If so then send the board in if you get it. I didn't see it listed on MAME. Unless it in a clone area. Looking at the main set only. Might not be dump. Might be version v3.0.
By the way. Leave the cabinet alone. Don't replace any of that buttons and track ball. Loses it volume if you replace those. Only if you find something is wrong then replace it. Just don't throw the old parts away. Some of those are easy fix.
