The ball count unit on 2001 is on the bottom board. Someone has ran a wire from the snowshoe that contacts the top rivets directly to the 5V fuse. I see the small jump wire that normally connects the centre screw to the snowshoe is not present.
I have not fired up the game yet. It was a non-working project. Would this hack to the 5V source have replaced the missing small jumper wire? Or is it indicative of something else?
