Notes:
"CT" is "Center Tap" on the power transformer.  If you jumper
the diodes to convert this board like Pac-Man or Galaxian to
JAMMA, these will become Gnd.


There should be a self-test switch near the coin door somewhere,
along with a service switch and volume control.

There should be a volume pot and a reset switch on the game PCB.
