Just to share some of the back-story on the c65-support vs MEGA65-support of the MEGA65 rom. Firstly, I was happy to see Bit Shifter's name on the rom chip 🙂 I take it as a good sign that c65 owners got some benefit from Bit Shifter's efforts 😄 I remember a time in the past, a few years back, when the MEGA65 discord community was discussing whether to focus on maintaining c65 support or focusing more on making use of the mega65's own capabilities. I think I remember Bit Shifter being very keen to make use of the mega65's hardware capabilities so that the rom could benefit from them, in both the saving of rom space (make the rom code smaller) and performance. (Up until that point, he had preserved a sense of c65-backward compatibility). He had held back from adding MEGA65-specific logic for quite a while, until things built up towards that discord conversation. I think by that point, at least batch1 of the MEGA65 was out in the wild, so it meant a larger community could benefit from those mega65-specific enhancements. On our discord, there were opinions moving in both directions, my gut feeling is that c65 owners would have preferred we keep assuring c65-compatibility, though many of the mega65 development team didn't own c65's, and a larger community of mega65 owners was taking shape, and so the decision was made to support the larger community that was growing. That being said, the mega65-project and Bit Shifter, did push forward the state of the c65 rom further, and that is still a good thing for c65 owners, as the label on Bo's rom chip shows. Could things be improved for c65-users? Potentially, though I feel like c65 owners would be the ones putting on their developer hats, cherry-picking parts of the latest rom they can benefit from, while omitting MEGA65-specific logic. Should MEGA65-developers of software consider c65 backwards compatibility? I guess it'll be up to each individual developer. I sense most will cater for the bigger MEGA65 audience. On the other hand, if a C65 developer wants to build a program and share it with the MEGA65 community, there's a good chance their work can be enjoyed by the MEGA65 community.

The MEGA dev guys are all really great, and I'm so thankful for their help in getting a less-buggy rom. Also, yea, your analysis of the 'biggest audience' situation is right-on, though I would also add that to even have a Chance at making C65 compatible software, they would probably want to downgrade their rom to something more like mine, and who would want to do that?

I have an even more rare prototype in my barn. I built prototypes for Commodore. Tom Hilltine was the head of R&D. I was given an NEC computer, like the TRS100, and a Commodore 64 and was told to take the display out and hook it up to the 64. The graphics of the 64 was about double the graphics of the display, so I put in a joy stick to move the window around so you could see the whole display. You could play games on it if you were fast at moving the joystick. They used it for a boardroom display and then gave it back to me.

You gotta admit: I admire his lack of enthusiasm with the topless image. I *HATE* when demosceners use clearly sexual images like that. Even in 2023, there's a lot of children who are interested in coding and pulling off incredible tricks on computers (look at the Raspberry Pi), but then you got sleazy people who put THAT on there, much to the disgust and anger of parents. It takes away the fun of the experience of checking out the incredible capabilities that are possible on the limited hardware. And for David to express mild disgust at the image shows How thoughtful he is to his audience, both the young and the old.

It even has a German labeling. Stating "Funkentstört", which translates as "fitted with noise supression". So it should not interfere with Radio or TV broadcasts or other devices that use radiocommunication. DBP is the Deutsche Bundespost, German Federal Post, which was responsible for such tests and certifications at that time. It was a public administration and privatised in 1995 and splitted into several companies like the Telekom, Deutsche Post and the Postbank.

All of the C65 machines were rough prototypes. There was never a fully finalised, production ready design, so what you see is really just a possible taste of what might have been. A few tweaks and changes could have made the final product very different. The C65 was another of CBM's poor decisions, alongside the C16, Plus 4, the C64 "games system", the Amiga 600, CD32 and arguably even the C128.

