The PDP-11/34 was DEC's lower-cost replacement to the PDP-11/40 as the low-end PDP-11 system capable of running time-sharing, using virtual memory; it had the limited virtual memory capabilities of the PDP-11/40, though. It was a UNIBUS machine; as such, it was normally limited to 248KB of main memory.
The CPU came in two variants: the KD11-E, and the plug-compatible replacement KD11-EA (M8265 and M8266). The latter had provision for the FP11-A floating point unit, and the KK11-A cache (the system could use either, or both).
It could be provided with either the KY11-LA Operator's Console (a limited functionality console with only halt and boot functionality), or the KY11-LB Programmer's Console.
Apparently it was cloned in the Soviet Union as the SM 1420.
