Segal's 1999 Stanford lecture notes on TQFT, where to find them?

For dead links, sometimes http://archive.org helps.

In this case they might be these:

http://web.archive.org/web/20000901075112/http://www.cgtp.duke.edu/ITP99/segal/

The page you're looking for is a mirror of http://web.math.ucsb.edu/~drm/conferences/ITP99/segal/. Unfortunately, lectures 4 and 6 are missing, as are all the diagrams in lecture 1.
