I see there no version for the Z8000 but for the
16032. Was there
really a Z8000 version?

"Fortunately for Ward, by 1980 the community of computer researchers had grown from a
few labs to a few dozen---and for the most part, the research community was moving in one
particular direction: UNIX, the castrated Multics operating system that had been spawned
from Bell Labs. UNIX was loved because it was small and portable, which meant that it
would be easy for Ward to get the operating system running on the NuMachine. The group got
the UNIX source code from Bell Labs and ported the operating system to three different
microprocessors: the Zilog Z8000, the Intel 8086, and the Motorola 68000. Although it
would not be clear for several years, by building a single-user computer with a bitmapped
display, a network interface, and a powerful microprocessor, Ward's group had just
created one of the world's first UNIX workstations.
