I recently purchased 155 Commodore VIC-20 motherboards from a place called “Fair Radio Sales.” And while they were selling the boards at a reasonable cost, (around $3 plus shipping) they weren’t really selling many. The problem was, they weren’t guaranteed to work. So, I decided to buy them all and get as many of them working as I could. Just by swapping chips around I managed to get around 80 of them working, and I could probably repair another 20-30 of them that have easy-to-fix problems if needed but they require soldering work, which I don’t have time for at the moment.
I felt I could sell the boards for $20 a piece plus shipping, now that they are working and since I’m already known in the community for selling Commodore stuff (where a Radio store was not). So these are now available in the store, along with spare chips if you have a board you need to repair.
I also made another purchase at the same time. One that was probably a mistake. I also bought 55 Commodore-16 keyboards. These are brand new, old-stock. It sounded like a good idea because I was told these could be converted to work with the VIC-20 and C64 by simply changing some wires around. Well, I looked up the matrix diagrams for both keyboards and checked to see how they were wired. They are indeed very similar. However, when I made the requried changes, everything wasn’t as rosy as I had hoped.
You see, there are fundamental differences between the keyboards, such as the fact that the C64 has 2 cursor keys and the C16 has 4. But, physically the keys are the same on the boards. There’s the same number in the same arrangement. They just don’t all have the same labels. So I figured, worst case, you’d simply have to “touch type” without paying attention to what the keys are labeled. However, that turned out to not be the case either.
So, the bottom line is that the keyboards do work. But the cursor keys are not only labeled wrong, but they are in the wrong physical place on the keyboard too. Also there is no restore key. And a few other keys aren’t right such as the Pi and up-arrow keys and the @ symbol. But otherwise, everything else works.
So you can use one of these keyboards on a VIC-20 or C64 for loading games from disk, etc. But it isn’t 100% compatible. On the bright side, it shares the same plungers with the 1st gen VIC/C64 keyboards, as well as the frame housing. And the keys themselves can be fitted onto a C64 keyboard. Anyway, not sure if anyone will find any use for these, but I’m selling them for $10.

If I need some VIC-20 stuff I’ll give you a holler! That’s a ton of boards!
Are the C16 keyboards still 100% compatible with your C16 motherboards?
Would you be willing to do an upgrade to 64k on a C16 motherboard for an extra fee?
I don’t have any C16 motherboards. I only have VIC-20 motherboards. And they are not 100% compatible.
In your video you said something about non-working VIC boards? Are the on/off switches the same as a 64c’s? If so I would love to buy a couple. Mine broke and trying to find new ones or at least ones that work.
would you be interested in borrowing my pet key Vic 20 for a documentary it is a all original pet style vic 20
The Commodore 16 keyboards will work with the Keyrah v2 device. The Keyrah converts a Commodore keyboard so it can be used as a USB keyboard. In my case I’ll be using the C16 keyboard with a Raspberry Pi. At $10 the price is nice for a project like this.
So, I’m new to this. I’ve seen most of your content and I think I have the hang of it. So I’ll contact you if I can.
I see that a week in, Dave has done the smart thing with the Keyboards and doubled the price! 😉
Actually, I didn’t… it’s the same price they always were.
I am typing this comment using the C16 keyboard that Dave just sent me 🙂
I have converted it to USB so I can finally type on my PC using a *real* keyboard for once.
I am just in the process of blogging how I did it…
Oh, and thanks to the magic of xmodmap I now even have the keyboard mapped almost properly. A few things are not quite right, but it’s close.
I even have the ♥graphics♥ keystrokes mapped to the closes unicode equivalents… ├───┼───┤ ╰╯ ●○ ▇▆▅▄▃▂▁ etc 🙂 Just such a shame xmodmap won’t do strings, otherwise the number keys could give me ANSI colour control sequences…
The worst thing though is a lack of a TAB key. You don’t realise how much you use it until it’s gone.
