Digital Equipment Corporation, also known as DEC and using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. It was a leading vendor of computer systems, including computers, software, and peripherals, and its PDP and successor VAX products were the most successful of all minicomputers in terms of sales.
From 1957 until 1992 its headquarters were located in a former wool mill in Maynard, Massachusetts, since renamed Clock Tower Place and now home to multiple companies. DEC was acquired in June 1998 by Compaq, which subsequently merged with Hewlett-Packard in May 2002. Some parts of DEC, notably the compiler business and the Hudson, Massachusetts facility, were sold to Intel.
