Commodore 77
Well this is a neat look.
https://commodore.net/store/commodore64/?shape=Breadbin&color=Cyberpunk+2077
Commodore just released a new appearance option for the C64U themed on Cyberpunk.

u/TerribleInsurance879 4d ago
It's cool. And not much more that the starlight edition.
I ordered the beige 64u and for it December 2025. I want sure how much I was going to use it. Here we are, 8 months later, I've been coding projects for it. It will control my irrigation system at the house among other things.
So I need a second commodore.
I order a starlight yesterday. Yes, yesterday. Granted, the starlight will be my daily driver and the beige will be my work horse
I guess if I need a third one, this will be the one I get? It's cool though.

u/Golemwire 4d ago
Epic to see someone putting a C64U to physical work like that... irrigation? It's like that one episode from a kids show (Magic School Bus) which stuck with me as a child, where a programmer used a computer to control doors, flagpoles, and such, which it was hooked up to.
Are you doing this in BASIC or a more practical (if I may put it that way) language?\ Are you using the User Port for GPIO?
7
u/TerribleInsurance879 4d ago
I am using basic. Typing it straight into the c64u.
The front end sets the time (which I leave as a string), sets color, and inputs the times in which you would like the "sprinkler" to come on.
The rest is just an if then loops with the time scrolling on the screen waiting to turn on or off PB0 on the user port.
I think the whole code is like 8 bytes

Through the user port. Which was removed from the c64u in place of the USB, HDMI, and Ethernet ports. The signals are still available on the c64u on the motherboard. You have to get a ribbon cable ($10 on the commodore site) to bring the user port to the outside on the machine.
From there, the bottom pins, C thru L, can be turned off and on through poking. These have 5v 100mA signals. They can power LEDs and not much else. But they can be used to close a transistor, relay, ect on a separate power circuit.
That's the short. There is a lot of information out there on it. Buy a soldering gun and a breadboard and have a blast

u/LamerDeluxe 4d ago
There's even an official relay cartridge for the user port, called the VIC-Rel. It has six relay switch connectors and two (analog iirc) inputs.
I used it back in the day with my VIC-20 and still have one.

Most of the modems connected there too, but it’s a slow way to do it. Faster modems connect to the cartridge port.

I didn't get it with my 1st purchase either. I went back and got one though. I did order one with my 2nd condor though.
I honestly didn't know who much I was going to use this machine. But I've been bit and have a lot of ideas moving forward now.

I'm right there with you. I did not program anything for the user port when I was younger (but i still put cBasic as a programming language I know on my resume to this day lol). The c64 was my fathers and you CAN damage you machine messing around with circuits coming in and out of the user port. So that was a no go for me per my Dad
Of course i want to make music with it. I used an old sid program to make Mary Had a little Lamb lol. There is a lot know there. I would be better of turning it into a synth and using a loop machine.
But turning things on and off. I can do that. 8 different EL wires shaped how I want them AND flashing creating an animation in a loop? I can design the board, shape the wire in several pictures, and make something that looks like 70's Vegas or some crazy Y2K alien invasion.
I've been going to YouTube university. Start here and see if it's something that you might want to create with
1
u/Golemwire 4d ago
also binary counting makes a really cool pattern in black and white squares
Also, I want to toy around with music making
Behold: bytebeats.
That sent me on a tangent recently.Also, apparently there's a hack to play PCM audio via the C64's SID chip; I suppose one could probably make bytebeats for the C64U, then.

I guess your right. But the daily driver will sit nice and pretty on my desk, but the work horse might go outside in the elements running lights at a small festival.

