This thread reminded me that I own a copy of the Zilog "1983/84 Components
Data Book," which I am talking to Al Kossow about scanning. It fully
details the Z80,000 on paper but does not say anything about hardware,
everything is labeled preliminary. It is dated September 1983.

Yeah, it ran on the 16 bit one but I looked and
couldn't find if they
got Unix on the z80000 (which I suspect is what Jon meant).
I spent some time attempting to confirm whether the Z80000 (the 32-bit
flat address space development of the Z8000) ever went to silicon and
was not able to confirm it did. My suspicion remains that the Z80000
was only ever a paper specification and did not even get to a first
spin. If anyone knows and has some evidence I would be glad to update
the wikipedia page.
