Acorn were working on a port of Xenix for the NS32016
which might have been
interesting, but unfortunately it all got canned before it was finished. :-(
(I don't think anyone else managed a port to that particular CPU - there never
were many machines which used it)
The Whitechapel MG1 must have orun some unix-like OS (although I doubt it
was Zenix), and that machine is certianly 32016-based
