Trying to debug an Opto issue with my 5768-14075-01 pcb, I bought a Pindora replacement pcb from Marco, which says it is compatible with 5768-14075-00 but doesn't say anything about -01.

Original PCB works fine (other than my intermittent opto issue), Pindora PCB when plugged in displays Ground Short Row 1.
A number of play field switches are stuck ON when I go to the test menu with the Pindora PCB installed.

Checked connections and original PCB works. Any ideas?

That's the point of the question, Marco's site say compatible with 00 not 01. Looks like others are having issues with Pindora at the moment as well on multiple machines. Got a response from Pindora, but waiting on commentary from them.

Wondered if the 00 vs 01 was for the default setting on the Optos being NO vs NC....

Apparently it shipped with both versions...
