I'm inclined to be interested, but correct me if I'm wrong: Is there not potential for copyright infringement if code is copied to this repository? I understand what you _intend_ to do here, and that's awesome, but I'd be careful about _how_ it's done. Cheers.

Ancient Unix were released by Caldera under a 4-clause BSD license.

See http://en.wikipedia.org/wiki/Ancient_UNIX

The source code for SysV is floating around the Internet, but adding it to this repo would amount to copyright infringement.

SysV is apparently here: https://archive.org/details/ATTUNIXSystemVRelease4Version2

Yep, but please notice that AFAIK Novell holds the copyrights to this code, and (unlike the Ancient Unixen) it has not been released under a BSD-like license.

Given the author's expertise on computing, I would be extremely surprised if there were any copyright issues prof. Spinelis overlooked.

Went there hoping to read .history files of famous unix gurus.
