DEC Integrated Circuits

Digital Equipment Corporation, originally founded in 1957, was a innovative company in the American computer industry. It was generally referred to within the computing industry as DEC and later as DIGITAL. In 1998, DEC was bought by Compaq, which subsequently merged with Hewlett-Packard. DEC product lines are still produced under the HP name.
