This was just information that I heard from someone at Mark Williams, who had
heard it from one of the original developers of Coherent. PC/IX was very
similar to Coherent back in 1981, they both ran on the IBM PC/8088. At this
point in time, Coherent only runs in 80286 protected mode on 286 or better
processors. In 1981, Coherent and PC/IX were based on V7 UNIX. Today,
Coherent has a lot of SYSV compatibility.

I spoke to someone who took an os course in college that used Minix on the
PC/XT. He said it took well over an hour to recompile the kernel. Times sure
have changed.
