Defense Command Jamma Adapter

Defense Command arcade game Jamma adapter that we made years ago to test Defense Command circuit boards on our Jamma test bench.

This one does not have the second player inputs wired, but otherwise looks to be complete (we typically didn't wire them up for testing as they are only used in cocktail table mode).  We honestly don't remember how we mapped the inputs for player one as this one uses a two joystick and multiple buttons. Our guess it that up and down on the Jamm input are wired to some of the buttons used by the game.

Note that you will need a Jamma fingerboard to mate this to your Jamma harness or test rig.
