Try minix I think http://www.minix.org Minix 1.1 in 1986 aprox ran on 8086 as well as i286, no idea now what minimum processor is. Minix Book: Title: Operating Systems Design & Implementation Author: Tanenbaum Publisher: Prentice Hall - My book is from 4.1987, maybe there's been a reprint since. When later you migrate from i286 to i386 or better, FYI an amount of Minix code has been ported to run on FreeBSD (as extras not as integrated main BSD code).

Siemens in 1985, was manufacturing licensed Unix boxes, running on an 80186 CPU, the model was called "MX". It was real Unix - I was automating source build for a 7 human language & 2 CPU architecture `make world' equivalent. The code also bore copyright of some other company (can't remember, but was once well known) which had bought rights from AT&T/Bell Labs/whoever, to resell Unix in bulk. Siemens sold it as "Sinix". Deep in the MX apparently, as the 86 has no System/User CPU status or pin for MMU etc, there was a JK bistable that was addressed via port command, (so if a user knew where to write ... !). I think Siemens were a licensed second source CPU manufacturer so could get them cheap. In 1986 Siemens made the "MX2" which was NSC 32016 based it didn't suffer the MX's 86 limitations (such as no SUID pin, & Makefiles that had to be less than 32K). 1988 I wanted to buy a Unix, found the Siemens boxes in Germany at least 30% ++ over priced, so I bought a Symmetric 375 from the USA http://bim.bsn.com/~jhs/txt/symmetric.html NSC32016 based Unix the PCB was designed by Symmetic Inc. president Bill Jollitz, who later created 386BSD, fore-runner of Free+Net+Open BSD.
