Hi Bill,

Thanks for the suggestion. I dismissed Ultrix without much thought
unfortunately, but I actually see some pre-built images for two RL02
drives which should get me going.

For anyone who is interested in my 2.11BSD progress: I managed to get it
to under 12MB, 8MB of which are in /usr. So, it is possible, the system
works, but I am left with no /usr/src, /usr/man, /usr/doc, /usr/dict. It
can compile stuff, it boots, but man pages are always nice to have.
