The

restoration of 1st Edition UNIX can be found at

https://code.google.com/p/unix-jun72/
although since Google Code is going away, I hope Warren can get it moved to his own archives and/or bitsavers.

First edition is still PDP-11 Unix, I believe.

I remember Dennis Ritchie showing me the source to PDP-7 Unix in his office once. It was in a bound book of sorts; the pages were copy from a line printer. I don't know what happened to that...does anyone have a copy?
