsold the C64, is a good example of the Speccy's dominance. >You can argue with success, but not in the case of the 64.

Why not, because you don't want anybody to ? Also I don't understand "not much marketing". Commodore just produced the machine and didn't tell anybody about it, is that it ? How did Commodore undermarket the C64 compared to Atari, Sinclair or Amstrad ? >If you really don't understand the reasons, then I suggest that you >do a little research on the subject: visit some web sites, get ahold >of a 64, use a variety of programs on it, and try programming it. Most of us readers of any of the three newsgroups are quite researched on the subject otherwise we wouldn't subscribe. I speak for many people (although not all obviously) who owned both the Speccy and the C64 when I say that I much preferred my Speccy for a whole host of reasons.

Now, if you wanted a TAPE player for the C64, then that'd set you back another 50 or so. A disk drive would cost another 250 or so quid. So... For the price of 130, + maybe 15 or 20 quid for a good tape recorder, my 48K speccy had just as many games, a lot better, than the commodore.

About ten percent of our Commodore Zone covermounts are on tape. There are less users, but a *lot* of people still do. Not "real" users like us, people who actively *do* things, but games players who stuck with the C64 because they couldn't afford/be bothered with anything else. It's something I'd like to see killed off, but people still get in touch with most of the developers (Jon Wells, XL-C-US and so forth) wanting tape versions of their products and I still get customers in the shop where I work looking at the tape stuff on the shelf.

There are people, right now, in this so-called discussion, who seem to feel that a tape drive was actually _better_ than a disk drive when dealing with the C-64 or other 8-bits (or at least as capable as a disk drive), and that games and other programs can run equally well off of either, i.e. that a disk drive offers no practical advantage.

Absolutely not. But a C64 disk drive that took as long as my cassette recorder to load data does not appear to have any advantage over a tape drive that runs faster than my cassette recorder. And because of this slowness, the tape drive appeared to be as random access as the disk drive. Admittedly, it wasn't as reliable a medium. I know full well that the speed problem on the disk drive was later solved, so no need to post that here. The memory restriction ( on most software - some did do tape multiloads) generated some very talented software writers. I am still amazed at what they managed to pack into 48k (41 and a bit if not including the display file), including full screen scrolling of detailed background in arcade conversions like Green Beret.

The carry flag? >When you decide whether to add in the multiplicand to the running product, >what do you test? The carry flag? Perhaps I need to start underlining my words. Any competent 6510 programmer would call this an obvious use of the shift flag, not a clever use of the same. Actually any competent 6510 programmer who was interested in speed would abandon shift and add algorithms altogether. If you are interested in how modern chips do divisions, there is an article in a recent Siam Journal of Applied Mathematics on the Pentium FDIV bug -- as I recall, it amounted to a slightly incorrect number in a table. Now, back to chips. Since you (or whoever it was) never bothered to show me the simple comparison code between a Z80 and a 6510, I went and did a little research. As near as I can tell, the typical cycle count for a load or a store is around 7 cycles. On a 6510 it is 4. So, far, the Z80 seems around a factor of two slower (so that a 4MHz Z80 would indeed be faster). Then it became apparent to me that there is no kind of indexed mode. On a 6510, you can do an instruction like LDA $C000,X which will load the accumulator with ($C000+X), where X=register. All of the major instructions (load, add, subtract, or, eor, and) have this type of addressing mode, which takes 4 cycles (5 if a page boundary is crossed). The analogous Z80 isntruction seems to be ADD A,(HL) again, a 7-cycle instruction. Of course, on a 6510 this mode is used for all sorts of stuff, like drawing lines. To move to the next memory location, all that is required is an INX which takes 2 cycles. On the other hand, INC (HL) takes a rather large 11 cycles -- now we're up to a factor of five speed difference. The kicker, though, are the PC-relative instructions JR cond,e which take a whopping 12/7 cycles, and only test for Carry and Zero flags. On a 6510 the negative flag (high bit) may also be used as a branch condition; the instruction takes 3 cycles if the branch is taken, and 2 otherwise. Finally, the ROR type instructions are a factor of four faster on the 6510 (when dealing with the accumulator). So, what does this tell me? Not too much. If I was writing for a Z80, I would certainly write to its strengths and try to avoid its weaknesses, like I do on the 6510. But I would postulate that a Z80 is more than a factor of two slower than a 6510, and probably much closer to a factor of three on average. For doing raw calculations I would therefore expect a stock Spectrum to beat a stock 6510 easily, but of course any type of data (i.e. graphical) manipulation will slow down the computer by quite a lot. >If you want to be honest, nobody in everyday life needs more than an 8bit >machine to get day to day tasks done.

Yeah but you're *still* not taking into account the amount of data chuffing a 6510 has to do during real software. A Z80 does less because of it's larger set of general purpose registers and it's complex instruction set. > >If you want to be honest, nobody in everyday life needs more than an 8bit > >machine to get day to day tasks done. > > Agreed!

Well on the ZX microdrive the file was saved, asumming that there was enough room. As far as the user was concerned, the device appeared to be random access.

Since the (HL) instructions were only 7 cycles, I assumed that any sane programmer interested in speed would use them for indexing. If you really want to fix on IX type instructions for comparisons, your Z80 is now a factor of five slower than my 6510. Moreover, you can only index a byte off of them. The example I gave, in case you forgot it, was LDA $C000,X which takes 4 cycles. Of course, there is also zero-page indirect addressing as well, LDA ($FA),Y which adds Y to the 16-bit address in $FA/$FB, and loads the result into .A, at a cost of 5 cycles (6 if page boundary is crossed). Note that of course a simple INC $FA (three cycles) or self-modifying code is used when doing e.g. memory transfers (or drawing lines, for that matter). The point being that the Z80 does not have any sort of indexed mode [comparable to the 6510 modes][of value]. >> Finally, the ROR type instructions are a factor of four faster on >> the 6510 (when dealing with the accumulator). >> > >Is there somewhere on the net with lists of clock cycles for the 6510 and >Z80, I'd like to check some of these figures out?

For accomplishing the kinds of tasks that I write, a Z80 seems to be far more inefficient. As to comments like "Well a 6510 has to shuffle data that a Z80 could do in 16 bits", you could just as well say that a Z80 has to carry along all this 16-bit baggage when all you want to do is an 8-bit calculation. I think that if you had any programming experience on 6510s you might be able to make a more educated judgement on the matter. The Z80 seems to have some nice instructions and features that I wouldn't mind having on a 6510 (but have on a 65816 actually), but the reverse is also true, and the Z80 seems to go about some things in a very cumbersome way. Any sane programmer I'm sure takes advantage of the strengths and avoids the weaknesses of each. The only meaningful comparisons, at best, are classes of routines. For instance, on a 64 I can do an 8-bit multiply (16-bit result) in something like 34 cycles. I can draw lines at a rate of 20-30 cycles per pixel (including the plot of course). How long do these routines take on a Spectrum? (Neither of those routines involve loop unrolls and such). Also, just out of curiosity, how long does it take to store to graphics memory? Do you have to access it as a port? Many people were asserting that the computer can do 3D graphics faster because it can do calculations faster, but I find that the vast majority of time is spent in doing the graphics. The calculations are trivial. If you would like to know a genuine fact about the 64, it's that the memory layout for bitmaps is fairly cumbersome for doing many graphical manipulations. (Luckily, of course, the 64 programmer has more options than a straight bitmap). Actually the memory layout really blows; that's the one thing I wish the designers had done differently. >> >If you want to be honest, nobody in everyday life needs more than an >8bit >> >machine to get day to day tasks done. >> >> Agreed!

So do I, but it's been a while since I did any Z80. Since I'm at Uni and doing lots of C++ and stuff I didn't bother to bring my little book on Z80 which contains cycle times and to top it all off, it's slighty different on the Amstrad CPC because of the way the VGA accesses memory, creating the strange concept of NOP cycles. Strangely though I did bring my C64 manual, I think it got caught up in all the junk I had. Spooky. > >Yeah but you're *still* not taking into account the amount of data chuffing > >a 6510 has to do during real software.

