Glad you found it.

BTW on some Bally/Williams machines (e.g. Safecracker) a bad connection at the opto board (or in the wiring to it) in the playbox will cause this error on powerup and there is utterly nothing wrong with U20, the +12V, the connector or any of the fuses. Been there chased that one.
