Long gone, DEC is still powering the world of computing | Ars Technica

"In 1977, DEC introduced the VAX, a new line of minicomputers that featured a 32-bit instruction set architecture and virtual memory. Its operating system, VMS, was a multi-user, multitasking OS that provided features we now take for granted, including virtual memory, file sharing, and networking. It amassed a wide variety of third-party software packages that made it the most popular system in its class."

In 1982, 6.001, MIT's first-semester computer science course, used a DECsystem 20 running TOPS-20, with Emacs for the editor. In '89 I had to adapt code from a PDP-11/55 to a PDP-11/70 on a British Airways 737 ground maintenance simulator and hope nothing clobbered the brute-force entry I stuffed in the memory map; I carried the software with me from Oklahoma to England on a 20 MB disk pack the size of a large pizza. In the early '90s, we had a machine running VAXeln (a preemptive RTOS) as host computer for a human centrifuge. The same model computer and OS was used for years to run Oklahoma's Pikepass toll tag system, something I spotted when visiting the Pikepass office at the Tulsa end of the Turner Turnpike. 1993 was probably the last time I touched anything DEC except perhaps for the occasional VT100. When I graduated, Digital Equipment Corporation was a major employer along Boston's Route 128 beltway, but they were overtaken by the PC revolution.
