The boardsets , front
and backside where they are mounted. (back side having the power supply and second sound board)
In particular would be how the second (backside) sound board is connected to the power supply and to the main ROM board.
The original power supply and second (rear) sound board have both been removed and the wiring harness hacked accordingly. Right now we have just the main sound board with both the front and rear speakers tied into it. It runs great, sounds fine, but would like to get the original power supply and proper rear sound board situated. (rear sound board for the stereo effect)
When they removed the original power supply and rear sound board they removed the whole backside mounting plate and everything.
Looks like it should be almost like a Stargate setup with the power supply and sound board on it's separate mounting plate.
