But I never tried to get a Unix on it. UZI or Fuzix might work?
I toyed with the idea of Minix or LSX, but it would have to be stripped back and I
didn't think that the Z-80 was up to it, even though I had the 128KB bank-switched
model. With the Hi-Tech C compiler I did get a number of simple Unix programs to run, and
even found a copy of CP/M UUCP (which was overlaid to to hell and back).
Cromemco Inc sold Cromix, a "unix like os" for their Z80 based System
Three in 1979. It had many of the unix commands but some had longer
names and no UUCP. Written from scratch AFAIK. I believe you can still
find a copy online and run it under a Z80 emulator.
