See Archive/Applications/Spencer_Tapes/unsw3.tar.gz unsw3/usr/sys/v6unix/ directory. has annotated changes and a diff (following from my writings...) In preparation to his year sabbatical, Thompson put together a Unix system to take. ``Since it was almost a release, I made a `diff' with V6. On the way to Berkeley, I stopped by Urbana-Champaign ... I left the `diff' tape there and ... [said] I wouldn't mind it if it got around.''\cite{salus2008} At the University of Illinois at Chicago Circle, research assistant Mike O'Brien got a copy of the single-file diff (from Thompson directly). Its main purpose was to keep the Bell Labs systems from crashing. O'Brien went through it, diff by diff, and annotated it so others would have some idea of what it was what and whether they were useful.\cite{mikeobrien1} ... By the end of the summer, Haley and Joy began to explore the kernel internals. With Schriebman's observance, they installed the fixes and improvements provided on the ``fifty changes'' tape from Bell Labs. As they learned to maneuver through the kernel code, they suggested several small enhancements to streamline certain bottlenecks.\cite{mckusick85}
