Digital Equipment Corporation ( manufacturer) DEC: / dek/, n. n. Commonly used abbreviation for Digital Equipment Corporation, later deprecated by DEC itself in favor of “ Digital” and now entirely obsolete following the buyout by Compaq. Before the killer micro revolution of the late 1980s, hackerdom was closely symbiotic with DEC' s pioneering timesharing machines. The first of the group of cultures described by this lexicon nucleated around the PDP- 1 ( see TMRC). Subsequently, the PDP- 6, PDP- 10, PDP- 20, PDP- 11 and VAX were all foci of large and important hackerdoms, and DEC machines long dominated the ARPANET and Internet machine population. DEC was the technological leader of the minicomputer era ( roughly 1967 to 1987), but its failure to embrace microcomputers and Unix early cost it heavily in profits and prestige after silicon got cheap. Nevertheless, the microprocessor design tradition owes a major debt to the PDP- 11 instruction set, and every one of the major general- purpose microcomputer OSs so far ( CP/ M, MS- DOS, Unix, OS/ 2, Windows NT) was either genetically descended from a DEC OS, or incubated on DEC hardware, or both. Accordingly, DEC was for many years still regarded with a certain wry affection even among many hackers too young to have grown up on DEC machines.
