I had an SX64 too but recently. I couldn’t afford one back in the day! I grew up with an Apple 2e but always wanted a Commodore 64.

I have a friend who used the C64 as his main computer up to the point his mom got him a Mac Classic and an HP Deskwriter for his birthday. We were both in a Doctor Who fan club in Southern California (way before anyone in America knew what Doctor Who was) and the club had an Amateur Press Association or APA. It’s like a club zine; everyone in the APA would type up a few pages, copy or print up however many they needed to contribute, in our case 8-10 each month, bring them to the meetings, then collate them together and distribute the zines to the members. My friend did his in GEOPublish. In order to get a physical copy he would send the GEOPublish service his floppy disc with the files, they would laser print it and send him the hard copy and his disc back. As a desktop publishing platform, GEOPublish rocked. His output looked just as good as the stuff i was doing on my SE/30 at work (I didn’t have my own Mac yet either). If my friend had managed a SuperCPU back in the day, I think he could have limped along until he could afford a better Mac on his own hook, but the sad thing is the GEOPublish service shutdown shortly after that and there was no way for him to preserve the files in any other format other than hard copy and raw text. But, there’s a prime example of a productivity use case for the C64.

I was CMD fanboy back in the day. I had a C-128D, 1541II and 1581 with JiffyDos, CMD HD-40, RamLink with 16 megs and Hd serial cable, SwiftLink cartridge and CMD mouse that gave my system a real-clock. I subscribed to their magazine, too. I used GEOS-128 until about 2005. I had IBM compatibles since 1989 and got a Amiga 600 in 1993, but love using the C-128 more. CMD was the best! My Aprotek 2400 baud modem was my only non-CMD, non-Commodore peripheral.

GEOS was really fun like this! Unfortunately I didn’t have any more loose capital by the time the FD-2000 and SuperCPU were released. But for a few brief years, 8-bit computing felt like heaven.

Those little blue modems were nice but a Swiftlink or Turbo-232 cartridge with a high-speed modem was really nice.

My C64 was my main computer for productivity well into the early 90s, because as much as I wanted an Amiga I couldn’t afford one. I used GEOS 64 as my office suite, and also used a terminal programme for getting online (with local BBSs, as there was a vibrant board scene where I loved). I did also play games on my C64, but I spent more time doing productivity and online communication. I remember reading Compute!’s Gazette about all sorts of cool C64 upgrades like this that I couldn’t afford.

Re still using old/obsolete hardware - I was still using an IBM XT in 1995. As a family we had a much faster computer that I was able to go on the Internet or play games on, but we kept our decade-old XT running and I had it in my bedroom so I could type documents for school in WordPerfect. :) It was the 90's equivalent of giving your kid a tablet or chromebook today

I really was a shameless power-user as a teenager. I went from my yearned for and saved up for 2 years Commodore 64 in 1985 to an Amiga 500 in 1988 to a 386DX-40 PC clone in early 1992. I was chuckling at my friends who stuck with the 64 and were trying to show off GEOS to me (which really was amazing in hindsight) when I was rocking WorkBench 1.3, and was enraged at the slow pace of Commodore R&D letting the PC clones get ahead of them with 32 bit CPUs and 256 colour VGA graphics that I jumped ship to PC land after comparing games like Wolfenstein 3D and Wing Commander to the by then completely outclassed Amiga offerings. I kinda wished I had slowed down to smell the roses then, there's a lot of satisfaction to be gained by eking the most out of limited systems and pushing them beyond those limits. I love videos like this. I would love to have seen Mercenary: Escape from Targ running on a 20MHz C64!

I was one of those people who ended up using a Commodore 64 long after the expected expiration date. But part of that was lack of alternatives, and there's no way I could have afforded an accelerator device that cost as much as the machine itself. I really wish I had had one though.

What about the Amiga..

