I can't help but toss in two cents here...
Back many years ago when I worked up at IBM Boulder we had an edict to
install VTAM access to our VM system so all the sales people around the
country could get PROFS.
There was no GCS at the time, and the whole VS/1, VTAM, VSCS thing was a
mess, unstable, and devoured our machine...
We stumbled into a project from the Rochester MN lab called SNATAM. A
true VM-based implementation of SNA. As I recall... It ran in a
couple CMS userids and all the config files were just CMS files. It
talked to MVS by CTCs and also supported attached 3745s. It was small,
neat and efficient.
Then management found our that we were running it instead of VTAM on
"such a high visibility project" and forced us to switch to the VS/1
VTAM VSCS mess. Then eventually GCS etc. Then, when the Notes edict
killed PROFS, it killed the need for VTAM there...
The silly part was that the sales people across the country never even
knew they were using VM -- just PROFS... If they knew they used VM all
the time maybe they wouldn't have talked down about it so much...
Sigh...

We still have it here, but I suspect that it is not long lived. Some of
my worst memories involve VTAM on VM. I was the VM team leader for the
IBM Education support center in Dallas in 1985 and told my manager and
my 2nd level that we should get VM/SP R4 for the remote locations we
suppported and HPO R4 for the central site 3081's. R4 was the release
with "native" VTAM support. VTAM had been supported for a while with
VS/1 or DOS/VS hosting VTAM but someone decided that GCS was the way to
go. They took a gutted MVS/XA and quickly fitted it into VM. I don't
remember that GCS abended all the time, but CP certainly did. VM/SP R4,
with and without HPO was an absolute disaster. If we went thru a day
without a CP abend, we celebrated. R4 was probably the shortest lived
VM release ever. I think it went GA in December of 1985 and was
replaced with VM/SP 4.3 in about March. It was a great improvement.
During the fall of '85, Barton Robinson practically lived with us being
the expert from the East sent to help us.
I remember the arguments inside IBM regarding VTAM vs. TCPIP. IBM was
going to be pure VTAM. It's too bad that internal IBM was so stuck on
SNA and VTAM that there could not have been an earlier combination of
the two disciplines.
