I went to buy a Commodore Vic 20 also for only $20 (unknown state) and the seller offered to sell this to me for “whatever.” Currently it has a bad power supply, so I’m in the process of figuring that out.

This one is on the high voltage side it’s an NPN transistor p/n C3679. It’s showing connectivity through the collector and Emitter in both directions meaning it’s bad. I ordered several in case I pop the first one since there could be more bad components. If I can’t fix this one then I really need to get ahold of some kind of PSU that has -5v so that I can test the computer itself before I go spending $50+ on a good factory PSU.