You have to consider the fact that the Z80 has a faster clock (thus affecting cycle time) and more internal registers which can be used for a temporary storage space. > As to comments like "Well a 6510 has to shuffle data that a Z80 could do > in 16 bits", you could just as well say that a Z80 has to carry along > all this 16-bit baggage when all you want to do is an 8-bit calculation. A Z80 can chuff data in 8 bits as well so that doesn't really apply. > I think that if you had any programming experience on 6510s you might be > able to make a more educated judgement on the matter.

Congratulations, that's the point I was trying to make about having more registers etc. Just to re-mphaise the point, you should remember that 1 6502 cycle = roughly 3.5 Z80 cycles. > Also, just out of curiosity, how long does it take to store to graphics > memory?

The calculations are trivial. On all Z80 computers I've used the graphics display is memory mapped. So on the speccy you can change 8 pixels by writing a single byte. On the CPC it's either 8,4 or 2 pixels depending on the screen mode. > If you would like to know a genuine fact about the 64, it's that the > memory layout for bitmaps is fairly cumbersome for doing many > graphical manipulations.

Well the speccy's has a bit of an odd, hardware orientated layout as well. The CPC's is better, but still a little bit wonky. I agree about the 64 though.

Well yes, they were a bit crap, they did however operate at a decent speed, unlike the 1541. :-) Andy From NOSPAM@mindspring.com Wed Jun 4 17:05:23 CDT 1997 Article: 68176 of comp.sys.cbm Path: news.acns.nwu.edu!newsfeed.acns.nwu.edu!news.ece.nwu.edu!news.cse.psu.edu!uwm.edu!news-peer.gsl.net!news.maxwell.syr.edu!mindspring!usenet From: Radioactive Warrior Newsgroups: comp.sys.sinclair,comp.sys.cbm,comp.emulators.cbm Subject: Re: Spectrum Emulator for C64 Date: Sat, 31 May 1997 07:32:37 +0000 Organization: replace with for reply...

That's why you could access 50K on the Apple II if you removed the high res gfx and DOS. If my information is correct, you could access about 40K of RAM on a Speccy. This more than you could access on the C64 _in BASIC mode_, about 38K. However, the C64 also allowed you a further 22K accessible through machine code only.

Ah, no. Some games *did* cost the same, but the stock price for Speccy games was around the 7.95 UKP mark, whereas the C64 ones usually came in at 9.95 UKP. As time went on the prices became closer, but you only have to look through a few multi-platform computer games magazines of the early to mid-eighties to see that I'm right.

Fair enough, they did. 1.99 and 2.99 UKP to be exact. Wasn't it annoying to buy a full priced game only to see it relesed on a "budget" label eight or ten months later ?

A bad move by commodore cutting corners. I used my 64 for a long time for a lot more than just games. Come to think of it, there was a point where I didn't play any games. Now I use my 128 for the net, a 64 could do this just as well (tho slower). Ok ok so soft80 screens are difficult for some to read, so what. > And Beach Head II, Paperboy and others. Paperboy puts the border stuff so low (or high?) into the border area that I can't read the numbers, they're partially offscreen :) > And the 48K had more than the C64, which was 64K INCLUDING THE ROM. The > RAM of a C64 is more like 32K. Wrong. The C64 has 64K of RAM, 20K of ROMs, and 4K of I/O device space. The ROM's can be banked out (and usually are under any serious program) to reveal the entire 64K are if necessary. the memory map goes something like this: $0000-$00FF Zero Page $0100-$01FF Stack $0200-$03FF System variables for BASIC $0400-$07FF Screen memory for standard 40x25 text, plus some sprite pointers and a few unused bytes $0800-$9FFF About 38K Free RAM, always visible $A000-$BFFF 8K BASIC Rom, or RAM $C000-$CFFF 4K Free RAM, always visible $D000-$DFFF 4K System I/O, or Character ROM, or RAM $E000-$FFFF 8K Kernal ROM, or RAM $FFF0-$FFFF System interrupt vectors, etc. Under this memory map lies a full 64K ram from $0002 to $FFFF. $0000/1 are used for the processor's onboard 7 bit parallel I/O port controls. Every byte of the64K area can be used to program, tho it's not smart to use $0000-$1FFF or $FFF0-$FFFF since these are needed by both the processor and the user program to maintain the system. Even the area used by the screen can have a program running inside it, as is evident in many demos, you see the screen briefly fill with garbage, that'S actually some small program usually to de-pack or uncrunch the demo's data. > >> and the screen is always > >>in the same place in memory. > > > >Not on the 128K ones. Not in the 64 either. There are a few resitrctions, but you can move the screen anywhere you want, with the exception for $1000-$1FFF I believe it is, and another similar area above $8000. Those area conbtain ROM shadows which are only visible to the video chip, the processor still sees RAM in there areas.

Same reason. Changing the screen address on many machines is faster than swapping in a different bank of RAM.

After the standard screen is subtracted from this, 63K. (1K screen, 1K of banked color ram). 64K-9K=55K if you have a full bitmapped screeen turned on. (8K bitmap, 1K memory mapped color, and the 1K of banked color ram) > 2. Spectrum Graphics, although lower in colour quality, had finer > pixels, making for better detail of pictures. Can't argue there, but this too depends on which video modes you are comparing. Thru some fancy software tricks, you can get a 64 to do 296x200 in 16 colors (still some color clash, but not usually a problem if you are careful about how you draw).. Such a mode is called IFLI, and while exteremely processor intensive, does prove that the 64's gfx can be pushed pretty high, and this IFLI trick is well beyond what the hardware could do without software. In other wirds, with just the right software tricks, the C64 can do just about anything graphics wise, inside that 320x200 area. Seems many PC's (even my cousin's PSX and Super Nintendo) still use low res 320x200 or similar, for many animated graphics routines. > 3. In the advent of the AY chip in 128K speccy's, which, incidentally, > was easier to program, better tunes came out. I take it the AY chip is the Spectrum's sound chip? Remember tho just because something is easr to program, doesn't make it better, however I know nothing of the AY chip, and not a lot about SID, so I'll just shut up here.. I will say that a SID chip can do multi-track digital music quite easily. Modplay 128 is an example of this. Not the world's best sound comes from my program, but it does work (I'm not the world's best coder) :) > 4. Faster processor in the spectrum. I am curious.. Have all of us fogotten about the various accellerators for the 64? Turbo-Master (4.09Mhz), Flash 8 (8Mhz) and Super CPU (20Mhz) all give the 64 an edge. Far as I know the Flash-8 and the SCPU are the only two that are now available (the SCPU is fairly new, just came out 6 months ago or so) > 5. Faster loading of games on spectrum. What'S the typical load time for say, a 40K file? On a 64 you can load this in 3 to 6 seconds depending on the DOS cartridge you use. Most of these upgrades require nothing but the ROM cartridge, and no extra cables. Some old systemslike Dolphin DOS, are even faster. I've read claims of copying an entire 1541 disk (about 170K) in about 8 seconds. > 6. Easier programming language on spectrum.

Again, I don't know here, but I think that the 64 sold some 11 million units during it's 10-year lifespan, in the states. Not sure about other countries. > 9.

This is dependent on the person who programs the math routines, however in the end the Speccy should still outrun an unaccellerated 64, since the processor speed is the determining factor here, as opposed to fancy I/O hardware. > 11.

I would guess he was talking about BASIC. Sinclair BASIC is probably responsible for a lot more programmers being in the business of programming than any other version besides perhaps BBC BASIC. The 64, and to some extent the Amiga, both handicapped their users slightly because of the unfriendly programming environment. I would guess that a higher proportion of Sinclair owners actually got their hands dirty with some coding compared to CBM owners, simply because it was more accessible. The manuals supplied with early Spectrums were incredibly good - full 'learning to program' stuff, not just basic reference stuff. -- //// Damien Burke (replace d.c.u in address with demon.co.uk if replying) //// Spectrum pages: http://www.jetman.demon.co.uk/speccy/ //// New to this group?

A standard C64 and a standard C64 tape deck saves and loads at 300 bps.

With ordinary software, speed can be accellerated to about 25 times that of a stock system. No hardware add-ons, no tricks..

