DEC VAX-11/780 announced
Digital Equipment Corporation announced the VAX-11/780 on October 25, 1977 — a 32-bit minicomputerA smaller multi-user computer from the 1960s–80s — affordable to departments rather than whole corporations. that became the benchmarkA standardized test suite for comparing systems — ImageNet, MLPerf, and SPEC define industry scoreboards. for virtual-memory UnixAn influential multitasking OS from the 1970s — files, pipes, and C shaped Linux, macOS, and BSD. systems, with first revenue shipments in January 1978.
What it was for
VAX machines ran VMS and hosted UnixAn influential multitasking OS from the 1970s — files, pipes, and C shaped Linux, macOS, and BSD. — universities, labs, and enterprises used them for email, compilers, and time-sharingRunning multiple programs on one CPU by switching quickly between them — made interactive computing economical.. The VAX architecture's virtual memory model influenced how operating systems managed address spaces. DEC's install base was where many developers first logged into a multi-user system before PCs and the web.
Why it's here

Why it mattered
It brought affordable virtual memory and timesharingRunning multiple programs on one CPU by switching quickly between them — made interactive computing economical. to departments that outgrew PDP-11s.
What it solved
Growing software needed larger address spaces and reliable virtual memory beyond 16-bit minis.
