Vintage Commodore 64 Breadbin Computer System. Diagnostic Test Cart does show some errors. Sounds are working though. I tested loading and running GEOS software from my 1541 and it worked fine. This sale is just for the C64 Breadbin system only. I can also throw in the original PSU block, but I don't recommend using it as they were known for failing and killing the computer - its better to get a new modern C64 switching PSU.
