Quoted from bobukcat:Do you see any voltage at all on the pins of J9 that the cabinet switches go to?
Quoted from mg81:when I pull the CPU J9 connector off, and test the voltage on the J9-9 pin is 4.72 volts, HOWEVER, when I jumper the J9-9 pin to the J9-10 pin the voltage drops to 0.00 on both pins.
Pinwiki references a memory protect switch but it's not clear to me if this is a physical switch or a software implementation of some sort.

"Adjustments, audits and diagnostics are done using the flipper and start buttons and the menu is entered upon opening the coin door (memory protect switch activated)."
