I used to have the rackmount version of this system (I don't recall
the /xx number, 41 maybe?)...it was quite a machine. Next to my other
main machines of the day (MicroVAX-II and a few 386 systems, this was
like 1989) it was a VERY fast box. Lack of networking was what killed
it for me. But aside from that, it was a pleasure to use.

You're in luck. I just happen to have a copy of the '82/'83
Zilog
catalog handy. It lists the S8000/31. I expect the 32 is similar. Here are
some of the specs for the 31; 6 MHz Z8001A CPU and Z8010A MMUs as well as 6
MHz Z80B CPUs. The Z8000 is a 16 bit CPU with 16 general purpose registers
and an 8 M byte address space and can perform 8, 16 and 32 bit operations.
The operating system is Zeus, a Zilog enhanced UNIX. It includes a screen
oriented editor, a symbolic debugger and more than 180 other utilities.
Other features include a HFS, compatible file, device, and interprocess
I/O, Separate code and data address space, multiple processes per user,
user program address space of up to 8 Mb (C, Fortran 77, assembler. Zilog
offered BASIC, Cobal, C, Fortran 77, Pascal and PLZ/Sys for it. The machine
has up to 4 Mb of ECC memory (1 Mb minimum) and can support up to 24 users.
Optional 9 track 1/2" magnetic tape drive. I *think* it does include a tape
cassette drive as standard. It should have a 3600 RPM 32 Mb hard drive with
45 ms access time. The standard unit is 33" high and measures 19" wide by
24" deep and weighs ~ 250 pounds. Based on the picture, it appears to be
made up of four modules stacked on top of each other and has castors
underneath. The unit is white with a vertical black strip about 6" wide on
the left side of the front. There are expansion units that can be stacked
on top of the main unit. Th unit can run off of single phase 100, 117, 220
or 240 VAC. Maximum current at 220/240 volts is 4 Amps.

BTW what, precisely, is it - does anyone on the list know of them. In his
original message to me he said that it was big and that it had been used at
a local college to teach Unix to students.
