Description
Allows you to use your Irem Uniwar S game board, in a JAMMA cabinet or a super gun device.
UniWar S was produced by Irem in 1980. It is a clearly a Galaxian inspired game. Irem attampted to improve on the original game by including different level boards and multiple enemy types, with mixed results.
While the hardware is also based on Galaxian, the Uniwar S PCB is a slim stack of 3 boards with a unique pinout. Irem apparently used this hardware for their own version of Galaxian.

Important: The adapter includes and power on circuit and a video ground jumper to deal with the video DC offset produced by this PCB. The jumper must be in GND position. If the game colors appear faint, the jumper can be set to +5V. When the jumper is in this position, the video ground in the cabinet MUST BE separated from logic ground, otherwise damage due to a short circuit may occur.
