In fact, I am staring at a 1978-79 PDP-11 Peripherals Handbook. The controllers listed for PDP-11's are the RWM03 for 11/70's (a MASSBUS controller) and the RJM02 for smaller -11's (a UNIBUS controller). I don't know if RH11's were supported on VAX. I don't want to rain on your parade, but what are you going to do when VMS Version 5.0 comes out (very soon now) and breaks all 4.x (and lower) device drivers?
