now that I have the better picture, let me see what I
can turn up.
Got it! It's the _bottom_ indicator panel from an RP15 disk controller - from
a PDP-15. I think that's the only DEC controller I've ever seen with _two_
indictor panels on it!
And no, the one in the back is not the other RP15 indicator panel; it really
is an RP11.