I see the similarities to the C128 but then this machine may have had the same issue like the C128 with the software library. Most developers would have stuck with the C64 since it had a much bigger base. In the end it never came out and the focus laid on the Amiga which was IMHO a good decision.
@grawman67 3 ай бұрын

@railsrust 3 ай бұрын
I wouldn't completely agree with that. I think a lot of the reason the C128 didn't get a lot of support is because it didn't really add much for developers to think of it as a different development platform. The C65 would have been a clear upgrade in terms of capability compared to the C128's lack thereof. It also didn't really come off as anything other than just a C64 with more ram and some weird video peripheral most people weren't going to use. People largely just saw it as a C64 with more ram. To shift the market into thinking it's something new, you just have to sell it as a new platform that *happens* to support the old software. Remember, the expectation was that the new computer would still support their old software. This is why the Amiga had a hard time taking off, it didn't have a software base to stand on, and thus had to start from scratch. This is also why the IBM PC/Compatibles had a huge leg up, they already had an established library of software that would still receive some amount of support going forward. The real problem for this machine is that it just came far too late with no enough additional capabilities to justify its existence. The SNES would likely have been far cheaper if all you wanted was a game machine, and it had comparable/better graphics with a much more sophisticated sound chip. Or if you wanted to game and do business, just get a PC.

@MaxQ10001 3 ай бұрын
You might be right about software support, but I'm not sure. Remember, the 128 mode was not much better than C64 mode. Just more RAM. The rest of the hardware was identical. When the A1200 came out, it was supported immediately. Because it was better. As programmers we are always looking for new stuff. Musicians would have loved the dual SID. And graphic designers would suddenly get more colors than on the Amiga. We do new stuff when it contributes to more fun. Using 128 mode was not contributing to more fun. Also, remember, the 128 was a more expensive big brother to the 64. The 65 would have replaced the 64, at the same price point.

Thanks for your review! To understand the thinking behind the C65 you have to know that Commodore chose a completely different approach: Instead of including a whole C64 in the computer like in the C128 and thus giving nearly 100% compatibility Commodore tried to establish the C64 as a platform instead. A platform which the C65 was built on. So the C65 was technically a computer based on the ideas and principles of the C64 (with VIC and SID although there a two SIDs and a newer VIC) and taken to the next level (and thus having Amiga-like features which was at the time a must). The C64 "mode" was not a built in C64 like in the C128 but a C64-like preset (like memory locations, CPU speed, resolution, etc.) on the C65. So when entering the C64-mode with "GO64" you get a C65 with a memory mapping of the C64. But you are still on a C65 with all its capabilities. You can access the additional colors, CPU speed, etc, within the C64 mode, if you want to. The C64 mode would have been more of a layer to easily port your existing software to the new computer and to enhance it there. Only the second goal was C64 compatibility (which was a primary goal on the C128). The MEGA team did a wonderful job of finishing the C65 and bringing this great idea into the next century. They corrected many mistakes Commodore made (like the C65 expansion port, which is not compatible to the C64, on the MEGA65 it is compatible) and adjusted some things to todays standards (like HDMI instead of RF - the purpose is the same: to connect the computer to a normal TV set and todays TV sets are on HDMI). Since the MEGA65 is FPGA-based you can run the MEGA as a 100% compabile C65 if you want to (just boot into a C65 core). However the MEGA65 (with a faster CPU, an even better VIC and 4 SIDs) is still fulfilling the promise of Commodore by making a computer which understands the C64 as the start of a platform which can be build upon. Actually a lot like todays PCs or yesterdays Apple II computers. It's a shame that they didn't do this back in 1985 instead of the C128.

Once you consider the cost of a each of those two systems, and with either original acessories (storage medium, crt monitor, 9-pin joysticks) or modern add-ons (floppy emulator, video adapter and maybe one of the more advanced cartridges like the Ultimate II+) It gets quite expensive. The you might consider instead getting a MiSTer FPGA that runs both a C64 and an Amiga 1200 core + many more computers, consoles and arcade machines. The Ultimate64 from Gedion's logic would be my choice if all I wanted was the perfect C64, but they are out of stock now. Software emulators might also be right for you. The C64 'VICE' emulator is really great and the Amiga has a few, like 'Amiga Forever' and 'WinUAE'.

