There is (or was) a github repo that has Solaris 2.5, 2.6, 8 and 11 sources.

System III sources are out there, lots of copies, but they all appear
to come from the same root source and have just been repackaged.

Bitsavers also has sources for the IS/1 or similar to a number of different
68k machines, but it's only the kernel. It's V7 based, but with bits of
system III
and system V tossed in.

Also, it's not hard to find SystemVr1 (for VAX and PDP-11), r2, r3 (several)
and r4 online.

This is buildable, and legit with permission from DEC. At least parts of it
are buildable, I've not tried to do a full system gen from sources.

hpux has a lot of docs out there. And a lot of binaries, but little source.
one of the few I've not found sources for when I was doing research on how
sync behaved, for example.
