Digital Equipment Corporation

Digital Equipment Corporation, or DEC, was a large computer company (at one time, the second-largest in the world after IBM). They made minicomputers, their signature product (and the one that led to their success), for a period, the most popular kind of computers in the world. Their product range eventually extended from small mainframes to personal computers.

It was started in 1957, in an old wool mill in Maynard, Massachusetts. The original product line was modules, System Modules. Once those were established, they started producing computers using them.

They reached the peak of their success in the 1980s, with their VAX line. However, they were unable to successfully adapt to the rise of personal computers, which turned computers into commodities, and were bought by Compaq in 1998.
