Galaga pinout

44-pin card-edge, Bootleg Galaga board

Marked as follows
Board Label
CPU MGG-703A
VIDEO MGG-703B

This two board stack is very large, the boards are approx 10 1/2" wide x 16" long. The CPU board has 4 Z80's and 7 2732s. The sound amp is an MB3712 and is located in the top left corner if you have the board oriented with the card-edge pointing up. On the right side of the board, there is a 50 pin ribbon cable and one on the bottom in the center. The video board is almost the same size as the CPU board, just 1/4" shorter. The Video board has the normal 6 2114 rams and space for either 2 2148 RAMs, or 8 2147 RAMs.

1 Ground this pin for Cocktail mode

The most notable thing about this bootleg is that it has the same pinouts as a Midway Galaga board, but no 3-pin power connector on the CPU (But there is space for it if you wanted to populate it) and the monitor connections are on the card-edge instead of a separate 6-pin video connector on the Video board.

There are two banks of 8 switch dip-switches and they have the same settings as a normal Midway Galaga board.
