What Happened to Digital Equipment Corporation?
The minicomputer giant that built the PDP and VAX — bought by Compaq in 1998 and folded away.
Digital Equipment Corporation was one of the most important computer companies ever, known for the PDP and VAX minicomputers. It declined in the 1990s and was acquired by Compaq in 1998, ending it as an independent company.
A giant of the minicomputer era
Digital Equipment Corporation was founded in 1957 in Maynard, Massachusetts. It rose to prominence on the back of the PDP series and, above all, the VAX — minicomputers that put real computing power in the hands of universities, laboratories and businesses that could never have afforded a mainframe. For decades, DEC was the name in practical computing.
The second-largest computer company
Through the 1970s and 1980s DEC grew into one of the largest computer companies on earth, in many respects second only to IBM. Its products and its culture — informal, engineering-driven, fiercely loyal — helped define the modern tech industry, and it produced a remarkable number of the industry's future founders.
Missing the PC revolution
DEC's decline lay in what it didn't do. It was slow to embrace the personal computer and open industry-standard systems, and its powerful minicomputers were undercut first by PCs and then by networked Unix servers. By the early 1990s the company was in trouble, a shadow of its former self.
Where Digital Equipment Corporation is now
In 1998, Compaq announced it would acquire Digital for roughly $9.6 billion. Two years later Compaq itself was absorbed by HP, and the Digital Equipment name faded from the industry. Today DEC survives only as a memory and as an object of study — one of the greatest computer companies ever built, gone before the century was out.
