Got a customer's DE playboy with 3.8v on the 5 volts, and some interesting arcs on startup. I need to replace its power board. I don't have any spare Data East ones from that era. I've seen various places that you can stick a williams 11 power board in place of the 5000 DE one. Is it any system 11 power board? I think I have the right ones, but I want to make sure. Are any modifications needed? Or can I just pull it out of a Diner or a Cyclone, and plunk it in?
