NetBSD/vax would be a good choice, though, to implement the
VAX's system calls and execute it's binaries. Though there were more
concerted efforts to do this years ago, but I don't know what became of
them. Google shows a smattering of efforts littered with broken links. :(
There was a vax-linux port started by others, and I cared for it for a
good number of years. My life changed a lot since then, I quite failed
(and failed hard!) to bring up the needed time to care for Linux, care
for GCC and Binutils, GNU libc and all those programs silently
expecting IEEE floating point support.
I'm still here to help. :)
I expect to get at least one of my VAXen online RSN (a 4000/60, with
TURBOchannel). As in a couple of weeks' time (if only not that damn COVID
thing!). It boots our ancient VAX/Linux port with an NFS-root over a PMAD
interface. Other machines may follow.