Keep in mind, the 64C is a "cost reduced" model, meaning there are way fewer chips than the breadbin, and the mainboard itself is smaller, and Commodore manufactured its own chips and improved its fabrication processes over time. So even with reduced sales they could still make a profit at this late in the game.

Aah, I feel like the slowness of the graphics example was due to Commodore's choice of using bitplanes for the graphics modes used by BASIC's drawing routines. I guess they were aspiring to do graphics like the Amiga, but this added more load on the cpu. My gut feeling is, if you want to see the speed-win, avoid bitplanes, and stick with the old-school c64-bitmap-graphic modes instead. That path will have it's own challenges too, as the c65 rom's drawing routines are hard-coded to work with bitplanes only, so at the very least you'd have to write your own line-drawing routine in assembly and call it from basic. Perhaps with that sorted, you could then see the speed win the 3.5 MHz speed ought to provide :)

If it did, then yeah, could take the win there. One other potential win could be the C65's DAT, think it was trying to translate x,y coords into an address in that c64 8x8 char block space. Maybe that might have assisted, though I don't think the rom makes any use of DAT either. I believe the C65 Zed Yago demo made use of it?

The image would actually be 50 frames per second, as it is progressive scan. With interlaced you get 50 fields per second, where pairs of two fields (even scanlines and odd scanlines) make up a frame. So interlaced PAL would be 50 fields per second, and 25 frames per second. Most computers, including the C64, however, do not output an interlaced signal, so they output 50 frames per second, they have no concept of even/odd fields.

Thanks for demoing it, too bad Commodore was a little too late to release this. If they had preempted the Amiga with this like you said and instead set the default drive to 9 or higher or made it possible to disable the internal drive, then it would have been more C64 compatible since an external drive could be set to drive 8 which a large portion of the C64 diskette software expects.

In Europe it would have sold by truck loads in 1990. The C64 was still selling quite strong, at half price of the Amiga. The C65 was cheaper than the Amiga to produce. I think it would have become a huge hit, and probably I would have stayed on the 8 bit line instead of switching to the Amiga. If it had come out in 1987 or 88, even better, but that was not possible due to the limited resources Commodore had. 1990 would have been possible, because it was finally ready for production when it got cancelled.
@paul_boddie 2 ай бұрын
By the truck load when up against the consoles? I doubt it. Even the low-end Amiga machines were effectively sunk by the emergence of a new generation of consoles, and things like the Sega Master System were quite capable of competing against an enhanced C64 like this. And although people may insist that buyers were using the C64 and Amiga for other things, the gaming market was where the volume was.

