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 - GRN 3 - BLU 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 z_morganrw@ccsvax.sfasu.edu Addendum ======== From: vecoven@montefiore.ulg.ac.be (Frederic Vecoven) Newsgroups: rec.games.video.arcade.collecting Subject: GALAGA error messagesFor information : Date: Thu, 23 Feb 1995 10:18:57 MET Here are the error messages displayed by Galaga.

I don't know how I would identify my particular boards, but I'll give as much as I can. (They were from a tabletop if that matters). 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.

Addendum ======== From: vecoven@montefiore.ulg.ac.be (Frederic Vecoven) Newsgroups: rec.games.video.arcade.collecting Subject: GALAGA error messagesFor information : Date: Thu, 23 Feb 1995 10:18:57 MET The standard Galaga pinout (for the Midway boards) contains the error messages for that boardset and which location on the board is causing the problem. Now, this information does NOT correspond with the galaga pirated (the "blue" boards). As I had to desolder all the RAMs of my board, I noted the error messages (I removed one RAM at a time, boot the game, and see the error message !) Here are the results : All RAMs are 2114. Video Board =========== 6F RAM 2L G 6H RAM 2H G 6J RAM 4L G 6K RAM 4H G 6L RAM 3L G 6M RAM 3H G Main board ========== 5D the game displays "RAM OK" but you can't exit the setup page. 5C the game displays "RAM OK", then reboot forever. ______________________________________________________________________ G A L A G A ---====נננננננננננננ====--- by: Chris Griffin We stumbled across yet another ancient bootleg of Galaga with 36 pins. We checked on the Internet and on Wiretap, and found nothing on a 36 pin version, so we sat down and decided to figure out exactly what the pinouts and dipswitch settings were. Here they are, I hope other people will find a use for these pinouts on the rare 36 pin version.

If you find the Cocktail table pin let me know. There is probably a 2P Joystick also, but in the Upright mode, you just take turns with the same joystick, so I am unsure of what it would be.
