Seeing Noel's blinkenlights project and list of panels, for interest's sake
here is a picture and
decription of the Foxboro drum indicator panel from one of the hardware manuals.

There was no trace of any panel nor drum when I recovered the Foxboro 2/10
(PDP-11/15) but I did
find the print set for the above panel (schematics only, no panel hardware
details), and a set of
RC11 modules (6 flip chips) wrapped with an error list printout. I'm not even
sure if there was a
drum fitted, as none of the notes I found for the actual installation mention
it.
There was no other drive in the rack when I got there, so I'm baffled as to
what device the cards
went to.
