Public domain software for PC based unix, xenix etc.

[Maria Ibanez]

Hi there,

I was wondering if someone could give me pointers on the availability
of public domain sofware for PC based unix ( for 80386 processor).
I am interested in UNIX, C, C++, lisp, prolog, E.S. shells, emacs, 
etc. -- well basically the software that could be used for AI and Unix/C 
kind of stuff. Please also point to  the sources of online/printed 
documentation if you know of any.


Thanks very much,
