(C) 1984 DataEast

CPU: 6502 x 2
SND: AY 3-8912
OSC: 12.000 Mhz

Other Unknown Chip: DECO SSC10 M60324 3Y4I (42 pin)

DECO PCB CODE: DE-0181-0

NOTE: There was probably a top pcb missing as there was a large
ribbon cable connector on the pcb but it wasn't connected to
anything :(

Notes about this conversion:

- Uses the original M.A.C.H. 3 / Us vs. Them hardware.
- Uses the M.A.C.H. 3 / Us vs. Them conversion ROM set.
- Uses the original Pioneer PR-8210 or PR-8210A laser disc player.
- Uses a standard Cobra Command laser disc.
- Known Issues:  Graphics are poor.

 
Modifications are also required to the game hardware 
as follows:


SOUND PCB:

Add a 220 ohm resistor across R13
Add a 330 ohm resistor across R14


Wiring Harness:

The Rocket and Guns buttons will need to be reversed.
