Hello, I was recently working on an Atari Superman and while doing so 4 switches stopped working. The popbumper by itself, the right most drop target, the "M" rollover and the right spinner. I don't have the schematics for it to see how they are wired but by tracing them by hand and continuity testing along the way all the wiring appears to be good. Anyone have the schematics for this game and could tell me how these switches are related? Or have any other idea I could look at.
Thanks!
