Can you build a brand new Commodore 64 from (nearly) 100% new parts?

[@JVHShack]

As far as I know, there are modern replacements for nearly all of the Commodore custom chips now. You may want to look into seeking them out for a later video.

[@djcsdy2]

@@TheRetroShack Looking forward to that! I have my doubts that anyone could make a 100% compatible VIC-II clone* what with all the weird timing bugs that the whole demoscene and plenty of games rely on, but it's not something I've been following recently so I hope to be pleasantly surprised :-). *An ARM chip running a VIC-II emulator in software doesn't count! 🙂

[@stefanweilhartner4415]

@@djcsdy2 it "just" a matter of thorough debugging. regarding these timing issues, it is possible to write software that exactly constructs these corner cases. usually it has something to do with ending or starting a line or writing into a sprite register shortly around the time where the sprite is displayed. it is not magic but thorough work and trying to find all corner cases. you have all the registers and have to find out the time where writing to the register results in an update. one example: changing the color of a sprite: does it work in the middle of a sprite, does it work only before the sprite is painted, what delay do you have when the first pixel in the line has already been drawn. it is a huge amount of work to write and check all these (corner) cases. but it can be done. especially when changing a lot in the VHDL code, you have to run these tests again.

[@djcsdy2]

@@stefanweilhartner4415 That's true, but what I was trying to get at is that there may still be unknown unknowns. It's not that long ago that demos were coming out all the time that relied on some newly discovered quirk, and emulators which previously supported every known piece of software would have to be updated to support the newly discovered behaviour. I haven't been following the scene closely in nearly ten years, so for all I know that hasn't happened for a long time, but the scene is still active and I wouldn't like to place any bets that there aren't any quirks left undiscovered. To be absolutely sure you'd have to decap a VIC-II and transcribe its design into a formal proof. As far as I know nobody has done that but I could be wrong. I have written code to exploit timing-sensitive bugs on the C64 myself (DMA Delay scrolling, etc) so I do have some idea what I'm talking about although I might be out of date! 🙂

[@chrisbranson1490]

Great project - When I did mine I used a SixtyClone 250466 as this rev uses the original bread bin SID and VIC-II but benefits from having only the two RAM ICs. With the same aim as using as many new parts as possible I also used the c0pperdragon RF board which gives a much improved video out, ARMSID and GAL based PLA - I also put in a SaRuMan static RAM board and Tolb 8701 replacement, and burnt my own ROM chips for Basic, Kernal and Char. The CPU, CIAs and VIC-II were all salvaged parts as there were no other choices.

[@TheRetroShack]

The plan was to use more homebrew chips but some aren’t available yet as you say, and the kernel and char roms I ordered didn’t turn up in time so they’ll be in the next episode :)

I bought the original ZX80 kit and built it at school in my Technology class and after building it it did not work, both me and my teacher tried to problem search it without success ( we suspected a faulty Z80) so I sent it to Sinclair for repair and they sent a brand new kit back with no explanation or paperwork and about 3 weeks later my original build came back working as well, I loved that little thing!

Great video, there is something quite magical about building your own C64 board! I've recently put together an 250466 SixtyClone board (in glorious purple!) and I too used the Retro8BITshop kit of parts. My build uses a few replica parts like a J-PLA, NanoSwinSID, a SauRuMan64 RAM module and a TEBL Modulator Replacement PCB. For my ROM chips I am using CornBit V2 from BackBit. I also went for a RECOM Switching 5V regulator in place of the 7805, it runs a lot cooler... no need for a heatsink. My original BreadBin machine uses the less common KU-14194HB board of which Bwack has also made a replica.

[@KRAFTWERK2K6]

Oh this is fantastic. I really feel like wanting to put together one as well to celebrate the 40th Anniversary of the C64 by giving birth to a very very personal handcrafted C64. Simply because this was the first homecomputer i ever had the privilege to get in touch with as a kid and playing Maniac Mansion and Epyx Winter Games on it together with my father. I just HAVE to do it. Thank you for doing this and showing every step.

