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/z280/uzi280/uzi280.html 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 https://github.com/agn453/Z280RC and an emulator at https://github.com/mtdev79/z280emu https://github.com/mtdev79/z280emu