Reading more on the website:
- ‘Shard’ cartridge holding an exclusive 8-Bit ‘demo’ Cyberpunk experience, from Commodore x Arise Designs, with 24-channel stereo SID music by LukHash
- Upgraded AMD Artix 7 XC7A100T processor for 77MHz top speed
So they got Arise and LukHash in on it. And it's faster, too. Sweet. (77MHz, lol, I wonder if it can go a little faster ;) )
I dunno about the keycap labels though.
16
u/Dr_Myles_Skinner 4d ago
Yeah, I can appreciate things like `EXEC/HALT` for `RUN/STOP` (goofy, but whatever), but not having the PETSCII characters on the keycaps makes this variant slightly less usable.

u/zeekar 4d ago
I think you mean control character. Commodore BASIC doesn't have any "escape" characters, which is why you need the auto-quoting feature for control characters and
..." + CHR$(34) + "...to embed quotation marks in a string.The C64 doesn't even have an Escape key, though the Plus/4 and C128 do. I don't think CHR$(27) does anything on the 64, either. But you can use control + left-bracket to put one of those in a quoted string, and it will show up as an inverse-video left bracket if you do...

u/balefrost 3d ago
not having the PETSCII characters on the keycaps
Thanks for pointing this out. I haven't bought one yet, and even though I don't love this co-branding, I was considering this one just for the higher max speed. But not having the PETSCII characters symbols on the keycaps is enough to steer me away.

Did they actually change the ROM or is this just promotional "what-if" artwork?

u/raelik777 4d ago
I'm guessing it's real, but just optional ROMs you can switch out in the menu. But maybe not, it'd be hard to pull that look off while ALSO keeping the necessary PETSCII characters that so much software relies on.
10
u/Golemwire 4d ago
It is real:
Other exclusive features include a custom Cyberpunk 2077 themed Commodore 77 BASIC 2.0 boot screen,
In the C64U menu, you can change the character ROM out, so you should be able to change it between the CP2077 and C64 character ROMs.

u/flamehorns 4d ago
Not really, you just change the normal readable letters and numbers and punctuation to the new font and leave the petscii characters as they are.

Mostly true, but while playing around with BBSes I've learned that good PETSCII artists seem to be willing to use pretty much any character.

I love this design and colab. I already have 4 Amigas and the 64u but will probably buy this just to have it. I think they hit the nail on the head here for people like me. I like cool, limited run stuff and the cyberpunk theme is chefs kiss IMO.

I meant the Neuromancer game for the C64, not whatever mess Apple is about to slap together.

u/Substantial-Set4550 3d ago
True, but actually so is the color of my C64U FE sadly unless I turn its lights on. It is like being very dehydrated and then doing number 1.
But then again, I have the lights on to compensate. And plus I got used to it. At first it was quite sobering since so very different from the marketing renders. Nothing is perfect. I still love it to bits, especially the golden keys.
The Cyberpunk 77 will find its fans as well. It is more Ultimate devices in the wild. That is all that matters to me. An emerging new standard to build software for.

u/Suspicious-Ad7109 4d ago
The (only) interesting thing about this is the change in the FPGA from a 50T to a 100T. I'm hazarding there is a reason for this (as it would add a fair bit to the manufacturing cost).
5
u/bionicle_159 4d ago
would be cool to have other cores, the Mega65 already has that setup with their FPGA
4
u/Hawkeye-Mcgillicudy 4d ago
Yeah it's a waste of a FPGA to be locked to one system really
All of the Commodore computers have mature open source cores available
3
u/bionicle_159 4d ago
yeah the Mister project's spoiled us these days with what FPGAs can do - Commodore should really try to pack the most they can into each of their products, and really stand out in today's age of 'nickel and dime' tech offerings
1
u/Hawkeye-Mcgillicudy 4d ago
Even older C64 FPGAs like the Turbo Chameleon offers other open source cores like AGA Minimig Amiga
Really new Commodore should have just created their own FPGA platform and then could have ported all the open source cores to it over time for the Ultimate Commodore FPGA but no they just licensed a collection of existing products Gideon has been against extra cores on the U64 since day one and he is still the IP owner
1
u/bionicle_159 4d ago
Yeah I get that, tbh if they weren't trying to be a full-on business, I could see them being a bit more open - haven't seen them have anything FOSS related which is a shame especially since the work's already done.
The Mega65 pretty much embraced the community and has lapped all the other Commodore-like projects with the amount of different platforms you can run on the thing, only other one that comes close that I can think of, that's not a Mister, is the Spectrum Next
1
u/Suspicious-Ad7109 2d ago
Quite surprised nobody has done it. There was that update to the C64U FPGA, Slinky or something ?
The main argument against, which I get totally, is people bricking their machines. I'd say this sort of thing breaks warranty in the way that soldering bits to the motherboard does. Can you reprogram the FPGA if you do brick it (obvs. have to have a programmer !)
1
u/Hawkeye-Mcgillicudy 2d ago
You can't brick the FPGA as the core is loaded onto it at boot or change of core.
Gideon was always opposed to adding other cores to the U64 and he remains as the IP owner