I remember seeing the SuperCPU advertised, but I didn't buy one. By then, I'd moved on to the C128, and the Amiga, before Windows 95 ushered in the internet for me. I'd fiddled with bulletin boards a little on my Amiga before 1995. But, my first IBM compatible was an AT&T Globalist in 1995. I recently received my The C64 Maxi, and am having a good time with it, refreshing my memories that have faded over the past three decades or so. I was never much into games, but more into seeing what I could figure out in the programming department, and that's why I bought the The C64. There were really only two games I spent any time with on my original C64s; Jumpman and Fort Apocalypse. And I saw end screens for both of them. The primary game I played on my Amigas was Test Drive II. I actually, physically broke a joystick on that game trying to make a curve.

Oh, damn, didn't realise this came out in 1996. I was thinking what an amazing product it was with the w65c816 and 16MB of RAM, and all the awesome things you could do with that, what with zero (direct) page relocation, stack relocation and a 16 bit stack pointer not bound to a particular page boundaries, stack relative addressing, but then I remembered all the things I was doing on a PC in 1996 ._.

@jjeeeekk

3 жыл бұрын

Everything with some minor limitations. Stack and Direct Page is bound to bank 0, the Direct Page not page-aligned demands 1 extra cycle (e.g. for usage as high-level language frame-pointer). ;)

I had never heard of the SuperCPU before. Nevertheless I want to recognize the time and effort that went into making this video. You left no stone unturned. Excellent.

I was still buying brand new games for my C64 from my local Electronics Boutique as late as 1994, when apparently corporate told them to reclaim that shelf space. That was the year I graduated high school and the year an article appeared in my local paper, The Mercury, saying local business Commodore Business Machines was filing for bankruptcy. That article hung on my bedroom door for 10+ years. Had I known then that CBM was only 30 minutes away from me, I would have have visited. But that is hindsight. I didn’t even bother to get my driver’s license until 1994. Sigh... memories.

Still not an Amiga or 486 by a long shot but seeing GeoPaint running that smooth and Metal Dust on that C64 blew me away. Not that there were stunning things happening on stock hardware before but this SuperCPU stuff is in a league on its own.

When I bought my first 486/33 after college, I got rid of my C-64. I learned later the freeze ups and reliability issues it had would've been solved if I knew where to buy a replacement power supply. Sounds like the SuperCPU was a great product, but just a little late to the market

Awesome video, Robin! Where I think the SuperCPU really shined was amongst the diehard C64/128 users in North America that refused to switch to anything else, even as Commodore shriveled up and died and software developers vanished from the platform. These are people for whom Commodore was a way of life, something they used every day, and were often not gamers. These were the guys who were LOADSTAR subscribers 'til the very end. I think we all knew people, primarily older folks, that used the C64 or C128 as their primary computer well into the late-2000s (what is that, the aughts?), and the SuperCPU (and other CMD hardware) made stuff like GEOS useable enough to actually perform work and do tasks with (though GEOS 128, in 80 column mode, with an REU and a CMD HD (or even just a 1581), was also a very usable platform even without acceleration). Many people did just that, really, using their Commodore rigs for day-to-day stuff until the internet arrived. Specifically the web, because even I used to use my C128 to send email for a number of years. Even the mighty SuperCPU couldn't compete with the web, unfortunately. I also feel like that's why there's such a dearth of these remaining, despite several thousand of them being built and sold: a lot of them stayed with their older Commodore users and, when those users were no longer with us, they ended up getting lost or thrown out by family or estate liquidators or whoever does that sort of thing, to the point where there's a handful left, all of which command preposterous prices on eBay. Anyway... TL;DR: Where the SuperCPU did succeed was that it helped Commodore users (not gamers, not developers, just regular ol' users) keep chugging along into the new millennium. AJH

My ideal setup was to run my C64c with a SuperCPU, SwiftLink and appropriate modem, an FD2000 and CMD hard drive. I remember debating with my friends in 1996 on how this could keep up with PCs and Macs of the time, but I was always stumped by the software support problem.

Would be good to get someone from CMD/Berkeley Softworks on a future episode as a retrospective on the impact their products had.

