Atari Gate Array Logic Replacement PCB

(Click to enlarge)

This PCB is designed to take the place of the Atari Gate Array custom chip, often called an AVG chip - part number 137179-001. It is used on 6 vector games: Star Wars, Space Duel, Gravitar, Black Widow, Major Havoc and Quantum. The original custom chips are now impossible to find new, and if you get hold of a used one, they are expensive, and there's no guarantee how long it will last.

Take a look at the photos below, which show where the Gate Array chip is located on a Space Duel PCB, and what the replacement looks like when installed

Here is a Space Duel PCB,

chip in place, and highlighted.