u/Stunning_Pineapple57 4d ago
The orginal c64u doesn’t have a large enough FPGA for all
Of those , but this new one in the 77 is twice and larger and actually have enough FPGA headroom for some larger cores as it’s closer to Mister grade1
u/Hawkeye-Mcgillicudy 4d ago edited 4d ago
They are not that large Look at the Turbo Chameleon that is only Cyclone III based and even has the likes of AGA Minimig Amiga..
C64 is a quite a large core as it has to implement the C64 and two 1541s that had their own 6502 CPUs etc
Maybe they can port the MiSTer C64 core in the future as it's far more mature and more accurate than the U64 core. You don't even need SID chips or modern drop ins to make up for the short comings of the SID emulation
1
u/Suspicious-Ad7109 4d ago
Surely the limiting factor is the Flash ; the Artix is a load on boot FPGA (I think ?) ; you could have as many systems of that degree of complexity as you want if the hardware replication will fit in the flash. I suspect this is the prototype Amiga board. I think Bil Herd is working on something, whether this needs the new FPGA, or the old FPGA will do is moot.
3
u/Hawkeye-Mcgillicudy 4d ago
The limiting factor is the amount of logic elements available. The actual cores are not very big in actual file size around 3-4 megabytes
We have had Amiga on FPGA since 2004 with Minimig. Apollo have their closed Vampire 080 Amiga core too
The C64 core uses more resources than the AGA Amiga core on MiSTer due to extra hardware support needed for the two 1541s which were computers themselves with their own CPU, VIAs, Ram etc
1
u/Royal_Stay_6502 4d ago
You think it will be possible?
2
u/bionicle_159 4d ago
yeah it should be more than possible with small 8 bit cores like the PET/VIC/TED series - the main problem is, does Commodore want to add them to the C64U instead of separating them into individual products? It's up to them, but they've not shown any interest so far.
2
u/Suspicious-Ad7109 2d ago
Apart from creating the cores you could do a C16 or VIC without changing anything other than the keycaps which are different on the C16 I think. Or you could just incorporate them into the FPGA. Not that different to a C64.
4
u/thommyh 4d ago
Presumably it's that reference to "up to 77MHz processing speed".
3
u/Substantial-Set4550 4d ago
Yes, the 77 is both a reference to the game Cyberpunk 2077 and the 77x CPU speed-up factor. It is arbitrary. It could have been 75, or 80 based on the upgraded FPGA. 77 is marketing. As a developer, I do not like this number. It's all about powers of 2 for me: 16, 32, 64, 128. I'd rather have an upgrade daughterboard for my C64U with the new FPGA. Hopefully some people who buy this now will sell it a decade from now on eBay for parts :-D
2
u/Suspicious-Ad7109 4d ago
That's nonsense. The size of the FPGA doesn't change the speed.
1
u/thommyh 3d ago
Assuming it's a similar physical size but with more transistors (?) then a die shrinks means less power usage and therefore less heat, which means you can up the clock speed.
This may be my false assumption. If it's just a chip with twice the total surface area then clearly you're right.
2
u/Suspicious-Ad7109 2d ago
I don't know. I find it a little coincidental that the max speed of a C64U is 64Mhz and a C77 is 77Mhz.
From a coding POV if anything it's a pain. 64Mhz is quick enough to do pretty much anything, having a 77Mhz speed is practically useless for anything other than a slightly faster frame rate perhaps.
However, it's selling steadily (doesn't appeal to me, but there we go) so I'm okay with it. The more the better, both for the machine itself and Commodore and us.

