i have a ms pacman board. i bench tested it with ground and 5 volts to pin 17, works well. however, in the game i turned it on a wisp of smoke came off the board. the trace from Ic1 regulator to the zener burned up, the zener is shorted. after i replace the zener, i'd like to bench test it with 7 volts AC. it looks like the two 7 volts Ac leads could go to pins A and C? is that correct, and all it will need? thanks
