All, I was invited to give a talk at a symposium in Paris
on the early years of Unix. Slides and recording at:

Feel free to point out the inaccuracies :-)
For example, I thought Unix was used at some point
as the OS for some of the ESS switches in AT&T, but
now I think I was mistaken.
That's a temp URL, it will move somewhere else
eventually.
Cheers, Warren
