I got a VERY beat up control panel of ebay because I wanted the spinner. Spinner is great but all the buttons and the spinner were connected to a small PCB on the bottom of the control panel. What is this PCB for? The words "Single Player Control Panel Interface" are printed on the PCB . I thought it might be some sort of interface for the Spinner, but when tracing the circuit paths on the PCB, I found that even the buttons input go throuth the ICs on the board. Confused. Any Ideas?
