It's not that complex of a setup, there are 3 boards. the CPU board which is a normal PC mother board. The "main board" which plugs into the CPU board through the graphics card slot; the main board has the JAMMA edge, handles all of the I/O, audio well as Graphics processing. And then the ROM board which sits on top of the main board.
I'm sure if pulled off the ROM board I can identify the Audio circuit, but really all I've wanted out of this thread is to find someone else who owns this PCB to get some basic questions answered.