@@paul_boddie the technical capabilities of a system do not directly translate to sales numbers. When I say that the C64 was a big seller, together with the Amiga 500, in Scandinavia in 1990, it's not something I think. It's something I know because it was my youth, I lived there, I was active in the demo scene and I worked part time at a small computer store. We got the machines by the pallet. And yes, most people used them to play games. Free games. Pirating was huge. You could buy a NES or SNES and afford a few games, or buy a C64 or an Amiga, and have unlimited numbers. Also, new games kept coming to the C64 until 1991. If the C65 had replaced the C64 in 1990, at the same price point, it would have sold a lot.
@paul_boddie 2 ай бұрын
@@MaxQ10001 I don't disbelieve you that machines like the C64 sold well enough into the 1990s. I mean, Amstrad were also still selling various 8-bit models in probably healthy numbers at the start of the 1990s as well, including the tape-based ZX Spectrum +2. But I would have to ask what kind of pricing the C64 had to be able to sell by the pallet, as well as what software was being offered. Big retailers don't shift machines by appealing to piracy: Amstrad were able to keep on selling older models precisely because there was a glut of low-cost games, not because someone had some mates with a bunch of cracked games. And getting a presence at big retailers was crucial. It doesn't matter how many machines small stores shift if the competition is shifting orders of magnitude more units through the big retailers. There is also the matter of whether the C65 would have been able to launch at the right price point, which is as a budget machine priced to replace the already discounted C64. Commodore tried to appeal to the emerging console market with the C64GS at £99 which was a failure. Interestingly, in the UK, Amstrad released its own GX4000 console at the same time and at the same price, alongside other machines that were compatible and that might have broadened the market for enhanced titles alongside existing ones. That didn't work out either. The C65 (like Amstrads refreshed CPC models) would have avoided the usability issues of the C64GS, but it might have been a challenge to get the pricing low enough by including a disk drive. The budget-level ZX Spectrum +3 only got as cheap as around £200. Then there would have needed to be a commercial incentive to release software on disk, including new software taking advantage of the new features, as opposed to random "warez" peddlers copying other people's older games. Otherwise, they might as well have just kept on selling the C64. And I am very much aware that the low-end Amiga models did pretty well across the whole of western Europe, making people in Europe believe that they were somehow also very popular in the US. In practice, the European part of Commodore was probably shoring up the whole company in the end. But Commodore was stuggling to maintain volumes as the 1990s progressed and clearly trying to find a viable business strategy, hence all the different products they released that were not successful. And a substantial reason for that competitive hardship was the emergence of the likes of Sega who were making substantial inroads by 1990. Although you had to buy cartridges, there were probably healthy second-hand/pre-owned and rental markets already established in various countries. I guess we just see things differently, but I just don't see how Commodore would have been able to make the numbers add up.

@@paul_boddie I have read that the chip cost of the C65 was about the same as the C64. It had a higher BOM due to the disk drive, but a C65 would have been cheaper than the C64 with a drive but a few quid more expensive than a C64 with datasette. The big problem for Commodore I guess was that the graphics could be better than on the Amiga. With the optimized 6502, using 40-50% less clock cycles, and running at a higher clock, and with the included blitter, and 512 color capacity, many games would have looked better on the C65. The 68000 spent many clock cycles on some operations. The whole company was so mismanaged, the C65 should have been out in 88, and the A1200 in 89-90. But I still believe the C65 in 90 would have extended the rope they used to end themselves with, at least with a few meters. The 64GS was a catastrophy. I think we sold 4-5, and returned the rest. On one of the cartridges we got in, one if the games required you to press a key on the keyboard to start the game. No one had even tried to play it on the GS before release. That is saying a lot on how much energy got into that project. Had the GS used the C65 chipset with more colors and a blitter, it would have been a good competition for Nintendo and Sega. The only thing the C64 had going for it at that time was price. Cheap computer, "free" games. But, yeah, games were still being made. Can't remember the titles, but we got in new titles on a regular basis in 89-90.
@paul_boddie 2 ай бұрын
@@MaxQ10001 I would hope that they might have been able to optimise not only the cost of the system with the disk drive but also the way the disk drive worked. Watching videos showing the classic Commodore drives loading software, and recalling complaints from back in the day, the disk solution for the C64 was an absolute joke compared to other systems. But I think that to give Commodore enough room below the Amiga, if launching such a product as late as 1990, it would have to be aiming for £150 at most. (Note that Amstrad's systems which were a bit more expensive came with monitors.) Maybe that price might have made it viable simply as a cost-optimised C64, which was probably well cost-optimised already, but whose disk drive had not been similarly cost-optimised and refined. That leads to the issue of whether it would have been worth enhancing the system or just pressing on with the C64. If the chipset enhancements could have been incorporated effectively for free, with no expectation that anyone would use them, then I suppose the C64 could have been retired in favour of the C65. However, Commodore really needed to be cultivating new opportunities, and this would have needed developers to be actively involved in releasing new, enhanced titles, growing this as a new platform. There was little prospect of that happening by then since the big developers had been shifting focus for quite some time already. And selling lots of units on the basis of old game availability was all very well, but it would never have produced the volumes that such low-margin products need to in order to boost the company's bottom line significantly. I found it interesting that Mr Murray talks about the Apple IIGS as a comparable product when it arrived much earlier, as he notes, and has a 16-bit CPU, not the 8-bit CPU of this model. Admittedly, the IIGS was expensive, as Apple products were, but I think that any such follow-up to the C64 needed to arrive quite a bit earlier, as you suggest. At that point, there might have been a bit more developer interest. It is also interesting that you note the 68000 needing more cycles for some of its instructions to complete, and Mr Murray appears to be under the impression that a fast 6502 is competitive with the Amiga. Amusingly, Amiga enthusiasts were prone to complain about such observations when made by users of other 6502-based platforms, and justifiably so. However, they also made much of the illegitimacy of instructions-per-second ratings, how the Amiga was unfairly portrayed against things like the ARM, and so on, when all along the ratings were using industry standard VAX-comparable performance measurements and had nothing to do with the actual instructions.

