	The '''PDP-11/34''' was [[Digital Equipment Corporation\|DEC]]'s lower-cost replacement to the [[PDP-11/40]] as the low-end [[PDP-11]] system capable of running [[time-sharing]], using [[memory management]]; it had the [[PDP-11 Memory Management\|limited memory management]] capabilities of the PDP-11/40, though. It was a [[UNIBUS]] machine; as such, it was normally limited to 248KB of [[main memory]].

			==UNIBUS termination==

			Note that neither the KD11-E nor the KD11-EA has built-in [[UNIBUS and QBUS termination\|termination and pull-ups]] (unusual for PDP-11 CPUs); this is almost certainly the reason that the manual calls for the use of either an [[M9301 ROM]] or [[M9312 ROM]] (which include bus [[termination]]) at the start of their UNIBUS, in slot 3 or 4 of the CPU's [[backplane]].
