Look at attached image : Clock Test.
All optos appears to already be triggered 100% of the time.
Currently got "Ingos Clockboard" but did also test with the original board, same result...

Yes...The weird thing is: both the "10-Switch Opto PCB Assembly" and the "8-Driver PCB Assembly"
has been serviced / checked and should now be in order.
(A chip on the "8-Driver PCB" was replaced, this one: SN74ALS576BN ).

All connectors have been reseated.

Is there anything else i should investigate?