Cross Assembler, i remember building a parallel port to userport cable back in '96 or '97. The userport's D0--D7 weren't able to drive the printer port directly but it worked vice versa. IIRC there was one line from the userport to the (i think it was) paper sense line (or something) that i used for a very dirty handshake. Wrote the transfer program in QBasic on the PC and in Assembly in the C-128's built in monitor. Worked like a charm. Made it so it would boot and wait in the background for the transfer to start. After the transfer was complete, the receiver routine wound just jump to that new program.

My former co-worker ran a 128-based BBS for our user's group as far as the mid 2000's. His C128D had the Super CPU, some CMD drives including a CMD HD and JiffyDOS-equippped 1571 drives. It's sad how all the old CMD stuff sort of evaporated when the then-owner was going through some drama that I don't know the full story on. I believe that a Turbo232 and a CMD RAM-Link were also part of his setup. He was also a big GEOS fan. He also played with the GEOS-based web browser...

I absolutely LOVE slang, but the problem is as soon as I tried to use it in any serious way I found it had show-stopping bugs. I still think there's desire by people that own these SuperCPUs to have a dev kit. At least I would! If you do ever finish a SuperCPU game, I am buying it! FWIW, there's also Wolfenstein 3D for the SuperCPU. I have run it. It's very strange to see it run on a C64. That should count as a second game for it. I wonder if we could petition for a C64+SuperCPU mode in the upcoming Mega65...

It's not ... one of the amazing things about the Commodore community is how they stuck to the original setup (c64 + 1541) for a long, long time ... well reaching past 2010. I know 4 people who own a SCPU and one of the devs for one of the very few pieces of software specifically designed for this accelerator. Never even cared about asking if I could have a SCPU on loan. If you want hardware expanded beyond any reasonability better go with the Amiga or Atari XL lines.

That is a cool bit of kit, silky smooth performance on the stuff you demoed. Also seeing the Altera in the prototype begs the question, maybe a 2020's update based on an FPGA (or a Pi)? That would be hilariously fast. 🤓😁

Just subscribed to your channel! I really enjoy the technical and depth content you have here. Thank you!

CMD was a great company. I had their RS232 addon that let me uses a 2400 modem back in the day (connected to the local college VAX...amusing trying to tweak things that were written for 72 or 80 columns to run on 40-col. Did try the 80-column terminal program that came with the adapter..NovaTerm, I think it was?...but since I was using a TV rather than a monitor, it looked too aweful to read) Also, I remember reading somewhere..BYTE magazine, perhaps?...about someone who had made an expansion-port board that allowed them to run an enviromental control system via the C64 (lights, thermostat, and such) for an office building. It always amazed me just how well-documented the C64 was, for both hardware and software..you could do things with it that were very obfuscated on the PC side of things. And are even more so these days. Edit: Oh man, the quiet 'chuckling' of the disk drive as the stuff loaded...even if it was a 3.5" rather than a 5.25"...talk about a serious hit to the nostalgia. :-)

It's very impressive! Can you imagine if we had this back in like 85 or 86? It might have made some of us put off moving up to 16 bit systems.

18:04 that part of the credits is about the release of a remix of the soundtrack on an album which has a weird title: "Nur tote Frauen sind schön" which translates to "Only dead women are beautiful".

I didn't know anything like this existed at this time, or that people were still using Commodore 64s. My family upgraded from c64 to a 486 in 1995, and I thought we were one of the last people still using Commodore 64s back then!

4:00 I had the Final Cartridge III. Man I loved it. It allowed me to hack several games with its built-in dis-/assembler.

It's mind bending to try to put this into the chronology of late '90s computing. I graduated high school in '96 and had already gone through many years with an A500 and a year or so with a 386 laptop by then. Those were both 16 MHz machines. A 20 MHz accelerator for a C64 would be a neat trick and the benefits for GEOS are obvious, but if my goofy kid self had already moved on years earlier, where would this live? (You address this, just sayin'. :) )

Great video, thanks for posting! The SuperCPU is very interesting!

