This reference, together with the Omni Vision PDF I had found, confirm what the previous owner told me: the pinout in the card connector is non-standard (mixed-up). Regardless, I've identified where signals are supposed to go. It's just that I am missing one of the sync lines. The device has certainly been in use since there are signs of phosphor burn. Meanwhile I have found a better source of composite video, that is [video]cameras from 2000's, which my current TV displays properly and I'll feed it to the monitor circuits as soon as I can get it from the storage room to the lab desk. Then I will see if that is enough or I need a sync separator with LM1881. Will post updates, Paolo -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
