I still have a copy of the V6 kernel which I ran on the University of Kent
PDP-11/40 from about 1976. The files are dated Jan 13 1981 - but I think that
was when I made off with the copy. The earliest date in the changes file is
1977.

The system was hacked a lot - because in the days before the internet we
were pretty much on our own - and actually we passed things around in the UK -
but they didn't get much further. We picked up bits when we could and when
they passed by.

It has some interesting hardware drivers - an interface to the Cambridge
ring for example - which UKC did in a big way before ethernet happened. I
think that the tty.c driver came from Jim McKie that at Heriot Watt(?).

I include a copy of conf.h where I documented the changes.
