On the CPU board there is an additional 3-part connector. This is power.
It's wired as follows:
1 - +12v
2 - GND
3 - +5v
On the Video board, there is an additional 6-part connector. This is
the video connector. It's wired as follows:
1 - RED
2 - BLU
3 - GRN
4 - SYNC
5 - VIDEO GND
6 - (Not used)
Galaga also has the option of a Rapid Fire board. This is a small board
that allows the fire button to be held down and your ship to continuously
fire shots at the enemy. Holding this board with the circuits facing you
and the connectors on the bottom, the pins are numbered 1-9 (with #3 missing).
The top set of connectors (J-1) is used for rapid fire, the bottom set (J-2)
is used for single fire. It's wired as follows:
1 - (Not used)
2 - (Not used)
3 - (Not present)
4 - (Not used)
5 - FIRE BUTTON (GND)
6 - LOGIC GND
7 - FIRE (From Galaga CPU board)
8 - FIRE BUTTON
9 - +5v
There are two sets of DIP switches on the Galaga CPU board. They are labeled
6J and 6K (6K is on top).
6J is used for setting the difficulty of Galaga. Switch 7 is not used on 6J,
the rest are as follows:
Switch #1 is used for selecting the type of 1 or 2 player games:
When this switch is OFF:
1 Player Game: Press the 1 player start button.
%w, 3, 4, or 5 fighters.
2 Player Game: Press the 2 player start button.
2, 3, 4, or 5 fighters EACH.
When switch #1 is ON:
1 Player Game: Press the 1 player start button.
2, 3, 4, or 5 fighters.
1 Player Game: Press the TWO PLAYER start button
for a ONE PLAYER game with 5, 7, 9, or 11 fighters.

Galaga 3
========
There are two boards, both with blue solder masks.
The top one (slightly larger) is the CPU board, has the 4 processors
and program EPROMS, and holds a small credit-card sized daughter
board that plugs into a 28-pin DIP socket near the EPROMS. It also has
'DG-09-2' silk-screened in one corner near the main connector. The bottom
board is the video board. It has a small 5 pin connector in one corner
for the video output signal, wired as follows :
(closest to corner of board) 1 - Red
2 - Blue
3 - Green
4 - Sync
5 - Video GND
Note in my game, this connector has had wires soldered straight to it
and these brought around and soldered to the main connector in the
positions shown below, and the monitor wired to this connector instead.

Power comes in on the above connector.
There are two sets of DIP switches on the Galaga CPU board. I'll label them
SWA and SWB following the schematic. SWA is closest to the corner of the
board (located at 11C), SWB closest to the main connector (located at 11E).
Switch bank SWA sets the number of credits, lives and lives given at certain
scores.

SWB is used for setting the difficulty of Galaga. Switches SW4, SW7,
and SW8 don't appear to do anything. (This differs slightly
from switch bank 6J as specified by z_morganrw@ccsvax.sfasu.edu) :
SW1 SW2

OFF ON Rank "C"
ON OFF Rank "D" - Hardest level of play.
