Tims Retro Corner | I Killed My VIC-20! But Can I Fix It? @TimsRetroCorner | Uploaded May 2023 | Updated October 2024, 4 hours ago.
Thanks to PCBWay for sponsoring this video - you can get the EPROM adapter PCB used in this video, and more starting at just $5 for 10 boards, from pcbway.com
So, buoyed up from my success at getting the "untested" VIC working (see youtu.be/nTLfV4o0OdI ) Decided to fit some ZIF sockets to enable me to use this machine as a 6502/6522 chip tester.

And of course it all went horribly wrong . . .
