Hello,

30 years ago today on March 21st, 1993 at around
09:45:37 UTC, NetBSD was born!

I believe this makes NetBSD the oldest,
still-maintained and actively developed, free and open
source descendant of the Berkeley Software
Distribution (BSD), a true genetic Unix (albeit not
small-caps UNIX nor UNIX(tm)).

2.11BSD is older and continuous... but admittedly much less so than NetBSD. It was released in 1991 and has had almost 500 patches, the latest in the last year. It traces back to 2.9BSD released in 1983. But it still is basically only on the pdp-11...

If you want to see what the source tree looked like
back then:

cvs -d anoncvs@anoncvs.netbsd.org:/cvsroot co -D "1993-03-21 09:45:37 GMT" src

Or browse the tree at that time:
https://www.netbsd.org/~jschauma/src-1993-03-21/

Unlike me, many on this list were around at the time
and place. Would love to hear some origin stories...