Albrecht: > With a text mode background screen and sprite hardware. How much memory > for the sprites & how much for some decent background? Well, depends on which mode. Stock char (multicolour) which is what's used for the average game is 2K a font, and sprites are quite small, 63 bytes each. So if you have 64 sprites, a font and a screen that's 7K, which fits under the Kernel ($E000-$FFFA) so it doesn't even take away from BASIC RAM. =-) That's about average for a small game, so there's 56K left for data, tables, music and code. If you want to use bitmaps, then it's 8K for the pic and 1K for the colour maps (for monocolour mode) and again, that can be placed under Kernel and the colour at $CC00 to keep it out of BASIC's way. Multicolour bitmaps take 1K more, at $D800. That's 10K, leaving 53K for the rest. Now, if you start using FLI, that's when RAM starts vanishing. The actual body of the pic is a standard bitmap, so it's 8K again, but the colour maps (there are eight of 'em) take another 8K and the second colour map (for $D800 again) a further 1K. So that's 17K for one picture. FLI's reserved for demos and intros, but there are some games that use it despite this limitation. -- Jason =-) _______________________________________________________________________ TMR / / / / / / / /\ / /__/ / / /__/ / / / /__/ Email: tmr@cosine.demon.co.uk / / / /\_/ / /__ / / / / __// Cosine Homepage: / / / /__/ / / / / / / / / / http://www.cosine.demon.co.uk / / /_____/_____/_____/__/__/__/_____/_____________________________________/ / \_____\_____\_____\__\__\__\_____\_____________________________________\/ From fungus@eskimo.com Wed Jun 4 17:07:37 CDT 1997 Article: 68042 of comp.sys.cbm Newsgroups: comp.sys.sinclair,comp.sys.cbm,comp.emulators.cbm Path: news.acns.nwu.edu!newsfeed.acns.nwu.edu!news.luc.edu!feeder.chicago.cic.net!su-news-hub1.bbnplanet.com!cpk-news-hub1.bbnplanet.com!cam-news-hub1.bbnplanet.com!news.bbnplanet.com!news.mathworks.com!mvb.saic.com!eskimo!fungus From: Fungus Subject: Re: Spectrum Emulator for C64 [additonal translation] In-Reply-To: <831.7086T612T2347@airtime.co.uk> X-Nntp-Posting-Host: eskimo.com Content-Type: TEXT/PLAIN; charset=US-ASCII Message-ID: Originator: fungus@eskimo.com Sender: news@eskimo.com (News User Id) Organization: Eskimo North (206) For-Ever References: <01bc6a5d$9855e4c0$04b8de8b@w9622136> <831.7086T612T2347@airtime.co.uk> Mime-Version: 1.0 Date: Thu, 29 May 1997 01:09:24 GMT Lines: 33 Xref: news.acns.nwu.edu comp.sys.sinclair:38520 comp.sys.cbm:68042 comp.emulators.cbm:20625 On 27 May 1997, Bill Hoggett wrote: > On 27-May-97 Andrew Cadley wrote: > > >XmikeX wrote in article <5majpp$amg@eyrie.org>... > >> > >> > >> The Starglider said : > >> > >> >1.

Each page can appear in any of eight 8k chunks of the 64k address space, including in multiple chunks. Each chunk can be programmed to behave as RAM or ROM. By adding another fast SRAM and reprogramming the GAL, I can have 32768 pages of 8k = 262GB of RAM, but I think that's a little nuts :-). I am working on preemptive multitasking support and interception of hardware interrupts. Just wanted to interject here because the connotation was that it couldn't be done on a Spectrum. You can do anything with a C64, Spectrum, whatever by adding the hardware you need.

By groups, Fungus means either demo coding groups, or software cracking groups... which still number in the dozens for the 64. Incidentally, many of us couldn't care less about how many emulators there are, although around 10 is about right. > Compare with 50 for the Speccy. That I know of. I don't know why you even bring this up?! What does this have to do with which computer is better? Although if this many people have made emulators, I would think that it must be a fairly easy task. And I know why it would be easy - the simpler a machine is, the easier it is to emulate.

I mean thin about it, if you only have a C64 then you're gonna defend it to the hilt wheter it's better or not. If however you've got say a PC, then any 8 bit machines you decide to emulate is a matter of personal choice. None of them are going to compare to your machine in terms of speed and hardware.

I've got Timex Sinclairs, VIC-20s, Amigas, PETs, Ataris, PCs, plus a whole bunch more video game units as well. The number of emulators available for a specific machine has VERY LITTLE to do with how good it is. The Amiga & Atari ST and others are far more powerful and similarly popular machines... and yet there aren't nearly as many emulators for those machines, especially the Amiga. Why? Because they are more powerful, and therefore more difficult to emulate, because the hardware does all sorts of extra work that the processor doesn't have to. > If however you've got say a PC, then any 8 bit machines you decide to > emulate is a matter of personal choice. None of them are going to compare > to your machine in terms of speed and hardware. Therefore the bigger demand > for spectrum emulators tends to suggest that the speccy was a more popular > platform. The fact is, that a C64 takes an absolutely hugely powerful machine (like a Pentium 133 or more!) to emulate close to fully - and it STILL isn't perfect. A simple machine like a Speccy is alot easier to emulate, as there is so much less hardware (particularly video) to emulate. So your average Joe programmer could go: "Let's emulate a PET" and do a reasonably good job, similarly "Let's emulate a Speccy", and with not all that much more difficulty do it (maybe even easier, if the Speccy is all bitmap driven, easier to port to a VGA screen, prolly). But when some guy goes "Let's emulate a C64", they suddenly get crushed by the difficulty in emulating it... and the few who manage to find that they need LOTS of computer horsepower to do all the work that the VIC does so easily. I mean, just emulating the sprite to sprite and sprite to screen data collision requires numerous AND's for EVERY SINGLE pixel on the screen, every single frame... How many is that? Well, 320*200 is 64,000 pixels * 16 (for 8 sprites colliding with each other + those same 8 hitting the background graphics) * 60 frames a second... about 61 million ANDs per second... and you're telling me the 64's hardware isn't powerful? The above numbers aren't exact, but give the idea... and that's just a small part of what the hardware is doing... Additionally, you seem to be confusing popularity with power... however, it's absolutely ridiculous to say that the Spectrum was more popular world-wide than the 64... this is a quantatative thing... there are simply more C64's in existence than Speccy's. And FAR more real 64's being used than Speccy's: Most of the gung-ho 64 dudes are still using the real thing. That's a further testimony to it's brilliant design, and LASTING popularity. > Oh, and there are two Amiga emulators, UAE and another one whose name > escapes me right now. > > > I could make an abacus emulator... how about a lightbulb emulator? > > Emulating an abacus on a C64 could be *very* tricky, it's just not fast > enough. Put a demo like Dawnfall running on an absolutely stock 64 next to ANY Speccy, and you'll see what good coding and good use of the 64's hardware can do for a lowly 1Mhz machine :) Robin From A.P.Cadley@uea.ac.uk Wed Jun 4 17:08:20 CDT 1997 Article: 68088 of comp.sys.cbm Path: news.acns.nwu.edu!newsfeed.acns.nwu.edu!news.ece.nwu.edu!news.cse.psu.edu!uwm.edu!cs.utexas.edu!howland.erols.net!newsxfer3.itd.umich.edu!news-peer.sprintlink.net!news.sprintlink.net!Sprint!news.mathworks.com!news-xfer.cybernet.dk!baron.netcom.net.uk!netcom.net.uk!earl.netcom.net.uk!netcom.net.uk!nntpfeed.doc.ic.ac.uk!sunsite.doc.ic.ac.uk!cpca3.uea.ac.uk!news From: "Andrew Cadley" Newsgroups: comp.sys.sinclair,comp.sys.cbm,comp.emulators.cbm Subject: Re: Spectrum Emulator for C64 [additonal translation] Date: 30 May 1997 15:18:52 GMT Organization: University of East Anglia, Norwich, Norfolk, NR47TJ, UK Lines: 86 Message-ID: <01bc6d0c$b90244a0$04b8de8b@w9622136> References: <337C5E94.388@actcom.co.il> <3389cd28.1468228@commodore64.com> <5majpp$amg@eyrie.org> <01bc6a5d$9855e4c0$04b8de8b@w9622136> <338a9a4d.2670950@news.demon.co.uk> <3393c16b.1809106@news.demon.co.uk> <338DD49E.52C7@tbaytel.net> <01bc6c89$ae5d4a00$04b8de8b@w9622136> <338EE6D2.23A6@tbaytel.net> NNTP-Posting-Host: oak1d.vlg1.uea.ac.uk X-Newsreader: Microsoft Internet News 4.70.1161 Xref: news.acns.nwu.edu comp.sys.sinclair:38600 comp.sys.cbm:68088 comp.emulators.cbm:20668 Robin Harbron wrote in article <338EE6D2.23A6@tbaytel.net>... > Andrew Cadley wrote: > [snip] > The Amiga & Atari ST and others are far more powerful > and similarly popular machines... and yet there aren't nearly as many > emulators for those machines, [snip] > Yeah, but there 16-bit machines so *obviously* require more processor power.

