Ok. I know there was never a v6.5... officially. But
there are several
references to that in different bits of the early user group news letters.
This refers to v6 plus all the patches that "leaked" out of bell Labs via
udel and Lou Katz.
My question?is,? have they survived? The story sure has, but I didn't find them
in the archive..?
I think these are the same as what went other places too.

(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}