This is really great work. Thanks for expanding my mind even just that amount!!! :D

I had a Commodore 64 as a child back in the mid 80's. Had a lot of memorable experiences with it. I used mine mainly for playing RPG'S like AD&D Pool or Radiance series and niche type games like Spy vs.Spy. By 91-92 the Commodore 64/128 had become dated. By 96 to 2000 Windows 95 and 98 had become the new rage in computing and although the SuperCPU was a great product that had plenty of potential had it come out years earlier, by 96 most people had moved on to PC's and the Commodore 64/128 was considered an old relic from the 80's.

I would have loved to own one of those back in the day. But, I upgraded to my Amiga and never looked back. I am surprised that did as well as it did to be honest. The Amiga 500 was pretty reasonably priced in the 90s (in Canada for me). I think of all computers I ever owned, my Amiga was the absolute best. I used to run a BBS on my C64, I wonder if that would have improved it. I had the same Super Snapshot you owned and loved it. It's how I learned to program assembly for it. Good times, I miss those days A LOT.

High quality content.. well done.. thx for sharing

I really enjoyed seeing what your 'daily driver' was. I'd love to hear more about how you used this setup in the 90's.

When I worked on IT in the 90s, I’d see obsolete machines all the time. Especially in factories which would have some proprietary equipment hooked to a c64, or apple 2, or cp1, etc, using proprietary software. They can’t replace the computer without replacing the machine.... so...

IMHO, the death of these machines was the lack of 80-column support. It's existence is fascinating however. Western Design Centre had an 8Mhz 65816 at launch I believe, which Apple didn't use because it would have threatened the Mac.

Out of all the things I bought for my C64 set up I wish I still had, I wish I still had my *CMD HD 20*

I'm interested in hearing more of your rants about "using what you have and know" vs always going for the latest and the greatest in technology. If you'd consider making a video about how you feel about the modern age of computing compared to when you were growing up, the in my opinion sad changes in how coding is done (each megahertz and megabyte costing fraction of a dollar and in turn coders tend to forgo any discipline for optimization) and so on; I'd be very interested. Keep up the good work.

CPU: "ok, lety's get-" (6502 steals a cycle) CPU: "AS I WAS SAY-" (6502 steals yet another cycle) CPU: *screams*

A fun fact.. this runs in 13-14 jiffies on a U64 in turbo mode :) The basic optimizations do not seem to make a difference.. the same value returns.

Excellent demonstration, thank you!

GEOS really benefited from the SuperCPU. Anyone who played Elite will remember that when another ship entered the system, it took forever to get to the space station.

20 MHz ???? Insane! What would you do with all of that processing power?

I bought Metal Dust just because of this demo... I don't have a SuperCPU, however it works well enough in VICE!

Another reason the SCPU failed was feedback on tech demos. The community want very impressed with these and told the scenes where to stick it and thus the releases were very few indeed. Maurice Randall promised an extended SCPU, a cartridge that would boot up on a C64 aswell as a C128. I would have loved to see that.

It's just an April Fool's joke I worked on but never did release :) The idea is that if a SuperCPU multiplies the C64 speed by 20x then a second SuperCPU would again multiply it by another 20x. I actually don't know what would happen if I plugged two in together like that, and I'm scared to try.

I gave away my C64 in I think 87 or 88 and bought a 1024 ST because it had 68000. I had no idea about JiffyDos or the SuperCPU were even made until a few months ago. I messed around with Assembler on the 6502 and then the 68000 and I can't imagine all the design hell of swapping mem in and out on the 6502. The SuperCPU is a great product but advancing technology killed it.

There were a lot of games back in the day that just need a little boost. Overclocking the Sega Genesis shows that pretty well. Hard Drivin' and Race Drivin' show that really well. At stock -7.16mhz they are just playable, overclock to 10 they are a lot smoother, and at 12 or so they are silk. I'd like to see Mercenary for the C64 on the SuperCPU.

This is one of those times I wish the Mega 65 wasn't so very, very expensive...

Thanks Robin! Takes me back to the old days! Did you ever run a BBS? The CMD SuperCPU would have rocked serving up telecommunications...