I think there's a lot of confusion here about what can be done and what has been done. Speccy emulation, for example is easier on a PC than on an Amiga. Not because the PC is nessacarily better but due to various similarites between the Z80 and the Intel 80x86 range (same flags layout etc) Sprite collisions DO *NOT* need to do checks with every single pixel on the screen. That's a ridiculous statement. They only need to do checks in areas underneath the sprite. If emulators are checking every pixel it's no wonder you reckon on needing a P133. I still think that this boils down to sloppy coding in C64 emulators. The CPC has similar (in fact better) graphical capabilites to the C64 and can, and has been successfully emulated on the PC. Paul Hodgson is coding a CPC+ emulator for Windows 95 and yet he seems to be doing alright at getting C64esque hardware running okay. A dificult task given that a CPC+ sprite can have up to 4 pixels for every ordinary on screen one. Add to this DMA music in the background and your definately competing on similar grounds. > Additionally, you seem to be confusing popularity with power... however, > it's absolutely ridiculous to say that the Spectrum was more popular > world-wide than the 64... this is a quantatative thing... there are > simply more C64's in existence than Speccy's.

No, your the one confusing popularity with power. As I see it, the better machine is the one that most people, given a free choice, would use. Speccy emulation is more popular and I don't believe this is just down to emulation difficulties. If more people were interested in emulating the thing, more people would be trying to do it. > Put a demo like Dawnfall running on an absolutely stock 64 next to ANY > Speccy, and you'll see what good coding and good use of the 64's > hardware > can do for a lowly 1Mhz machine :) > And there are plenty of top demos for the speccy too. I was never really into the demo scene but I'm sure someone could point out a mass of spectacular ones. Of the few I did see Shock and the NMI 3 demo were very impressive.

He claimed that, for a single 24*21 sprite on a 320*200 screen, you'd need to perform 64000 pixels checks. One for each pixel on the screen. That's what I said was ridiculous, since you obviously only need to do 504 checks (the area underneath the sprite). Further to this you can do all sorts of clever stuff to check for overlap as you drew the sprites. > >I still think that this boils down to sloppy coding in C64 emulators.

Well as a CPC+ coder, which also has H/W sprites, multicolour bitmaps, raster interupts etc. I'm surprised you feel the need to level such charges at me. I suspect you read my reply without really considering the original posters comments which were way out. > >> Put a demo like Dawnfall running on an absolutely stock 64 next to ANY > >> Speccy, and you'll see what good coding and good use of the 64's > >> hardware > >> can do for a lowly 1Mhz machine :) > > I will again plug my own lowly dim4, available on my web page.

Are you prehaps refering to a redefinable character set. The speccy had one and it was easier to use than on the C64. However that's rather irrelevant since Speccy coders used software sprite techniques to produce lettering and such like, *much* more flexible. > BTW: Note to Spectrum users. It is a "vector" demo.

Yes but it's not a vector game is it. Games have far more restrictinos than demos because you've got to deal with all player related stuff. In a demo you only need to concentrate on the effect.

What happened is that I slammed Fungus for his attitude and specifically the statement :" ..who gives a fuck about Emu's anyways, they suck, real thing or nothing!". What you did was misinterpret that on the basis that Fungus is a fan of real C64s, and since I criticised Fungus, I must be against real C64s. QED ? Nope.

No doubt you know Fungus better than I do, but I can only go on those posts of his I have read. This doesn't change the fact that I also react badly when sceners call me a lamer or worse simple because I'm not a member of a group or into demos. >> Just so everyone knows, I still have my old C64 (though it's faulty >> nowadays) as well as over 300 original boxed titles.

The fastest C64 emulator (which doesn't emulate the C64 at 100%) needs at least a 486/100 with a fast video card to get full speed without skipping frames. The sound emulation is not very good, and, of course, doesn't emulate SID filters and some VIC screen effects. CCS64, one of the best C64 emulators, needs a Pentium 133, and that's without emulating the SID filters! >So as you can tell from this it is more complex to emulate a C64 (taking >into consideration all its processors) than to emulator a speccy.

We have the same mode (there was a slideshow released about 1985 with a lot of Speccy loading screens) but our res is a bit higher (the C64's screen is 40 characters wide and 25 high, so our screen is 320*200 pixels). And with a bit of prodding at the VIC chip, it's possible to extend that out into the side borders, adding a maximum of 96 pixels, making it 416*200.

Okay, well if you think that's the case I won't mention hard disks, RAM expansions, printer interfaces, fast modems and GEOS then. Ever seen a Spectrum with 1Mb of RAM and 1Gb of hard disk, a 3.2Mb floppy drive and a 14k4 modem, all remounted in a tower case? I've seen a C64 like that. And it had an accellerated processor. As for my own personal needs, well my C128D, 1541, 1581 and Action Replay (along with a C64B, 1541 and another AR) cover most of the jobs I do with the C64. The only reason I don't take it online is that it's normally doing other jobs whilst my Amiga takes care of internet stuff and I don't want to tie it up. (At the mo, the C128D is Timecrunching a file and the C64B is running a demo, err... [Checks disk] Cucumber Juice 2 by the Hitmen.) > 10.

Okay, a few back at you: 1) The C64 has more video modes, one matching the Spectrum (with hardware sprite support and a wider screen), two of a lower resolution with better colour control and two character modes. As well as all the "created" modes, such as FLI (16 colours per char, 148*200), AFLI (16 colours par char, 296*200) IFLI (16 colours per char, 296*200 interlaced) and IAFLI (16 colours per char, 592*200 interlaced). 2) The VIC chip has some extra, undocumented "features" that can be used to a programmers advantage, allowing bitmaps to be scrolled at a vast speed (32 pixels a frame, 50 frames a second, for example) and, with a mask at the top of the screen, in all directions too. It's possible to open the upper, lower and sideborders to expand the screen, reposition the hardware sprites, making more available (the record stands at 120 sprites, all moving over a bitmap, by Crest), alter the smooth scroll value on every rasterline, produce repeated chars in the upper and lower borders and swing them around and a myriad of other possible tricks. A simple example, try scrolling the whole Speccy screen one screen width horizontally in under 1,000 cycles. I can do it on the C64, at a speed of eight pixels a frame. That works out at 10,000 bytes of data shifted in one 50th of a second. 3) The SID chip is more flexible than the AY. Due to the extra control of the waveforms it's possible to emulate up to five channels on the stock three, and play polyphonic digi sound over that, giving a total of seven channels. Add to that note multiplexing and arpeggio and you can gain another three or four pseudo channels. You also get ring and sync modulation, two filters which can be applied to any or all channels and with the assistance of multi-speed players the sound quality and flexibility can be increased further. 4) Large active user base (not solely relying on retro gaming and/or emulation, most C64 users of old are *still* C64 users *now*). -- Jason =-) _______________________________________________________________________ TMR / / / / / / / /\ / /__/ / / /__/ / / / /__/ Email: tmr@cosine.demon.co.uk / / / /\_/ / /__ / / / / __// Cosine Homepage: / / / /__/ / / / / / / / / / http://www.cosine.demon.co.uk / / /_____/_____/_____/__/__/__/_____/_____________________________________/ / \_____\_____\_____\__\__\__\_____\_____________________________________\/ From A.P.Cadley@uea.ac.uk Wed Jun 4 17:12:54 CDT 1997 Article: 67804 of comp.sys.cbm Path: news.acns.nwu.edu!newsfeed.acns.nwu.edu!news.luc.edu!chi-news.cic.net!feeder.chicago.cic.net!su-news-hub1.bbnplanet.com!cpk-news-hub1.bbnplanet.com!news.bbnplanet.com!rill.news.pipex.net!pipex!baron.netcom.net.uk!netcom.net.uk!earl.netcom.net.uk!netcom.net.uk!nntpfeed.doc.ic.ac.uk!sunsite.doc.ic.ac.uk!cpca3.uea.ac.uk!news From: "Andrew Cadley" Newsgroups: comp.sys.sinclair,comp.sys.cbm,comp.emulators.cbm Subject: Re: Spectrum Emulator for C64 Date: 27 May 1997 06:15:10 GMT Organization: University of East Anglia, Norwich, Norfolk, NR47TJ, UK Lines: 222 Message-ID: <01bc6a65$46f2f520$04b8de8b@w9622136> References: <337C5E94.388@actcom.co.il> <5li6cc$mbv$8@gerry.cc.keele.ac.uk> <9705261105.AA00fms@cosine.demon.co.uk> NNTP-Posting-Host: oak1d.vlg1.uea.ac.uk X-Newsreader: Microsoft Internet News 4.70.1161 Xref: news.acns.nwu.edu comp.sys.sinclair:38183 comp.sys.cbm:67804 comp.emulators.cbm:20395 Jason wrote in article <9705261105.AA00fms@cosine.demon.co.uk>... > The Starglider: programmer. > > > 2.

