Can this sad broken C64 be saved?

This Commodore 64 main board had so many things wrong with it, it was a fun challenge to get it working again. Previous owner(s) had caused damage to the board by removing chips, which adds an extra layer of difficulty to troubleshooting. It all starts with the dead test cartridge doing nothing. In this video, I show my techniques for troubleshooting and fixing all of the problems. --- Video Links Special thanks to IZ8DWF who has given me great advice on repairs:    / @iz8dwf   C64 main board schematics: http://www.zimmers.net/anonftp/pub/cb...
