@mos_8502 @dankski In this case it's System V. But there's also the 386 versions of the same as well which is a little more supported, which then turned into SCO UNIX then UnixWare.

@mos_8502 @dankski
Xenix was Microsoft's licensed version of UNIX, it originally started as a v7 derived UNIX for a few systems with SCO developing the 8086 port, and after Microsoft's basically abandoning of it by the mid 80s took over the entire thing

@ChartreuseK @dankski I think there is also Minix for that class of machine.

@mos_8502 @dankski There is yeah, though I'm not certain if Minix actually takes advantage of 286 protected mode or not. While Xenix 286 certainly does,

Both of them are equally impressive in working on a plain 8086 using just the segments for mmu (no protection but still works well with the classic unix model)