Have to disagree there. having owned both I'd say that the AY *definately* produced better music. Though most speccy software, even demos, never really pushed it.

Hmm, I think that's just 'cos commercial interest in the speccy was gone before Doom clones became the only thing people wanted to program. ;-) radical software apparently had an almost finished doom clone for the CPC until commercial interest disappeared there, so I guess there is nothing to stop the speccy having one. How do they do that? > > These were what I could remember at the moment, I did used to have a > > list of about 25 reasons why, but I've forgotten! > > Okay, a few back at you: > > 1) The C64 has more video modes, one matching the Spectrum (with hardware > sprite support and a wider screen), two of a lower resolution with better > colour control and two character modes.

The CPC can easily whip any of those modes, which is teh reason that I still beleive it was the best of the three *main* eight bits, even before you take into account the 'plus' features which make the C64's sprites look pathetic. > 2) The VIC chip has some extra, undocumented "features" that can be used > to a programmers advantage, allowing bitmaps to be scrolled at a vast speed > (32 pixels a frame, 50 frames a second, for example) and, with a mask at > the top of the screen, in all directions too.

Once again, effects such as this were all done on the CPC (even Hardware sprites on the machines that never had them) only better. Take into account the plus machines, which could manage *pixel* perfect hardware scrolling (this could be done on older ones at full screen width) in all directions, split screens, 4096 colour displays and 16 colour hardware sprites at a resolution equivalent to 640*200. The CPC could even manage this in games, and not just fancy demos, see Prehistorik II or Cauldron III for classic examples. > A simple example, try scrolling the whole Speccy screen one screen width > horizontally in under 1,000 cycles.

You could easily do this on the humble CPC, with it's lushious hardware scrolling. On a plus you could probably do it pixel by pixel, without shifting a single byte of data at all. I reckon you could probably match the frame rate on a speccy, given the speed of an LDIR instruction, although exactly how you'd compare cycles given the difference in processor speed/instruction cycle length. > 4) Large active user base (not solely relying on retro gaming and/or > emulation, most C64 users of old are *still* C64 users *now*). That surely is 'cos C64 owners were *always* too cheap to upgrade to a better machine, like say .... .. a speccy. :-) Andy From A.P.Cadley@uea.ac.uk Wed Jun 4 17:12:57 CDT 1997 Article: 67814 of comp.sys.cbm Path: news.acns.nwu.edu!newsfeed.acns.nwu.edu!news.luc.edu!chi-news.cic.net!su-news-hub1.bbnplanet.com!cpk-news-hub1.bbnplanet.com!news.bbnplanet.com!disgorge.news.demon.net!demon!dispatch.news.demon.net!demon!baron.netcom.net.uk!netcom.net.uk!earl.netcom.net.uk!netcom.net.uk!nntpfeed.doc.ic.ac.uk!sunsite.doc.ic.ac.uk!cpca3.uea.ac.uk!news From: "Andrew Cadley" Newsgroups: comp.sys.sinclair,comp.sys.cbm,comp.emulators.cbm Subject: Re: Spectrum Emulator for C64 Date: 27 May 1997 06:57:54 GMT Organization: University of East Anglia, Norwich, Norfolk, NR47TJ, UK Message-ID: <01bc6a6b$3f428420$04b8de8b@w9622136> References: <337C5E94.388@actcom.co.il> <5li6cc$mbv$8@gerry.cc.keele.ac.uk> <9705261105.AA00fms@cosine.demon.co.uk> <01bc6a65$46f2f520$04b8de8b@w9622136> NNTP-Posting-Host: oak1d.vlg1.uea.ac.uk X-Newsreader: Microsoft Internet News 4.70.1161 Lines: 24 Xref: news.acns.nwu.edu comp.sys.sinclair:38193 comp.sys.cbm:67814 comp.emulators.cbm:20401 Andrew Cadley wrote in article <01bc6a65$46f2f520$04b8de8b@w9622136>... > > > Jason wrote in article > <9705261105.AA00fms@cosine.demon.co.uk>... > Have to disagree there. having owned both I'd say that the AY *definately* > produced better music.

The C128 runs at slightly under 2 Mhz, counting for slight bottlenecks in I/O access. This program runs on the 128 and uses a ram expansion unit.

Yeah but how much of the processor power was used, on the CPC+ you didn't need any. You could probably do something similar on the Speccy but you'd need a fair bit of the processors time.

I have a CDROM of 150MB of zipped Amstrad CPC programs. A lot less than you can find for the Spectrum or the C64, but a 150MB of zips for a 64KB computer is quite a few games and programs. --- Ivar Fiske From damien@jetman.d.c.u Wed Jun 4 17:13:21 CDT 1997 Article: 68519 of comp.sys.cbm Path: news.acns.nwu.edu!newsfeed.acns.nwu.edu!news.ece.nwu.edu!news.cse.psu.edu!uwm.edu!chi-news.cic.net!feed1.news.erols.com!worldnet.att.net!europa.clark.net!disgorge.news.demon.net!demon!dispatch.news.demon.net!demon!jetman.demon.co.uk!not-for-mail From: damien@jetman.d.c.u (Damien Burke) Newsgroups: comp.sys.sinclair,comp.sys.cbm,comp.emulators.cbm Subject: Re: Spectrum Emulator for C64 Date: Tue, 03 Jun 1997 20:16:02 GMT Organization: Ha!

Normally the case. I spent most of the last five years realigning C64 tape decks though, where some wally had dropped it or it had been knocked about during a move (or in some cases, had just worn a lot)... My own deck is some fifteen years old and still works perfectly. I've only ever aligned it four times and cleaned it twelve. It came with my VIC 20 and has been running on my C64, C64C, C64B, C128 and C128D in order with no more than a few mis-loads. Compared to the CPC464 and the deck we put onto the Speccy+ we used to have at work it's been wonderful. =-) -- Jason =-) _______________________________________________________________________ TMR / / / / / / / /\ / /__/ / / /__/ / / / /__/ Email: tmr@cosine.demon.co.uk / / / /\_/ / /__ / / / / __// Cosine Homepage: / / / /__/ / / / / / / / / / http://www.cosine.demon.co.uk / / /_____/_____/_____/__/__/__/_____/_____________________________________/ / \_____\_____\_____\__\__\__\_____\_____________________________________\/ From damien@jetman.d.c.u Wed Jun 4 17:13:28 CDT 1997 Article: 68387 of comp.sys.cbm Path: news.acns.nwu.edu!newsfeed.acns.nwu.edu!news.ece.nwu.edu!news.cse.psu.edu!uwm.edu!chi-news.cic.net!su-news-hub1.bbnplanet.com!news.bbnplanet.com!newshub2.home.com!news.home.com!howland.erols.net!europa.clark.net!disgorge.news.demon.net!demon!dispatch.news.demon.net!demon!jetman.demon.co.uk!not-for-mail From: damien@jetman.d.c.u (Damien Burke) Newsgroups: comp.sys.sinclair,comp.sys.cbm,comp.emulators.cbm Subject: Re: Spectrum Emulator for C64 Date: Mon, 02 Jun 1997 18:10:55 GMT Organization: Ha!

