The PDP-11/45 was a fast UNIBUS PDP-11 system based on the KB11-A CPU. The PDP-11/50 and PDP-11/55 used the same processor, but featuring a MS11 MOS or bipolar MOS memory, respectively.

Optionally, the machine could be configured with an FP11 floating-point processor, and a KT11-C memory management unit.

The machine had an 18-bit UNIBUS, allowing it to address 256KiW of memory.
