I've been digging looking for things, and came across this unit. It
looks like a RK11-D, 4 slot hex backplane with 4 quad boards in it.
Any body know for sure? Any body need one? zip 61853, IL.
Thanks, Paul

PMDC/11 == Plessey Memories Disk Controller for PDP-11.
It's a clone of a RK11-D, you can even swap boards between a PMDC/11 and a
RK11-D (I've already successully tested a RK11 boardset in a Plessey
backplane and vv.).

That's what I thought, But I wasn't 100% certain.
Thanks for the confirmation Christian.