@8_Bit

I never did run a BBS but I know some people did run them on a SuperCPU. In fact, I think this one is STILL online: www.triad.se/antidote

You should try TopDesk/MegaPatch v3. it was the European alternative to Wheels, and quite a lot better. It had reasonable popularity in Germany and in the UK. I seem to recall a few more games that ran on that SuperCPU module. note that terminal software with a fast modem was reasonably boosted, particularly on the 128 with the appropriate CMD module.

I created my own expansion board that supported 8 cards. Each expansion slot had 2 switches. The 1st switch enabled/disabled the slot. The 2nd switch set the NMI or the IRQ (can’t remember) to reset the computer. When I plugged in a game cartridge and turned on the computer and pressed reset button, the computer would go to the run prompt, then I could save the cartridge to the disk.

That device is fascinating, but now I understand how and why IBM PC won the race: One size fits all...

C64s were also used for businesses in Europe quite a bit, especially in Germany. Yet, 1996 is really fairly late. That's Pentium MMX territory.

Every c64 video you post makes me happy

Must have been amazing for c64 users at the time when this was released. Jumped processing speed forward 10 years at the flick of a switch.

The Amiga 1000 was faster than this and was released only 3 years after the C64's release. The same year the SuperCPU was released you could buy a Pentium II 300 that was 20x faster.

Fascinating look at something I'd never heard of before.

crazy to make an addon for a computer like this 13 years later. It's def cool but also very head scratching.

Brilliant episode!

0:13 I mentioned before that I recycled an FD-4000 and an HD-200 the last time I moved. I also threw out a SuperCPU for the C64 and a SuperCPU for the C128. You're welcome! (That questionable choice makes yours more valuable!) 0:43 The 65816 just gives me heartburn, like the 3K gap in the VIC-20's RAM. They had the potential to make a great extension to the 6502, but they made several bad design choices that makes it painful to think about programming. E.g., they decided to make 8- and 16-bit operations into different CPU modes rather than different addressing modes. Consequently, you can't LDA #$1234 : STA var16 : LDA #$56 : STA var8 without awkwardly switching modes. You can't even disassemble this code without knowing what mode it's for. 3:38 I used the C128 as my main computer until 1996, when I switched to Linux. 4:21 You might be preaching to the choir. 6:45 Running Warp mode in VICE on my i7 desktop only gives the equivalent of 92 jiffies. Of course, its internal Jiffy timing gets messed up by the Warp mode. I wonder if VICE has a mode that speeds up the CPU without speeding up the I/O chips. 7:43 The direct speed-up factor between an unencumbered 1.023-MHz 6510 and the 20.000-MHz 65816 would be 19.55×. 9:38 You could also mention the C64 Super Mario Bros. game you made a video about. Did Nintendo ever drop the hammer on that? 9:49 What the heck? An Atari joystick with two fire buttons and a woodgrain finish? LGR would like it! 17:59 "This game is presented in BB Bolby Mono"! I guess that's like a Bolex watch that's a Certified Ceronometer. 24:44 I made sure my own programs were compatible with the SuperCPU, RAMLink, and CMD REU products, since that's what I had. 26:12 When you plug two SuperCPUs into each other like that, do you get 40 MHz or 400 MHz?! 26:24 Add video to the SuperCPU and you pretty much have a new computer. Around 1997, CMD contacted me about writing a multitasking operating system for their next 65816-based computer. I had to turn them down since I had just gotten the job that I still have today. They didn't tell me much, but they talked about Mensch Computer ( wdc65xx.com/mensch-computer-solid-state-computer/ ), so I guess it was going to be a similar idea: a solid-state battery-powered mobile computing device (why does that sound familiar?). I didn't hear anything about C64 compatibility. CMD sent me a third-party C cross-compiler that ran on DOS for the 65816 in that time frame, for the multitasking OS. The 65816 is much better suited to a C compiler than the 6502, with its 16-bit stack pointer and the stack-relative and stack-relative-indirect addressing modes. Also, the 16-bit Direct Page (zero page) can be used as the first 256 bytes of the current C stack frame for greater efficiency. 28:25 "We're living here in the future - 2001!"

