As a last ditch effort, I swapped RAM chips ABCDEFGH -> EFGHABCD. Now I'm getting a black screen. Is it worth getting a new RAM card? I don't have a donor machine for swapping chips?

Reseating all the chips didn’t work, voltage seems fine. Pokey chip was half out when I went in, but from my understanding is not the issue here. Contact cleaner on the way, there is a lot of oxidation especially on the GTIA.

I have a 400 that I picked up today. It was working great for about an hour. Now if I boot basic/no cart I get a blue screen with keyboard click. The If I boot PacMan I get a black screen and if I start the game just the sprites. I opened it up and reseated the daughter cards, that didn’t work.
