I don't suppose there's any part of Clearpoint left operating that I could
ask is there?

My current guess is currently leaning towards a video board of some sort.
I'm not sure if I mentioned it in the first mail, but it also has a female
9pin DIN connector, which is what Sun3s used for mono video. However, I
don't know why a video board would have a Norm/Diag switch, or a reset
