there was a vax compiler and i think a vax kenfs implementation, i don’t know if there was a vax cpu/auth kernel. quite possibly not.
currently i can only find my own post on tuhs confirming the vax was a dead end. but i am sure jmk told me he found a vax compiler binary in the labs dump. i think vaxes where becoming rather passé by the time plan9 was born. -Steve > On 28 Aug 2023, at 7:21 pm, Kurt H Maier via 9fans <9fans@9fans.net> wrote: > > On Mon, Aug 28, 2023 at 12:32:55PM +0000, G B via 9fans wrote: >> Windows and Linux began on single-core single processor machines. >> Multiprocessor had been around for some time--IBM's System 360 began using >> multi-processors in 1968--but not for x86.
