Alcatel-Lucent finally allows distribution of previously unreleased Research UNIX versions 8, 9 and 10.
UNIX-like operating systems as we know them today descended mostly from Research UNIX version 7. Versions up to 7 have been publicly available for a while now, but later versions, up to v10, were encumbered up until recently.
These files are of historical interest and are available on the UNIX Heritage Society website.

Older versions 5, 6 and 7 can be run inside a PDP-11 emulator from simh:

but what if someone steals the code?

FUCK YES
FINALLY
I never thought I'd see the day
Still non-free, I think they're open source though
thank you based nokia

It's neither free nor open source due to the non-commercial clause. It doesn't need to be. This antique software of purely historical and educational interest.
There are also ports of v6 and v7 for x86

Perhaps a bit easier to run in VMs and you can even run them on bare metal

xv6 isn't really a port. It's a educational clone of unixv6, written in ANSI C instead of v6's proto-C.
Didn't know about the other one, though. Thanks, I'll take a look at it.
What's the point of research UNIX when they've already been supplanted by BSD and Linux?

You know it isn't actively developed, right? Read the damn thread.
As for being 'supplanted', that's not strictly a good thing. BSD, and GNU even more so, added a lot of bloat to UNIX, thus taking away a part of its excellence. Reading the source code of plain UNIX, as opposed to its clones, gives you a glimpse at the truly fantastic design described by the UNIX Philosophy.
