Following my success in getting 6th Edition UNIX running on a KDF11-B, with support for the MSCP disk controller, I was looking for ways to get as new a tool chain as possible onto it, with full source code (as I'd been using the tool chain from UNSW, for which the source is missing). Well, it turns out that there's an even newer one in PWB, and there are complete source and binary PWB distributions in the TUHS archive! I now have PWB/UNIX 1.0 running, and completely rebuilt from its own sources, on one of my physical /23+ boxes (and, of course, in simh). It's connected to my main (NetBSD) system using UUCP over a serial line. Oh, and it runs the University Ingres RDBMS. :) The write-up (and download) is at https://www.hamartun.priv.no/pwb.html -tih -- Most people who graduate with CS degrees don't understand the significance of Lisp.
