I picked up a Seawolf last weekend and had some time to go through it last night. To start there is a old piece of tape on the front that says "Bad Board" I have correct voltages from the power Supply, +5, +12 and -5 it takes couple minutes but the voltages are stable. The board will boot and coin up but the ships and moving mines have blocks moving with them and I have no control from the periscope, no shooting nothing. The game does play to the end so I believe the board mostly working just with the graphics issues and no input from the periscope. I did some reading and understand the L connectors can be an issue and this still has those.
From what I have read this could be a connector issue or a board issue, maybe both and I'm wondering if anyone can point me in the correct direction or what else I can test. I checked voltages on the aiming board and the firing button in the top of the cab and voltages are present.
Attached are a couple pictures,
Any help is appreciated.
