I need to test a supergun I have with a fully working jamma board. The only jamma board I have results in a nonworking player 2 right move and I am trying to determine if it is the board or the supergun prior to selling it. I am pretty sure that it is a board problem but would like to verify it with a known working jamma board. I would be happy to trade beer, $$ or some arcade part(s) for testing with your board. I can stop by your place or you can bring the board to my house. Let me know if you are in the area and can help. Thanks