Sorry for putting you through the trouble of updating your comments for the new edition :) That woodgrain joystick is a Hyperkin "Trooper" which was just made a couple years ago, I believe. It's pretty good. The buttons are wired together. Since the SuperCPU splits each CPU cycle into 20, plugging a second one in multiplies the effect, for an incredible 400 MHz. If only I owned a 3rd, I'd have a 8 GHz Commodore 64, I'm sure of it! That's amazing about CMD's planned computer. I wonder how far they got with the design.

A good video. The SuperCPU is an interesting product, bringing new life into an aging machine and helping a lot of users still relying on it. But it feels as if it's starting to become the Ship of Theseus. At what point is it no longer a Commodore 64?

@8_Bit

I get your point (and appreciate the Ship of Theseus reference), but as long as it's got the VIC-II, SID, and can run most C64 software, it's a Commodore 64 in my book :) Note that Commodore themselves shipped a far worse abomination shortly after the launch of the C64: the CP/M cartridge which committed the crime of putting a Z80 in charge of the C64's bus, and was hardly compatible with anything.

Amazing video! Thanks for uploading. Just a quick question: Would it be possible to scan and upload your version of the user guide somewhere? I also own a SuperCPU, same version as yours, which came with no manuals at all, and I was surprised of the POKEs you used to actually unleash the full throttle on the accelerator. Doing a Google search I only see PDF scans for the SCPU128 or SCPU 2.0 but nothing earlier. I'd love to have a look on the official users guide for this version. Thanks for reading this. :-)

Thanks for the video! In one of the ads for the SuperCPU, it compares the product to other apparent C64 boosting products. Were any of those available in the 80s? Was upgrading the CPU a thing during its heyday or did most folks just expect to completely switch computers at that time? Although I was a child of the 80's (and born in the 70's), my family couldn't afford to get a computer until the mid 90's so I mostly missed the c64 era.

Hi Roy! Those other C64 CPU accelerators were very uncommon. I didn't know of anyone with one at all, and when people outgrew the C64, they generally either bought an Amiga 500 or some type of IBM PC-compatible. I bought an Amiga 500, but still kept my C64 set up and running too, which was unusual.

@@8_Bit Thanks again. It seems like a golden missed opportunity for a mid-life refresh in the mid-80's. Something that boosted the c64 by a factor of x8 like your testing showed with your custom micro-program would have been appreciated likely at that point by both gamers and productivity users. I'll have to add that to my bucket list of things to do if I ever get a time machine. :)

I think it was Protovision (or GO64?) that create the Turbo Assembler for the 65816. Awesome feat of brilliance!

Well done video. I think I briefly saw something on your screen about a dual SuperCPU being enabled. Could you please give a little background on that? Thanks.

wow.. the idea of someone using a C64 as a daily driver in the later 90s is just wild to me. At around that time I was using a 233mhz Pentium 2 with 32MB ram and a 3D accelerator card... This is neat though, I had a C64 in the 80s/early 90s. Kinda wish I could find one again for old times' sake.

I'd be curious to see what demos run partially on this thing and what the crashes look like

27:02 I realize this video is older but in the last few months I believe some information was revealed that part of why the 32X was released was some serious resentment from Sega of Japan to Sega of America. It's way off the topic of this video but is unbelievable yet is too fitting for explaining how Sega could rise and fall so fast in the home console market.

Sega never had a successful console in the U.S. other than the Genesis. But that's normal - Atari only had 1 successful console, the 2600. Nintendo's first console dominated the market, but they lost that position and never regained it. Microsoft lost money on their first 2 consoles. Sony is really the only company that's had consistent success.

We've just been discussing it on the lemon64 forum- specifically people wanting to clone it and add new features with fpga. The obstacle seems to be finding the logic paths of the cpld. Aside from slicing the top off and looking (unthinkable unless someone owns a broken device), do you think it would be possible with a logic analyser?
