The [[KDF11-U CPU]] of the [[PDP-11/24]] plugs into a specially-wired slot of the -11/24 [[backplane]]. Some of the customization relates to the semi-separate [[UNIBUS]], and [[Extended UNIBUS]] used between the [[Central Processing Unit|CPU]] and [[main memory]]; others are part of the connection between the CPU and the optional [[UNIBUS map]] board, the [[KT24 UNIBUS map option|KT24]].

The table below provides the complete, detailed pinout of the edge connector of the CPU [[printed circuit board|PCB]]. Pins are identified in the usual DEC manner: pin 'XYz' is on [[DEC edge connector contact identification|connector]] 'X'; [[DEC alphabet|contact land]] 'Y' of that connector; and 'z' identifies the side. The 'Location' gives the location of the connection in the KDF11-U engineering drawings: 'Kx' is the page number, and the second field, of the form 'Xn', are the coordinates on that page. Pins which appear on multiple pages have multiple locations.

The KDF11-U CPU of the PDP-11/24 plugs into a specially-wired slot of the -11/24 backplane. Some of the customization relates to the semi-separate UNIBUS, and Extended UNIBUS used between the CPU and main memory; others are part of the connection between the CPU and the optional UNIBUS map board, the KT24.

The table below provides the complete, detailed pinout (as far as the Field Maintenance Print Set shows) of the edge connector of the CPU PCB. Pins are identified in the usual DEC manner: pin 'XYz' is on connector 'X'; contact land 'Y' of that connector; and 'z' identifies the side. The 'Location' gives the location of the connection in the KDF11-U engineering drawings: 'Kx' is the page number, and the second field, of the form 'Xn', are the coordinates on that page. Pins which appear on multiple pages have multiple locations.

Pins with blank 'Location' fields are not connected to anything (confirmed by visual inspection of a KDF11-U PCB). 'Signals' listed for such pins are those usually seen on those pins in MUD and SPC slots (which is what the transcribed list started with); they are not of any value, in reality.
