The Commodore C64C I picked up a few weeks back cleaned up nicely and needed exactly zero electronic work!

I had no Commodore-specific accessories, like keyboard springs, power supply or video lead, so I've been buying those bits piecemeal as the need arose and as my optimism increased that the machine was probably going to be fixable with my minimal electronic repair skills.

Just a few days ago, I had the board out, powered up, but with no monitor attached. Between scoping CPU and memory pins and feeling the temperature of individual chips, I could determine the machine was mostly working. The tight loop indicated by the CPU activity on the scope made me think it was probably waiting for input at the BASIC prompt.

The video cable arrived today, and allowed me to confirm that that's exactly what I was seeing!

Next I need to test the Datasette. It also cleaned up nicely and seems to be running well. Somewhere I have a packet of unopened TDK audio tapes. I need to track them down!
