Quoted from SilverBallKid:It is hard because my "escape" button on the coin door control switch bank is faulty so I can't get out of any test or book keeping screen once I get in.
One of the primary things to be concerned with on ANY WPC game is alkaline damage to the CPU board from leaking batteries. Problems with the control switches is one of the first symptoms you see when alkaline damage occurs as the LM339s that control these switches is directly below the batteries on the WPC89 CPU board. I would do a really good corrosion inspection of the entire area below the battery compartment.