I'll correct every single person who I have to, until this single fact is understood: The C64 does and always has, since it's inception in 1982, had 64K of base RAM, almost every byte of which is free to program in (minus 1K for the text screen, or 9K for a full multicolor or hires bitmap screen).

Although you dismiss the C128 quite easily, you may not be aware that the C128 houses both a 6502 series CPU and a Z80B (and sometimes A). The following discussion between myself and a friend might be of interest.. : I think I will stick to 8502 code, as it appears that my best efforts in : z80 are less than 40% of what I could do otherwise.. : : This is what the Zilog manual tells me.. : : LD DE,TAB2 ; load, (D,E) = destination address : LD HL,TAB1 ; load, (H,L) = source address : LD BC,100 ; load, (B,C) = number of words : LDIR : : The transfer is made by LDIR and the stats for this little exercise : should be 20+16+20+2095 total cycles? Ok, so roughly 21 cycles per byte? : I'm sorry, but this just blows.. There has got to be a better way in : z80? Right? Sure, it has brain-dead microcode but.... ? -- If I were you, I would stick to the 8502. Both it and the Z80 are clocked at the same rate (even though the 128's z80b is rated for 6 mhz). Anyways, at the same clock rate, the 6502's are demonstrably faster. Their speed comes from simplicity. Hard-wired instructions, short execution times, and an early form of pipelining. Anyways, without any mental effort expended, here is very simple 6502 code that will move 2x as many bytes as the z80 code above but in the same # of cycles! ldx #49 ldir lda tab1+50,x sta tab2+50,x lda tab1,x sta tab2 dex bpl ldir 2 bytes moved in 21 cycles or 10.5 cycles average. The overhead is 1 cycle. See, already I have beat Z80 code. In fact the 128 has a special feature to do even better: a relocatable zero page and stack. I don't know exactly how to move the zero page, but it's something like this: lda #>tab1 sta stackpagehigh lda #>tab2 sta zeropagehigh ldx #49 txs ldir pla ;read tab1,sp and decrement sp tsx sta from 2 to 7 (or even 9 with undocumented opcodes). The z80 is very inefficent and starts at 3 and ranges up to about 24 cycles. So for example a 16 bit register add on the z80 takes 14 cycles while this is only 3 or 4 cycles on the 8502. On average the 8502 can run the same task as well or better than a z80 at twice the speed. The difference for the cycle times is due to pipelining. This is a technique to reduce the cycles in a cpu, and is used in new RISC processors. The 6502 has pipelining making it very efficient. There are 3 stages which are executed in parrallel for each instruction. Instruction decode, alu, and something else. I need to look this stuff up. But the 6502 is always fetching the next instruction at the same time as it's figuring out what to do with the current one, so when the current one is finished, it's part way through working on the next one. Something like an assembly line. :) --George -- Pursuant to US Code, Title 47, Chapter 5, Subchapter II, 227, any and all nonsolicited commercial E-mail sent to xmikex@eyrie.stanford.edu or xmikex@eyrie.org is subject to a download and archival fee in the amount of $500 US.

The CRTC was a standard chip manufactured by Motorola and Hitachi amongst others.

Actually, until the 68060 the Z80 was the most complex processor to be built without *any* microcode. As for the LDIR instruction, yes there are better ways, but there not so compact. Anyway 21 cycles isn't so bad on a Z80 'cos it was clocked faster than the 6502, although I suspect your count is wrong. I don't have my Z80 documentation with me but I certainly don't recall them needing that many cycles. > If I were you, I would stick to the 8502.

IIRC the C64's 6502 was running at about 2Mhz, the Speccy's Z80 was running at about 4Mhz. >Anyways, > at the same clock rate, the 6502's are demonstrably faster. Their speed > comes from simplicity.

The Z80 has a stack as well, what kind of silly point is that. As for a relocatable zero page, the Z80 doesn't need one 'cos it's index registers can access all of the 64K address range, unlike the hideous restriction on the 6502. Anyway as I said the Z80 is clocked faster, so you may require more cycles but it *still* runs faster. I seem to remember putting both machines head to head in my youth and the speccy finished first.

Straight tests like the ones you show above don't really show of the Z80 in it's best light. You really need to show some slightly more complex examples to demonstrate effectively. Then you'll see the relative ineffiency of 6502 'cos it can't store all that much in its registers.

I don't know The C64 runs close enough to 1MHz (slightly less for PAL, slightly more for NTSC) with *or without* the screen on. By turing the screen off, all you do is eliminate the VIC's DMA cycles, giving the CPU the full bandwidth of the bus. The net speed up is hardly noticeable. -- Because the junk mailers of the world think my address is their play thing, my e-mail address will not be revealed.

I am quite happy to say that C-64 programmers at least are aware of the difference between cycles and cycles per second. Although I admire your persistence and stamina I wish it was not inversely proportional to the technical level displayed. Oh how I yearned, how I prayed, for even one comment with technical merit -- some code, perhaps, nay, even the tiniest hint of an algorithm for performing a computational task.

You would do better to emulate Francis Bacon than Aristotle. The statements don't become true merely by repetition or speaking loudly, either. Some of these statements might be "Sprites are easy to do in software", "software sprites on a Spectrum are faster than C64+VIC sprites", "any piece of code will run faster on a Spectrum's Z80", and so on. You ought to try writing some of these simple and straightforward algorithms sometime. Post the code here, along with cycle times (and for Heaven's sake man, none of this "equivalent cycles" lunacy). Then we'll see what's what, and with whom, where. Brush up on your mathematical and 3D algorithms too, and we'll see how they compare with mine. I was furthermore hoping that at least one person would take the time to look at some of the example code and programs I suggested, but apparently it too was too much to ask. I for one would have been interested in seeing how they compare with Spectrum programs, and also comparing Z80 algorithms with 6510 algorithms. But it seems that the theme of this so-called discussion was fact by declaration, not facts for illumination. I think I would rather go do something illuminating.

Not everything. You will be able to construct scenarios where the 6502 will run faster, but I will be able to construct far more. The reasons I gave concern chip architecture - I have not yet had anyone address this. I may have made it seem that the Z80 only had advantages in comparison to the 6502, but that's because I'm arguing one side. I thought you, perhaps, would sing the praises of the 6502 which deal with its fabulous addressing modes. > You ought to try writing some of these simple and straightforward > algorithms sometime. Post the code here, along with cycle times OK. > (and for Heaven's sake man, none of this "equivalent cycles" lunacy). Equivalent cycles are *very* relevant, Stephen. The number of cycles needed to complete a task has very little to do with how fast it gets done and an awful lot to do with how the chip architecture was designed. > Then we'll see what's what, and with whom, where.

You have a head start on me since you've done it already on the 6502 and I haven't done this on a Z80.

Some of these statements might be "Sprites are easy > to do in software", "software sprites on a Spectrum are faster > than C64+VIC sprites", "any piece of code will run faster on > a Spectrum's Z80", and so on. Since when did I claim software sprites are easier? Hardware sprites are *much* easier to use, I wouldn't disagree with that. What I actually said is that software based sprites are more flexible, given the fixed size of H/W sprites and other limitations such as priorites. > You ought to try writing some of these simple and straightforward > algorithms sometime.

Well much as I'd love to code the routines to emulate C64 sprites *exactly* on a CPC screen, I'm afraid I really don't have the time. I'm off on hols in a couple of days and I've got better things to do with my time. However I have crossposted this thread to c.s.a.8, so if anyone else wants to do something similar I'm sure they will. BTW, what's wrong with 'equivalent cycles', all it does is provide a more logical way of comparing routines. Obviously if you just count cycles, the C64 routine will appear to be faster. If you account for the speed difference the comparison is more reliable, like P numbers on Pentium compatible processors. > I was furthermore hoping that at least one person would take the time > to look at some of the example code and programs I suggested, but > apparently it too was too much to ask.

