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 large custom [[wire-wrap]]ped [[backplane]] which bolted into the front of a 19 inch rack, such as an [[H960]]; into it plugged about 40 small M-Series [[FLIP CHIP]]s.

The backplane was wired for connection to a standard [[DEC indictor panel]], which came standard with an RP11-C, mounted in the top of the rack the RP11-C backplane was mounted in.
