Apart from the
extremely short-lived Commodore 900, were there any other Z8000
based systems? It seems odd to me how a company which was a giant in the 8-bit
market didn't even make a dent in the 16/32-bit one.
The Z8000 included the Zilog (later Exxon Office Systems) Zeus office
automation Unix boxes...
One Circuit Cellar project was a co-processor card for the IBM PC containing
a Z8000. I toyed around a while with building an S100 bus processor card
for Z8000 (long after the both the chip and systems using the bus were no longer
in general production.) Never came to anything. I still have to processor
technical manual on my shelf. It's an interesting chip, but was a bit slower
than it needed to be.
