I picked up one KDJ11-AA and two DLV11J?s. The serial boards were fine.
At first I thought the KDJ11 was DOA as well but when I toggled the

Q-Bus voltages seem within specs, but more to investigate.

And alas, we don't seem to have any prints for that card (although we do have
what amounts to a tech manual, so maybe we can create a set, with a certain
amount of tracing with an ohmmeter), so at the moment, at least, fixing them
isn't so easy.
