This is a simple board meant to work as an adapter for hooking an aimtrak up inside a Namco arcade gun (so it can be used with a PC with functional recoil). The board fits into the handle of the gun and contains through-holes for each connection between the aimtrak, connections in, and the solenoid in the gun. The board also includes a diode for the solenoid along with a TIP102 + Resistor for triggering the solenoid. Not much else to say, the board could use a lot of improvements but it gets the job done.
