This is probably more window dressing than anything else, but I added heat sinks to the VIC-20’s hotter running chips. Still, 🤞🏽 it helps prolong the life of its expensive and hard to source components

I also discovered the source of the video not working when I first plugged in this (the original) main board: one of the potentiometers for adjusting the video signal is broken. If you turn the machine upside-down, it causes it to lose contact with the main board and throws everything out of wack. A shake fixes it, but I’ll have to figure out a long term fix there
