The RP11 disk controller for the UNIBUS is for the earlier RP multi-platter moving-head magnetic disk drives (RP02-RP03). (The later RP04 and RP06 drives are un-related - they include integral controllers, and connect to the MASSBUS.)
The only version of the RP11 is the RP11-C. Like many of the earlier large peripheral controllers for the PDP-11, the RP11-C was a group of large custom wire-wrapped backplanes which bolted into the front of a 19 inch rack, such as an H960; into it plugged about 200 small M-Series FLIP CHIPs.
The backplane was wired for connection to a standard DEC indicator panel, which came standard with an RP11-C, mounted in the top of the rack the RP11-C backplane was mounted in.
