Lee from More Fun Fixing It finally scores a victory in his ongoing repair series with a successful Commodore 64 restoration. After two tricky episodes filled with setbacks, this latest session delivers a clear result. The issue? A faulty Basic ROM.
The video opens with Lee sharing some interesting hardware sent by fellow enthusiasts, including diagnostic cards and ZX-81 sound boards. These side projects hint at future content, but the main focus remains on this C64 repair. Equipped with diagnostic cartridges, an oscilloscope, and a new test setup, Lee carefully works through the system to locate the fault.
The breakthrough comes after comparing the suspect machine to a working unit. When the Basic ROM is removed, the behavior matches what Lee observes on the broken C64. That discovery points straight to the faulty chip. Replacing it restores the system, proving that the C64 Basic ROM repair was the right call.
The video highlights more than the repair itself. Viewers see early production details on the board, including a rare Petzkey-style keyboard that makes this unit special. Lee also demonstrates his process of testing voltages, clocks, and signals with his oscilloscope, showing how methodical work leads to solid results.
For retro hardware fans, this repair is satisfying to watch. It showcases both the challenge of diagnosing vintage machines and the reward when everything finally clicks. The C64 Basic ROM repair not only brings this computer back to life but also adds another valuable machine to the growing collection of restored systems.
