In this episode of More Fun Fixing It, I take on a Commodore 64 with a classic black screen fault and some concerning internal corrosion. After a quick physical fix for a missing keyboard spring, I dig into the diagnostics using the C64 analyzer cartridge. The repair quickly escalates as I discover a bad PLA, a faulty 6510 CPU, and multiple failing 4164 RAM chips. Watch as I work through the logic to determine if this "genuine teak" plastic-covered C64 is still a rescuable machine or destined to be a parts donor.
