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.
