I may be interested in something here.
I just bought an Arkanoid that's in a very old, trashed, gorf mini cabinet. Not sure what I'm going to do with it yet (I'm just starting my Popeye restore and won't get to this cab for a while), but the sound isn't working on it and I'd like to troubleshoot that before I make any decisions about where to go with it next. I've checked all the easy stuff (speaker, volume pot, cabling) and I believe it to be a board issue at this point.
First question: What's the difference between the green and white boards? I've got a green board in mine. Also, how come I can't find schematics for Arkanoid anywhere?
PS: That same PS is in my gorf mini.
