post-V7 AT&T
Unices have always been unavailable, at least at any price that I can
afford on my college student budget. Solaris, however, at least
started out as an implementation of SVR4 and is freely available. How
much of System V still lurks inside Solaris 10 (the last version to
include such traditional workstation elements as CDE and DPS in the X
server) and how much has been removed in favor of a more GNU-ish
userland experience? Is Solaris a good way to get a System V
experience without breaking either the bank or copyright law, or is
this a hopeless situation?
I purchased a Solaris 8 source media kit from Sun for around $100 back
when they offered it. A lot of files still have headers saying
Proprietary Unpublished AT&T source code or some such. I don't know
how different it is from System V, because I've never been able to
procure a copy of that source. It sure looks like the Solaris 8
userland, at least, is almost pure System V.

I don't think that follows from the copyright headers. Those can't be
removed unless there is (essentially) *nothing* remaining of the
original.
Alternatively, you could say that, yes, it's a System V, but it's a
late 90s System V (and Solaris 10 is a 2005 System V). So it depends
on what you are after I guess: if you want to know what System V was
like in 1980-something then Solaris won't tell you that, any more than
OS X will tell you what 4.2 BSD was like. If you want to know what a
*modern* System V or BSD is like then, sure, look at Solaris or OS X.

Solaris is not pure System V. I started working on the internals of
System V in 1985 and I have purchased a number of Solaris boxes in the
1990's and 2000's and while Solaris is based on the System V kernel,
it doesn't feel like System V.

So far, it seems that the consensus is that Solaris isn't a good
representative of System V... With that said, the second part of my
question still remains: is there a way to pay with a classic System V
environment that is both free/cheap AND legal or am I SOL?

I'm trying to get something out of Novell on this... so far they keep
on wanting to sell me Linux they seem perplexed about their ownership
of any UNIX ip, even when I point them to their own pages proclaiming
such.......

FWIW, I did ask Novell a year or so ago about releasing OSF/1 from the SysVRx
license requirement; I sent them a reminder, together with the request that
they consider giving TUHS an SysVRx source/binary license.
So far they haven't responded. Maybe I should get onto the local branch and
ask them to take it up with headquarters ... :)

I don't think there ever was "free" unix, but there was
Unixware/OpenServer...
Sadly you've missed it by 13 years...
ftp://ftp.uni-duisburg.de/SCO/docs/Free-OpenServer.pdf
I'd say troll craigslist New York & ebay... it turns up from time to
time in the neighbourhood of $25-150 or so... I think I paid $100 for
my 7.0.1 ...
It seems that anyone who sold SYSV, except for SUN(Oracle) IBM is
basically out of the market, even if they are still in business..

I won't argue the Solaris comparison, though I'm sure people could,
but certainly Mac OS X is not a good example of modern BSD. The
kernel has very little BSD in it. Look at FreeBSD, NetBSD or OpenBSD
for that.

I was really thinking in terms of userland (I don't spend much time
poking around at kernels...). You could still argue that OS X is not
a good example of a modern BSD userland of course - I don't spend
enough time with *BSD to really know what they are like, other than
that, for the most part, everything has been replaced by GNU versions
of itself in all of these systems :-). i guess OS X is kind of like
what I would have hoped a BSD might turn into in some sense.

There's more BSD in the Mac OS X kernel than you might think, at least
judging from the stream of patches that come back into FreeBSD. They
use BSD networking, and FreeBSD's 802.11 stack, for example. Some of
the file system code is also from BSD. Darwin is a classic example of
what one can do when one doesn't care where one gets one's code from.
This has both pluses and minuses...
