I don't know much about the 32016 apart from what I've found whilst investigating the Acorn Cambridge Workstation I got this year. The National Semiconductor 16032 was released in the late 1970s and renamed shortly afterwards to the 32016, quite possibly the first consumer chip to have a full 32 bit instruction set though it 'only' had a 16 bit external data bus. It was fast but apparently unreliable unless you got a matched set of components from NatSemi to go with it.

Whitechapel Computer Works built the semi-legendary MG-1 unix workstation round one and there my knowledge ends aside from Acorn using it to power their short-lived Cambridge Workstation, and this thing 'ere - a co-processor for the Beeb Master and possibly Beeb B. I've seen pictures of this thing badged as the 'cambridge processor' courtesy of Acorn Scientific which was the branch of Acorn producing the ACW......

Operating system wise I only know of 2, PANOS and XENIX. PANOS was used for the ACW, though other readings have hinted that people who had ACWs soon binned PANOS and used XENIX instead. One of these days I'll plug this copro into a beeb and see what happens.
