Wondering if acid damage can just cause oddities. Seeing some weird behavior with my ToM I'm restoring and thinking it may be acid damage. But is that more of a "work or don't work" scenario or a "weird" type?
For example, things registering on some switches causing improper behavior (game locks a ball, then ejects it, but still thinks its locked), game won't hold the trap door open (which uses the hold transistor which is CPU controlled), and some other odd stuff. I have checked (and replaced) any questionable transistors.
There was some acid damage to the battery holder, but I replaced it. I didn't think it got onto the board since the WPC-S used the off-board holder. See pictures below.
Not sure, beyond replacing the headers, where i should go with this. The lower portion of the entire board looks discolored which concerns me.
