Hello. Perhaps you haven't been made aware yet of these series of --IMHO-- very interesting articles about Xenix 386, entitled "Xenix 2.2.3c Restoration", by Michael Casadevall, a.k.a. NCommander at the geek site https://soylentnews.org (of which he is one of the founders): Part 1: https://soylentnews.org/article.pl?sid=17/03/03/1620222 Part 2: https://soylentnews.org/article.pl?sid=17/03/07/1632251 Part 3: https://soylentnews.org/article.pl?sid=17/03/11/2014253 I wish Bela Lubkin, ex- kernel engineer at "classic" SCO, would have joined the list to comment on those articles and pour some light into the more obscure points. I sent an email to Bela some time ago telling him about the TUHS mailing list, but I didn't hear back from him. -- Josh Good