I am in dire need of a Vic-20 motherboard, do you have any left? I have an empty shell and keyboard. I have another one too that does not work. Will have to see if I can get it working.
I found a github repo for a 6502 port of GCC. I’m wondering how hard it would be to create some form of debugging interface to a VIC20 board to allow programming of it using the Arduino API (or some cut-down variant of it if g++ doesn’t want to compile – it’s still cloning at the moment… massive…).
I guess replacing the ROM chip with a flash chip wouldn’t be too hard. I’d just need to create an interface to the cartridge slot to allow direct access to the flash chip for reprogramming. And then, of course, include core components of the existing ROM within the API to keep things like the VIC chip running, which should be fun to do…
Would there be any interest in such a frankensteinian beast, or is this just one of my stupid late night ideas again?
My grandpa had a original nes but threw it out when he got the new nes classic i was sad when i herd he threw it out
Dear 8-Bit Guy:
Can you send me a C16 keyboard when you have another free new-old stock one?
Sincerely,
James Novak.
P.S. Thanks for the rare card and the signed copy of Planet X2!
It always amazes me that there are still New Old Stock out there 🙂
I would love to know how much a Commodore 64 would be
First of all I love your YouTube channel. If you come up with another working Mos 6560 chip I’d definitely buy it. Just bought a VIC off eBay and the video shows good text but blank vertical rectangular bars when using game carts. Thanks.
Do you expect to be able to offer any of these VIC motherboards for sale again? Mine is dead and I’d like to revive it.
I’m late to this party, but if you still have any working Vic-20 motherboards I’d be interested in buying one.
would you be interested in borrowing my pet key Vic 20 for a documentary it is a all original pet style vic 20 .
Hi David my name is Simon Smith and I am a fully qualified electronics engineer I might be able to help you with a video chip from the VIC 20 I just need a little bit more information about the I see that you require
Hello David my name is Sinura Siriwardhana and I need one of your VIC 20 motherboards to fix by myself and my father has put a comment in your new video telling me that my son needs one of your VIC 20 motherboards to repair can you send one, please.
Somehow I came across your YouTube channel and got hooked. It’s brought out my suppressed nerd self. I’m born in 1971, so it’s all relevant. Awesome channel. Thanks. Hopefully you feature the TI994/a one day which dad and I shared a lot of time on. They were unusual in Australia. He should have got the C64.
Fair Radio is not a ‘radio store’. It is an old school electronic surplus store that started with WII military surplus electronics, then later industrial surplus. I visited the store many times, when it was in the old railroad terminal building. They had a lot of stuff that wasn’t in their catalog or advertised online. They also sold non working test equipment by the pound, and they had a room full of it. I first visited it about 50 years ago. My pair of Lyon bench stools came from there in 1975. 🙂
Hi David, a shout out from New Zealand. I’ve been watching your channel for some years now, fantastic. I too am a Commodore “fanboy” and happen to have 2 VIC-20 breadbins, both of which have dead VIC (Video) chips. I remember as a youngster in South Africa going to the former Commodore dealership and asking for these chips in the early 90’s, but sadly by then they were already obsolete and impossible to get.
If possible I would like to purchase a couple of these IC’s off you, or if you prefer, even purchase a complete VIC-20 main board, and a spare or two of the VIC chips. I wish somebody would finally reproduce these chips (there are a couple of guys now fabricating their own IC’s in their sheds!). Anyway, I digress, but yes, please do let me know if you have some to spare still, thank you. I’m not sure what shipping would cost. No great rush, so it doesn’t need to be “overnight with DHL”, but simply a tracked parcel to New Zealand. Sorry, I realize this is likely more trouble than it’s worth for you, but off the top of your head, you may already know what the cost is, or the best option. I do often order components from the likes of Digikey and Mouser in the USA, and the shipping is not prohibitive. Don’t skimp on the cost though, I’m happy to pay a little more as a way of thanking you for years of entertainment and fond memory recollections.
Thanks again for a great show!
