Digital Equipment Corporation
major worldwide manufacturer of computer equipment, DEC
Digital Equipment Corporation
Digital Equipment Corporation was a pioneering
American company in the
computer industry. It is often referred to within the computing industry as DEC. (This acronym was frequently officially used by Digital itself, but the official name was always DIGITAL.) Its
PDP and
VAX products were arguably the most popular
minicomputers for the scientific and engineering communities during the 1970s and 1980s. DEC was acquired by
Compaq in June 1998, which subsequently merged with
Hewlett-Packard in May 2002.
As of 2007 its product lines were still produced under the HP name. From 1957 until 1992 its headquarters was in an old woolen mill in
Maynard, Massachusetts.

<
company> (DEC) A computer manufacturer and software vendor.
Before the
killer micro revolution of the late 1980s, hackerdom was closely symbiotic with DEC's pioneering
time-sharing machines. The first of the group of hacker cultures 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.
The first PC from DEC was a
CP/M computer called
Rainbow, announced in 1981-82.
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. However, the
microprocessor design tradition owes a heavy debt to the
PDP-11 instruction set, and every one of the major general-purpose microcomputer
operating systems so far (CP/M,
MS-DOS,
Unix,
OS/2) were either genetically descended from a DEC OS, or incubated on DEC
hardware or both. Accordingly, DEC is still regarded with a certain wry affection even among many hackers too young to have grown up on DEC machines. The contrast with
IBM is instructive.
Quarterly sales $3923M, profits -$1746M (Aug 1994).
DEC was taken over by
Compaq Computer Corporation in 1998.
