Yes, I have one. AFAIK it is still operational (I haven't got it all set up since
the move), if not, it will be easy to fix.

It's 4 rows of flip-chip cards (some of which may well be specific to the
RK11-C) and an H720 PSU. Some of the backplane connectors are used
for Unibus in and out and for the drive cable (2 cables, 4 drives on each)
There are also a couple of connectors (linked with that flexible DEC 
ribbon cable to connectors on the wire-wrap side) for KM11 test
boards and 4 slots for the cables from the panel. The panel may well
have been optional, mine came without it, and there is no mention of it 
really in the printset. I have a couple of the lights panels (came with my
DX11s) and I may well move one onto the RK11-C.