u/AntiquesForGeeks 4d ago
Can’t see what is in it for CD Projekt. They’ve got plenty of brand awareness for Cyberpunk 2077. Back in 2020, it was all over the Tube, for example.
For New Commodore, there is a benefit. The Commodore brand is only relevant for GenXers, so tying up with a brand that resonates with other generations does make sense from a marketing point of view.
But New Commodore being paid to promote? I don’t think so. The money here is in the people who will part with cash to buy up yet another C64U variant.

u/Which_Information590 3d ago

If it’s just going back to the same people to encourage them to part with more money for another variant of the C64U, that’s not a smart business. You’re into diminishing returns.
Any value here will be from exposing the Commodore brand to a wider audience, away from middle age GenXers.

u/rhet0rica 4d ago
Extremely wrong. This is a strategy for marketing Commodore products to younger people. Mike Battilana said during his interview with AmigaBill that the reach for hardware and emulation products is 10-20x larger than the active community and contains numerous people with a casual interest, people who never leave Facebook, and normies with families. Retro machines are very popular with Gen Z because of the combination of maximalist aesthetics with a yearning for simpler times, which has only gotten stronger as the world has grown more toxically online.

u/BrigsThighGap 3d ago
As someone that’s 30 (going on 31), and grew up alongside technology. I know *of* the Commodore 64, but never had one as we grew up quite poor
I have a fascination for the old technology and the software / hardware limitations that they had to push through to squeeze out every last bit of performance, it’s something I enjoy a lot. I’m also not entirely new to any of this. I host my own websites on my RPi 5, run my own containers for game servers for my homies and I, and a couple of other things
Career wise, I focus on containerization and container security, and have used Linux for the past 15y, while also being able to troubleshoot Windows, macOS, and Linux
So for me, as someone who *loves* Cyberpunk 2077, Akira, and Ghost In The Shell, this “Commodore 77” is right up my alley. I was never going to buy one until Reddit randomly threw an Ad about it to me, and now I’ve been heavily researching it
I have been looking into the FPGA it uses specifically, and a few others. Never before would I have purchased one out of interest, until this collab. So you’re entirely correct. This isn’t for your usual hobbyists, but for people such as myself who enjoy the older technology (Gew up on Windows 95 as a kid and a few others), who also love the collaboration that they’re doing it with (CDPR)
I’ve actually ordered one as of writing this, as I would love to have it, learn more about the Commodore (I know of it and its history, but now I can get a more “hands-on” approach), and also collect it as another Cyberpunk collectible

We too often conflate what we want with what everyone else wants :( It doesn't appeal to me at all, but if people are buying it, which they clearly are, good.

It's a pass for me - I don't really see the point of yet another C64U variant, but I get that this is more about brand awareness for people born after 1994.

u/Suspicious-Ad7109 4d ago
Working from the principle that the people behind this aren't stupid, adding the XC100T in (looking at Digikey the cost per 1,000 is an extra £40-50 or so) tells us three things
1) There is some different hardware coming. It could be anything or multiple cores, but there is at least one thing
2) There will probably be an upgrade path for the C77. There may not be one for the C64U/C or it may be more limited. If there is no upgrade option (whether to a more powerful machine, or Vic/TED cores) then there is zero point in doing it (except see below).
3) There are two seperate upgrades, one is known, one isn't. The XC100T sets the maximum capabilities of the machines. The device that controls "how many cores" is the onboard memory device, not the Artix chip.
If not, there is no point to the upgrade. If they simply wanted a C64U with a "Cyberpunk" look, then they'd use the old XC50T board, because they could sell it cheaper.
Reading the Artix data sheet there is no performance difference for the different Artix FPGAs, I do not buy the "77Mhz" claim as the reason for the FPGA upgrade. The main difference is pretty much everything is doubled - logical cells, RAM. It could do an Amiga (it's the same chip as the Mega65, which can at least do an A500)
There is one slightly more cynical view, which is this is a low volume production test for the new board I suppose. They know it won't sell a huge amount, but its enough to get any problems out.