It seems like every source covering this thing just keeps parroting the "16 bit" line based on the assumption that a machine like this would have *had* to have been based on the 65816, ala the IIgs. Strictly speaking there are *traces* of 16 bit-ishness on this CPU compared to the plain 6502; unlike it the stack can be relocated anywhere in the 16 bit address space, and they added 16 bit relative jumps and 16 bit inc/dec/shift operations. But if this makes this CPU "16 bit" then we should also probably be calling the 8080 and Z80 16 bit CPUs.
@paul_boddie 2 ай бұрын
@@PaleozoicPCs Well, the introduction of the B register and the possibility of relocating what had been only "zero page", plus stack relocation and a global stack larger than a single page, only really allow the CPU to make use of a single 16-bit address space. As you note, that probably only brings it into line with other 8-bit CPUs. Contrast that with something like the Z8000 where individual segments each occupied a 16-bit address space, and we see the difference between what is still in practice an 8-bit CPU (the 65CE02) and a classic 16-bit CPU (the Z8000). All the arguments over the years about whether something is 16-bit or not tend to drag products into that category unjustifiably. In reality, the 16-bit category is pretty narrow and things like the 68000 are architecturally 32-bit, even if they have reduced addressing capabilities and data bus widths, largely for cost reasons.
@PaleozoicPCs 2 ай бұрын
@@paul_boddie yeah… I mean, the “bit count” that gets assigned to a CPU can be pretty arbitrary and there’s a lot of gray area when it comes to making the call; it is data bus width, register layout, some combination of those things, whatever. If you go by register width you can make a pretty good case for even the Intel 8080 being *kinda* 16 bit; its accumulator is 8 bits but there are a subset of operations that let you use the HL register pair as a pseudo-accumulator, and it supports a fair number of 16 bit operations, etc. Intel called it “8-bit” because that’s what it’s data bus width was, its code is byte aligned instead of word aligned, etc… but there are “16 bit” CPUs (like the 8086) that tolerate byte alignment, and then of course with the 8088 you had the trend of CPUs that have an “architecture” wider than their physical bus, so that wasn’t considered definitive anymore… etc. So, sure, it’s not really an easy call unless you’re restricting yourself to truly “definitive” 16-bitters like the PDP-11, TMS9900, Z8000, and so on. But, really, as already pointed out, unless you go with address bus width there is basically no amount of wishful thinking that gets the 4510 into the “16 bit” category. The stack pointer is bigger, but the indexes and accumulator are all still 8-bit and its extremely limited set of 16 bit data operations are limited to memory words. It’s still way less “16 bit” than most other common “8-bit” cpus. Someone really needs to expunge this misconception from C65 lore. It definitely would have made sense to use a 65816 derivative, but that’s not what they did.
