 All of them plugged into a [[wire-wrap]]ped custom 9-slot [[backplane]] dual [[system unit]]. The optional KE11-E Extended Instruction Set, KE11-F Floating Instruction Set, and KT11-D Memory Management option cards all plugged into pre-wired slots in this backplane, as did the KJ11-A Stack Limit Register and the KW11-L Line Time Clock. This left one unused slot, which was wired as a UNIBUS [[Small Peripheral Controller|SPC]] slot; that slot also contained the 'UNIBUS out'.
