So, this is a kind gesture made for the benefit of software archaeologists. Retroactively applying some kind of modern-hippie license would cost a tremendous amount of time and money.
As a matter of fact, whenever I think about the original UNIX and how far we've come from that to modern day operating systems, I get a little nostalgic, and feel like back then software development was done for much more than just money.
Also, it's pity that this work of art (and many other pieces of software alike) have always been under the ownership of some "corporate" guys.
This is roughly the same as signing a quit-claim deed. How much significance it has depends on how strong your previous ownership interest was in whatever you are saying you won't sue over. (For example, if I sign a quit-claim assertion over the Brooklyn Bridge, it doesn't mean much. :-)
But given this was sufficient so that the people who had been keeping private copies of Unix source, confident enough that they wouldn't be sued into oblivion, it's certainly significant in that sense.
I believe this would be closer to "Shared Source" than anything else.
I question how much it really matters. If you wanted to create something like xv6 (the x86 remix of sixth edition Unix), you wouldn't want to keep too much of the original code anyway, would you?
Thank you sir!!
I have a shrink-wrapped 2nd edition distribution with manuals, but no source :(
Anyone have any insight on what these actually provide, feature wise over v7?
Have often wondered about these 'mystery unices'..
Am sure I will trawl the source archives..
but pointers would be useful.
Just also found this:
I wonder which version of unix I was using. This would have been around December of '87.
I think that is exactly how BSDs got started, and later led to the famous AT&T vs BSDi lawsuit.
"[...] that it will not assert its copyright rights with respect to any non-commercial copying, distribution, performance, display or creation of derivative works of Research Unix®".

We also have a blit emulator, but it's for Plan 9 only at the moment.
It's unclear whether there exists a sun m68k emulator that could run v9.
Nokia bought Alcatel-Lucent over year ago. See for yourself: http://www.alcatel-lucent.com
The paths of mergers and acquisitions are indeed meandering.
Alcatel-Lucent makes the source code of 8th, 9th and 10th Editions of Unix public
Since the general usage of the word open source has implications about the a "free" license to use too.
*edited for clarity and a typo.
A much more detailed discussion of the origin of the term and its initial use appears here . The latter link in particular is interesting reading, because it includes the political dimensions (especiall w.r.t O'Reilly's difficulties with the FSF).
