I had a dead CPU board and it was the IC at 7f. Replaced and the board came to life. Someone had one of the MUX chips backwards so I replaced and the games up.
The problem I'm having is when the widget board is connected, it passes the startup tests but right before the game comes up it resets. When the widget board is disconnected, it boots fine and coins up, goes into setup, etc.
I can take another CPU board and everything works fine with the same power (I am using a switcher), widget board, RAM, etc.
Obviously it is one of the chips on the CPU board, just not sure where to look. Any help is greatly appreciated.
