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.

In each case, going from single core-single processor to multiprocessor and then from multiprocessor to multicore would require changes in the operating system to recognize the extra processors and then the cores.
