In-Reply-To: <20150107194757.GA95@amu.edu.pl> References: <201501061341.t06Dfbsh025288@coolidge.cs.dartmouth.edu> <63B244BE-7BB0-4E7F-A589-8CD4B9FF42AF@bsdimp.com> <20150107194757.GA95@amu.edu.pl> Message-ID: My main interest is actually in pre-386 code. I'd love to see how a Unix-like system could be made to work on an 8086 or a 286. Did any of that code survive to the 4.2 era or were things 32-bit only by that point?
