Easy Repair of a Commodore VIC-20 and a C64 for a friend

October 10th, 2013 Leave a comment Go to comments

I have received these computers to be repaired for a friend.

Defects found on the Commodore VIC-20:

  • Error message (device not present) when trying to access the IEC devices, like a Floppy Drive.

Defects found on the Commodore 64:

  • Black screen of death after installing the missing roms.

The repair of the Commodore VIC-20 was made by replacing a HEX Inverter Buffer 7406.

The repair of the Commodore C64 was made by replacing the MOS 906114-01 (PLA – Programmable Logic Array).
