New project: Commodore Colt
Posted: 07 Oct 2025 03:04
As an old computer collector addict, I'm paraphrasing a message from one of my best "dealers".
"Hey bub, wanna buy a Commodore Colt? It's a Commodore PC, right. I'll even throw in an Atari ST....."
Well maybe he didn't say it that way, but that's how I heard it. Preliminary testing shows about 18 ohms between the 5v line and ground. While there is some battery damage, I've beeped out all the traces in the damaged area and they seem good (at least for now). My first guess is a tantalum that has failed open maybe? Anyone else worked on a Colt that has some ideas?
Anyway, I expect this will be a longer-term project. Looks good though and even came with the original keyboard and some documentation.
