I remember being at small software company (mirror.tmc.com :) and we bought
a Vax750 and mtXinu came and supported 4.1c BSD on it (Ed Gould himself),
and then we got upgraded to 4.2 when it came out. I remember waiting on
tenterhooks for the upgrade. And having my mind blown when I typed in the
"network programming" exercises and found sockets a way for two unrelated
processes to communicate.
Unless my memory's wrong about the 4.1c/4.2 thing. I think we had an emacs
tape (CCA? Unipress? Not sure) that needed 4.2 and we just had to wait for
the supported version.
