       | Nice - the Z280 was an amazingly capable CPU which never gained
       | much popularity.
       | 
       | There is also a Unix-like OS for Z280-based systems, Uzi280 based
       | on Uzi for the Z80 by Doug Braun.
       | 
       | Uzi280 is a 7th Edition Unix clone with multiuser and
       | multitasking functionality. It supports binaries with separate
       | I&D (instruction and data spaces, similar to larger PDP11
       | systems), code sharing, process paging, and a hard-disk cache.
       | The kernel is mostly written in c and fits into a single 64K
       | memory segment.
       | 
       | A description of Uzi280 can be found at
       | https://oldcomputers.dyndns.org/public/pub/rechner/zilog/z28...
       | 
       | However, the downloads linked there no longer work. You can find
       | a copy of Uzi280 and other software for Z280-based systems at
       | https://github.com/agn453/Z280RC and an emulator at
       | https://github.com/mtdev79/z280emu

         | Update - we used to host Z280 at the Unix-AG ftp server in
         | Siegen, which is no longer online.
         | 
         | I uploaded a copy of Uzi280 release 1.12 from a backup to
         | https://multicores.org/uzi280/

         | Alan Cox has a "Fuzix" repo, that puts together Uzix variants
         | for the Z80.
