Programmed Data Processor (
PDP) was a series of
minicomputers made and marketed by the
Digital Equipment Corporation from 1957 to 1990. The name "PDP" intentionally avoided the use of the term "computer" because, at the time of the first PDPs, computers had a reputation of being large, complicated, and expensive machines, and the
venture capitalists behind Digital (especially
Georges Doriot) would not support Digital's attempting to build a "computer"; the word "minicomputer" had not yet been coined. So instead, Digital used their existing line of logic modules to build a
Programmed Data Processor and aimed it at a market that could not afford the larger computers.