We were discussing how the LDIR command works, in case you didn't read it properly. It is true that for memory fills and other specialised operations, using the stack can be quite a bit faster.

No, that would be slower. Relocating the stack then pushing zero's however was the fastest way of clearing memory IIRC.

You need only look at the CPU cycle sheat to see how the 6502ish CPUs worked compared the the z80s... No putdown on the z80s... Most CPUs took 4 cycles to get even the most basic commands done I think the Z80 took 2 cycles for most commands and the 6502ish chips got most commands done in one cycle... the 68000 line BTW could get things done in halfcycles... : As for a relocatable zero page, the Z80 doesn't need one 'cos it's index : registers can access all of the 64K address range, unlike the hideous : restriction on the 6502.

Except there were also at least two Z80 cycles for each 6502 cycle. The 6502 has an external clock and an internal clock. With a microcoded machine, states are traversed using edges on the clock. In each cycle, there are two edges so the microcoded machine can accomplish two sequential goals. An instruction like STA disp,x requires the following events: fetch disp from next byte in memory, add disp and x, store A in address calculated. At a macroscopic view, that's 3 events, but in actuality may be expanded to 6 or more events depending on how the chip was put together. So that's a minimum of say 3 external cycles if both edges are used or 6 external cycles if a single edge is used. Anyway, the point I'm making is that cycle times are totally irrelevant. What counts is the *time* to accomplish a task. > the 68000 line BTW could get things done in halfcycles... A sign that either the 68k is using both edges in a cycle, is pipelining or is multiplying cycles internally. Again, irrelevant. > : As for a relocatable zero page, the Z80 doesn't need one 'cos it's index > : registers can access all of the 64K address range, unlike the hideous Though Z80 programmers stay away from them like the plague because they're slow. The index registers are a Z80 specific feature added to the 8080 architecture and required a fetch of two bytes to decode rather than the typical one. Most useful as a last resort or in compiler writing. > The 6502 can also access all the 64k of the address range... > The hideouse restriction dosn't exist... Page 0 has special preference over the rest of memory. It's much slower to access anything outside page 0. Not so on the Z80. > The problem is the way the 6502 talks to hardware as to how the > z80 talks to hardware... to the 6502 it's all memory... > The z80 talks to hardware sepreately from memory... That's not really a problem - it just prevents a real computer from making use of the full 64k space as memory.

The Z80 makes a distinction between port space and address space: you have 64k of both. You can hook up devices in memory like the 6502 if you want or put memory in port space if you want. Accesses from ports are slower though. > However the reason zero page is moot for the z80 > is becouse you MUST use a 64k adress every time... > the 6502 let you use a smaller adress to get to the zero page memory.. > so this is a Z80 problem.... The Z80 has a large (relatively speaking - we're not talking Pentiums or 68ks here) on chip register set where running variables are kept. MOS's thinking was that you don't need registers on chip if you have them in memory, especially faster memory like in page 0. Unfortunately, this means algorithms run slower on a 6502 because it needs to access variables in memory vs the Z80 where it gets them from on chip registers. The slower access to the entire 64k space on the 6502 is the reason why the 6502 performs much more slowly when dealing with large data structures that can't be had in page 0. > True.. at 8mzh a z80 can out do the fastets 6502 of 4mzh > (Setting aside the z180 z280 z380 z8 and 65c02 65c16 65c816 65c802 etc) > However thats only due to the z80s added fuctions > as the 6502 at 4mzh matches the z80 at 8mzh is pure bulk speed.. I disagree. See my other post and put in your rebuttal there. > What would serve the job better? > the 6502... easyer to build and a tad faster in bulk speed... I doubt easier. The Z80 would need the ram chip, rom chip and a single ttl chip for decoding between the two, similar to the 6502 I believe. The Z80 also has a nice built in refresh feature so if you add drams, you don't need all that special dram refresh logic and if you've ever designed that before, you'll know it's a chore that you can do without. One of the main selling points of the Z80 was its ease to build around. > now if you need a bulk prossesing aray system that acualy had \ > 16 megs of ram with mosterouse hardware > z80... > It would need to bank switch ram around to get to all 16 megs > but it would be easyer to develup a system for it > and it would run much faster than the 6502 at the same clock rate... It'd probably be just as easy for both. Only thing is, it would be nice if the 6502 separated i/o space and memory space to make use of the whole 64k.

VIC and the CPU share the bus by doing access on different phases of the system clock. There is a brief conflict every eight raster lines. Disabling VIC on a 64 will gain around 7% of speed if you're lucky, and the system clock is 1MHz. The 128 doesn't improve on this any. VIC freaks out when it is run at 2MHz and is thus usually disabled. The 80col screen is much slower and infintely more cumbersome than VIC, too -- I would hesitate to say it gives any speed advantage :). >No putdown on the z80s...

Right, hopefully this end this bit of the argument so we can down to the real stuff. The 6510 in the C64 runs at 1 Mhz The Z80 in the Speccy/CPC runs at ~3.5Mhz So multiplying the values you gave above for the 6510 by 3.5 to account for clock speed we find: Processor Min Average Max 6510 7 14 24.5 (ignoring quasi opcodes) Z80 4 7 ~23 So the Z80 is faster, unless some C64 owner wants to dispute the perfectly logical way in which these figures were produced.

I stand by the original statement 100%. I have said: "designing in high level graphics support is a bad idea ". By high level I mean things like defining how many sprites you have, how big they can be and at what resolution.

The original Z80 was not microcoded - it was hardwired, another reason for its speed advantage. This is nearly the fastest way on a Z80. You can slightly increase the speed by realizing the LDIR instruction tests if BC=0 after each LDI iteration. You could have for example done 100 LDIs instead or 10 loops of 10 LDIs. > If I were you, I would stick to the 8502.

Twice as many in the same time for same number of cycles? On your C128, the Z80 is run twice as fast so it goes through 2 cycles for each 6502 cycle. This means on your C128, the 6502 and the Z80 do the transfer IN THE SAME AMOUNT OF TIME, even though it's run at half rated speed. > ldx #49 > ldir lda tab1+50,x > sta tab2+50,x > lda tab1,x > sta tab2 > dex > bpl ldir Aren't you cheating a little, XMike? Does this really address the entire 64k space like the Z80 routine you gave or does it just do things in page 0? Looks to me like you're using an 8bit index register and 8 bit address offsets. And it's still slower than a 4MHz Z80 as that's twice as fast as your 2MHz Z80. > 2 bytes moved in 21 cycles or 10.5 cycles average. The overhead is 1 cycle. > See, already I have beat Z80 code.

It won't, but pushing registers on the bitmapped screen might be a fast way to put up sprites. > Even the fastest Z80 instructions can be beat. RRCA takes 4 cycles while > ROR takes 2 cycles. As said above, at same techonology level, the Z80 is clocked at least twice as fast and maybe four times - something I'll have to check. At twice as fast, these instructions run at the same speed. The Z80 gains significant speed advantage over the 6502 for these reasons: 1. A large number of registers on chip vs using page 0 as registers on the 6502. 2. Asymmetric instruction set: 6502 instructions are general which requires a homogenization of cycle lengths on chip. 3. The Z80 core is not microcoded. 4. The Z80 has 16 bit memory pointers and can access the full 64k memory area faster than the 6502. 5. Complex instructions on the Z80 which eliminate the need to perform many fetch cycles to accomplish the same task on either Z80 w/o using the instruction or the 6502 which has only simple instructions. This is an argument which probably reminds you of a CISC vs RISC debate, except the 6502 doesn't possess the advantages of a modern RISC so the debate has a rather clear outcome in this case. > You may think the z80 should be a lot faster, but really it is extremely > inefficient.

Yes, except the Z80 executes at least twice as many cycles in the same time as a 6502 at the same technology level (ie when they came out at the same time). Your 6502, being a microcoded device, will multiply the external clock several times and internally, your 2 cycle instructions may take 4 or eight internal cycles to complete. > The cycles of the 8502 are on average about 4 per instruction, and range > from 2 to 7 (or even 9 with undocumented opcodes).

