I have an Atari Tetris board that I just blew up. I hooked it up to a Zenith monitor and when I went to hook up the ground/sync pins something fizzled. When I metered the pins after it was outputting 14VDC on one pin and almost 30VDC on another!
I only see one chip that's possibly bad, there's a small spot of what looks like epoxy on one leg coming out from under the ceramic. It could have been there before for all I know. Otherwise the board visually looks okay.
If I can get a schematic I'll start following it backward to see what goes where.
