I don't *think* it ever saw the light of day. As
others have mentioned,
it was planned for the ABC 2xx / Cambridge Workstation machines, but I
don't think it was anything more than vapourware.
Silly random thought. IIRC, there's an empty 40 pin DIL socket on the ACW
coprocessor board, and I think it's on the 32016 sencond processor board
too (I must come and collect that from you). Wasn't that for an MMU chip?
If so, it may have been needed for unix/xenix, but not PANOS (I've never
seen a 32016 board with it fitted).
Occasionally I see comments along the lines of most
people ditching
PANOS on the ACW in favour of Xenix - but I'm yet to find any evidence
Considering how few ACWs wer made, I find that unlikely. I've never seen
a 32016 second processor or an ACW running anything but PANOS.
