I had several Nabu 1200's, a Canadian built machine which was also an 8086 with 512K
of RAM - 4 serial ports. Also ran Microsoft XENIX. Actually, you could run CP/M 86,
QNX (a Canadian nix-alike) or Xenix - Xenix was the only one of the three which
required an optional external (to the CPU) memory management unit board.

I still have 1/2 of a Nabu - the machine consisted of two parts, a DISK unit which
held the hard drive, WD controller and an 80-track floppy drive, and the CPU unit
which sat on top. I got one of my CPU units back, however the disk unit is remaining
elusive. If you are interested, you can view the CPU unit (inside and out) at my web
page (see sig).
