Notes:
              *: unpopulated 32 pin sockets
         PST532: IC for system reset and battery backup switching
        DIPSW's: Each have 10 switches.
      VOL1/VOL2: Separate volume levels for sound and voice
        CN3/CN4: Connectors for player 3 & 4 controls
        TC55257: 32K x8 SRAM
         LC3664: 8K x8 SRAM
        M548262: 256K x8 fastpage VRAM
          28WAY: Edge connector is JAMMA backwards (GND is pin 28,27; +5V is pins 26,25 etc)
                 and with RBG locations moved (i.e. not standard JAMMA)
