So a month ago I picked up a galaga that had no sound except the ship explosion. I was gonna try to get the sound issue fixed, but then a week later, i picked up a second galaga that is fully working. The non-working one has been sitting since, so I'm trying to unload it now.
I figure though, since i have two of them here, are there any hints on what I could do to try and troubleshoot? I know it could be the custom chips, or the ram chips, or something else alltogether.
Anyone able to tell me what socket the chips are in? I could try swapping them between boards to see if that's the problem or not. Anything else worth trying that won't involve de-soldering and re-soldering stuff?
Part of me says leave it be and not risk damaging one or both, but the other part says, hey, if I can figure out the problem and fix it, it makes unloading it that much easier.
Thanks!
