I don't think it was either. I think it was an Acorn proprietary OS called
PANOS, which looked vaguely Unix-like. IIRC, it used BCPL rather than C.
Somewhere I have all the advertising blurb (but not accessible ATM, if
it's where I think it is), and I used to have a complete set of PANOS disks
and docs, but I may have given that to someone who actually has a 32016. I
never did, though for a while I did have an Acorn Scientific, which was a
Beeb and 32016 co-pro integated in a bulky box with colour monitor and hard
drive. PANOS, by the way, was names after a certain rather good Greek
restaurant in Cambridge, which Acorn staff were later banned from -- not
because of the OS, I hasten to add, but allegedly because one night Chris
Curry took a swing at Clive Sinclair in there.
