The Computer Company That Was Right About Everything Except the Future

DEC built serious machines for serious people — then computing stopped being serious

In January 1998, a personal computer company announced it would buy the company that had spent 40 years explaining to the world what a serious computer was supposed to be.

Compaq paid roughly $9.6 billion for Digital Equipment Corporation. It sounded like an acquisition. It was closer to a historical verdict.

DEC had built the PDP-8, the machine that helped define the minicomputer. It had built VAX, the system that made engineering computing feel inevitable. It had built VMS, one of the great operating-system cultures of the late twentieth century. It had built Alpha, a 64-bit processor so ambitious it looked less like a retreat than a final act of defiance.

And still, it lost to the world it helped create.

That is the strange thing about DEC. It was not a company that failed because it could not build computers. It failed because the meaning of "computer" changed beneath it.

DEC was right about the machine.

It was wrong about where the machine would live.
