-The '''PDP-8/A''' was [[Digital Equipment Corporation|DEC]]'s last non-[[microprocessor]] [[PDP-8 family|PDP-8]]. The KK8-A [[Central Processing Unit|CPU]] was a single [[DEC card form factor|hex]] board, which plugged into an [[OMNIBUS]] [[backplane]]. It supported both [[core memory|core]] [[main memory]] (MM8-AA and MM8-AB) and [[semiconductor]] (MS8-A).
