All, With the freeing up of the Unix source, not only can I open up the Unix Archive to anonymous downloads, but I can now make my Unix Tree web site available anonymously: http://minnie.tuhs.org/UnixTree/ Here is where you will find unpacked versions of Unix source code, and a means of comparing files between different versions. Cheers, Warren P.S Thanks to the many people who have set up mirrors of the Unix Archive.
