Title

PDP-4 Computer

Description

The PDP-4 was 18-bit machine intended to be a slower, cheaper alternative to the PDP-1; it was not considered commercially successful. All later 18-bit PDP machines (7, 9 and 15) were based on a similar, but enlarged instruction set, more powerful, but based on the same concepts as the 12-bit PDP-5/PDP-8 series. One customer the PDP-4 was Atomic Energy of Canada. The installation at Chalk River, Ontario included an early PDP-4 with a display system and a new PDP-5 as interface to the research reactor instrumentation and control.
