Digital Equipment Corporation

(company)(DEC) A computer manufacturer and software vendor.

Before the killer micro revolution of the late 1980s,hackerdom was closely symbiotic with DEC's pioneeringtime-sharing machines. The first of the group of hackercultures nucleated around the PDP-1 (see TMRC).Subsequently, the PDP-6, PDP-10, PDP-20, PDP-11 andVAX were all foci of large and important hackerdoms, and DECmachines long dominated the ARPANET and Internet machinepopulation.

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 embracemicrocomputers and Unix early cost it heavily in profitsand prestige after silicon got cheap. However, themicroprocessor design tradition owes a heavy debt to thePDP-11 instruction set, and every one of the majorgeneral-purpose microcomputer operating systems so far(CP/M, MS-DOS, Unix, OS/2) were either geneticallydescended from a DEC OS, or incubated on DEC hardware orboth. Accordingly, DEC is still regarded with a certain wryaffection even among many hackers too young to have grown upon 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.