3D printed pieces are fine if you take the time to prep and finish. I sculpt/model up ideas, figures, diorama pieces, etc in Blender before diving into hand sculpting using the 3D piece as reference or just straight printing the pieces out either with filament or resin. Coming from doing a lot of auto body work, the newer filament printers are high enough resolution to get a smooth line new finish without a lot of prep work (basically filler into sanding, on primarily flat or straight-line shapes if printed at high resolution you can get away with 2 coats of primer/filler paint after initial sanding, first coat, wet sand, second coat, wet sand, then go for a final into paint). The only time I default to resin is if there's a lot of tucked away details making proper finishing a paint. Not to say you shouldn't prep resin prints too, they're definitely cleaner and higher resolution, but there's still room for improvement (especially drainage holes if those aren't hidden when assembled). If typically create molds with my pieces after achieving the proper surface and finally casting the final piece. Not really required for a one off, but if you're planning on doing even a limited run of figures or something it's a lot simpler to just cast them for a consistent end result over printing and finishing each (not to mention faster).

Solder type or screw type D-Sub (Joystick Port) Nowadays PCBs are mass populated and leaded components are soldered in one move using a process called reflow, which is a standing wave of moltent solder that skims the bottom of the board as the board passes above. This gives all leads and pins a perfect solder. The problem however, is if you have a connector attached with screws, solder often gets into the grooves of the head or alternatively the threads if the screws are fitted the other way round. However, if you opt to fix the screws at the end of production, then solder often gets drawn between the connector and board often making it near impossible to install screws. This is circumvented with using either clipdown connectors, which fare well against the hot molten solder for the brief time it skims across the standing wave, or the solder type, which is my favourite as it offers better grounding for when you need shielding in your cable, such as in DVI or VGA or HDMI connectors. It was never introduced as a time saver, however it has given that result.

[@1kreature]

Technically snipping the leads after soldering can stress the joints. Ideally one would fit and clip the leads before soldering. I'm enjoying this vid to no end! Thanks!

What's available: the 6502 is available as the 65C02, but the required 6510 is only available as the original C=. There are replacements for the SID and logic array. But not for the two CIA. For the video IC there might be a replacement with a raspberry pi zerro, I'm not sure. Is dynamic RAM still made in this size? The ROM can be replaced by an EEPROM, but has a slightly different pinout. But if a Raspi is already on the parts list, you can emulate it.

[@uliwitness]

I had hoped this would be more about the hunting down and picking modern parts. Any chance of a future video where you actually source readily available stock parts and track down replacements (like FPGAs or whatever) for the special chips?

is it possible to have a fastload cart built into one of the ROMs? Maybe install some sort of ultimate loader that has all your carts, and disk images already inside the unit on an SDcard, while still having outward compatibility for a physical cart, printers and disk drives?

My first computer was a Commodore Vic 20 because my parents could not afford the 64. That is where I learned to type, I still remember the Space Invaders inspired typing game to this day. Then I graduated to a Tandy 1000 and I thought I was in heaven.

I don't know what the fuck is going on but I'm impressed.

Would be nice to see a console built like this too! An NES/Famicom maybe. UMC's clone chips are readily available.

Now you've got me thinking!

I have an old Commodore 64c “Test pilot” kit, an extra floppy disk drive, and several programs. What’s it worth? Not sure if it all powers up. I haven’t set it up since I left Germany in 1992.

Why sockets over soldering the chips to the board? Ease of repair? Or does soldering some chips cause damage?

[@TheRetroShack]

Simply for ease of replacement in case there's an issue :)

Awesome video!!!! Great work and great explainations 😃😃😃

If you're looking into making a new custom case, you should stick to the black theme... i got a feeling that a black case would look awesome.. maybe with backlit keys

[@TheRetroShack]

Watch this space! :)

[@ro63rto]

Still have mine in the attic. Time for a nostalgic gaming session I think .

[@TheRetroShack]

Go for it - If you've got Thing On A Spring it's one of my favourites! :)

I was an early adopter of the Vic20 and C64, I even went to several electronic schools. I owned, traded, enjoyed, played yarda yarda yarda but to me this is like building an old push lawnmower and using it. I must be wrong though, or these raw pcb's would not be produced so, I guess there is a huge rush to build and own a completely obsolete play computer. Thanks for the vid. You are very good. //ji

Hard to believe compact disc hit the scene around the same time as this board

[@ldchappell1]

Even though CD players were available in the US as early as March 1983, the average $1,000 price tag made them unaffordable for most. Two years after becoming available, only 1 in 600 American consumers owned a CD player. I paid $239 for a Sony Discman in 1988. By 1991 they were putting CD players in $80 boom boxes.

People might ask what is the point of building a brand new model of a computer from ~40 years ago. Well, people also build model airplanes, cars, ships, starships, etc. This isn't much different, and it actually has a function that people can explore.

[@TheRetroShack]

Absolutely! Good point, well made :)

Don't forget to install the Faraday cage around the clock. It's not needed for the RF Modulator, since you're using a digital out.
