I scanned the reference card I had - appears to be a RK11 compatible
disk controller (but maybe/maybe not compatible at the drive bus level?)

Can't find much about this on the 'net, other than that it was a controller
for Diablo/Pertec style drives -- no idea if it's an RK11 clone or
something else entirely. Looks to be suitable for a PDP-11/20 given the
little notch missing from the side there, and the lack of a separate power
harness for the backplane.
