I'm missing manual on this one Thanks
Most of the time, this is a roasted IC on the MPU. Next is the opto board. You can remove opto board connectors to see if the problem clears.

Get the manual from ipdb.org so you can identify switches and connectors. You can remove the switch row connectors from the MPU to see if the problem is on the playfield or the board (can't remember which of the three was rows... check manual). Reboot and see if error persists with connector removed - if so, it's likely the board. If not, see what switches are on row 1. Inspect them all for loose wires that may be shorting. Check the wiring between switches for shorts.