We've already named several games which are much slower on the C64 because they require the CPU's speed to do them and can't be done using C64 hardware. > The difference for the cycle times is due to pipelining.

There is however a kind of prefetch. The Z80, in the early 80s, could easily make up for this speed advantage with complex instructions (where there's no instruction fetch for a long time) or its on board refresh generation which stole *no* CPU cycles. Today, SRAM is so cheap, you don't need to bother with DRAM and refresh. But it's still faster :-).

Today, SRAM is so cheap, you don't need to bother with Ram refresh in the C64 also is hidden. If memory serves me, it's executed 180 degrees out of phase with the 1Mhz system clock. Bout the only thing in the 64 that steals CPU time is the video display. In the 263 line display, 25 lines have time stolen from then, in the amount of 43 cycles out of each line. As such, 238 lines receive a full 64 cycles each, and 25 lines get only 21 cycles each. When running a Super CPU (the 20 MHz accellerator), some operations are able to get around this, by simply not needing to communicate with the C64'S slower bus. Normally when accessing the C64 bus, any time one of these 43 cycle occurances is encountered (they are called 'bad lines'), the processor has to stop and wait. Oh well. In a Super CPU equipped machine, it's possible to write a program that completely get'S around these bad lines, by simply not needing to communicate with the system bus. If for example you have a lot of number crunching to do, simply move your data into an area of memory that is not being mirrored (there are four configurations), and do your work there. Avoid I/O access until your operation is complete, and you see a full 20Mhz result. _/ _/ _/_/_/ _/_/ _/_/_/ _/_/ _/ _/_/ _/_/_/ _/_/_/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/_/ _/ _/ _/_/_/_/ _/ _/ _/_/ _/-'-'_/ _/ _/-' _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/_/_/ _/_/_/_/ _/ _/ _/_/_/ natedac@dfw.net -- Specializing in Digital Sound on your Commodore Using BitchX for the IRC Rules!! -- Do *YOU* have the best!?

Err, I can load a 60K game in under six seconds from disk (well, including the time the head takes for the head to track to the dir, and back to the start of the file, about ten to twenty seconds, but it's still faster). That's where most of the problem is stemming from. You're talking about C64's of the 1980's, we're *using* C64's of the 1990's. The basic machine remains the same, but it's a rare C64 that doesn't have disk and a fastload these days, both of mine do.

At the time when C64s and Spectrums were dominant, the C64 disk really was as slow as the Spectrum cassette player. I remember waiting to load games for 10 minutes on my friend's C64 system. > That's where most of the problem is stemming from.

If you want to to talk about present day hardware, you can compare your C64 disk drives to IBM PC drives, because the "Spectrum" disk controllers use PC drives. My system supports DD 5.25 and 3.5" drives which store 400k and 800k respectively. I load memory snapshots in 3seconds. > A few of the C64 users reading this are using > C64's connected to the internet. Anyone on comp.sys.sinclair doing that? Ten years ago I read news and did email on my ts2068 with a 300 baud modem. Understandably, 300 baud isn't quick enough today.

Err, unless there is something fundamentally different between the Speccy I used to use and the one you have, he's right. Take a green sprite and put it over a blue A on a black background and tell me what happens. If either the sprite, the A or the background changes colour you've failed.

If the programmer is having to get his hands dirty with calculating viewports, camera positions, matrix maths etc. then it's what I'd call true 3D. Something like Tau Ceti or Encounter, with a seriously limited camera viewpoint, and much less calculation going on (hell, it won't even need any matrices will it?), is really not the sort of thing we're talking about. But yes, it looks good anyway, and both Tau Ceti and Encounter are a blast ;) Interesting that Pete Cooke and Paul Woakes (I think that was his name?) both went on to do 'true' 3D stuff.

Remember that Pete Cooke wrote Ski Star 2000 for Richard Shepherd *before* he wrote Tau Ceti or any other 'psuedo-3D' game. (Well, both SS2K and Tau Ceti came out in the same year, anyway: 1985.) Ski Star was of course a true 3D offering in the sense that you're talking about. A slow skiing simulator on a Spectrum /isn't/ as boring as it sounds, amazingly enough! SS2K is a very polished piece of work.

I see exactly one comment above which implicitly refers to myself (since I'm a C64 programmer), and I would certainly hope it is not considered egotistical.

My interest is in the statements themselves. If a statement is true, then it is true. I happily stand by the statements I have made to date. As to being an eogist, it is extraordinarily rare for me to hear such a claim, and I take it as a compliment :). Now, I didn't really post this message just to respond to a few (more) trivial un-technical charges leveled against me. As is usual in these types of discussions, much is being said about what was previously said, i.e. about claims that I (or someone else) was making, or that the Spectrum postings were totally devoid of anything resembling meaningful technical content, that C-64 users are in fact among the most knowledgeable, brightest, wittiest, handsome, physically near- perfect ideals of the human species, and so on. When I was a child (moreso) we used to say in these arguments, "Well if you could look into a crystal ball, and see what I actually said...". No crystal ball is necessary here. I have saved 300 or so postings and placed them on my web page (or rather will, sometime this evening). It's a big file :). But, the great spring flamefest can now be preserved forever (modulo some of the earliest postings which, alas, did not survive, sniff!). -S http://stratus.esam.nwu.edu/~judd/fridge/ >Alvin From sjudd@nwu.edu Wed Jun 4 18:35:46 CDT 1997 Article: 68635 of comp.sys.cbm Path: news.acns.nwu.edu!merle!judd From: judd@merle.acns.nwu.edu (Stephen Judd) Newsgroups: comp.sys.sinclair,comp.sys.cbm,comp.emulators.cbm,comp.sys.amstrad.8bit Subject: Re: Spectrum Emulator for C64 Date: 4 Jun 1997 23:35:25 GMT Organization: Northwestern University, Evanston, IL Lines: 52 Message-ID: <5n4u3t$gg3@news.acns.nwu.edu> References: <337C5E94.388@actcom.co.il> <01bc6f79$486f2220$04b8de8b@w9622136> <5mvksv$rif@news.acns.nwu.edu> <01bc7126$447a6860$04b8de8b@w9622136> Reply-To: sjudd@nwu.edu (Stephen Judd) NNTP-Posting-Host: merle.acns.nwu.edu Xref: news.acns.nwu.edu comp.sys.sinclair:39182 comp.sys.cbm:68635 comp.emulators.cbm:21081 comp.sys.amstrad.8bit:6661 In article <01bc7126$447a6860$04b8de8b@w9622136>, Andrew Cadley wrote: >Stephen Judd wrote in article ><5mvksv$rif@news.acns.nwu.edu>... > >> I am quite happy to say that C-64 programmers at least are aware of >> the difference between cycles and cycles per second. > >That is something not obvious from the majority of their posts. You can tell a lot about a person by the way they interact with other people, for example the way they post and the way they respond. For instance, I am an optimist, and a great believer in the intelligence of the public at large. When I speak with people, I assume a certain level of perception on the part of the reader, and do not attempt to patronize them by stating the obvious. For instance, when I say a routine takes 30 cycles to complete, I assume that most folks are capable of adjusting the result to account for processor speed. I assume that any child of eight can do this in their head. Moreover, when something is unclear or ambiguous, I assume that any interested reader will ask for or suggest a clarification. I assume that they will not be so naive as to assume that I simply make statements without any substantial reasoning behind them. Are you suggesting that I should not make these assumptions? >logical way of comparing routines. Obviously if you just count cycles, the >C64 routine will appear to be faster. If you account for the speed So if I said "It's twenty km by car, but 5 km by bicycle" you would assume that I'm claiming that biking is faster than a Ferrari? What assumptions do _you_ make about someone's intelligence when speaking with them? Anyways, if you want to see what was actually said throughout the course of these so-called discussions, please visit my web page: http://stratus.esam.nwu.edu/~judd/fridge/ (Unfortunately I think I lost most of the classic comments about how hardware graphics capabilities make computers obsolete, etc.) -S BTW, if anyone out there has some Z80 algorithms or source code that would like a good home, I'd be happy to put them in The Fridge. >Andy
