I assume that the board is mis-labelled or some mistake has
been made, since I removed it from a working qbus system (an 11/73).
Is it possible to put a Unibus board in a qbus system, I know it
won't work, but will it physically fit into the backplane?
I had trouble setting the clock on this system, maybe this is
the reason.
