Nathan, this might be a naive comment, but what about DEC VMS? I understand
that a fair number of users exist still, and I think it's not from the
heritage of any of those you listed? But I assume that new versions are not
being developed, and if that is part of your considerations, that would
make sense.
This world is all new to me, I'm 24. For what my opinion is worth, I prefer
the term "midrange" as this group uses. It is searchable, not ridiculous,
and actually does describe the product line. In practice, searching for
"AS/400" returns a lot of results, although some will be hopelessly dated.
Then there was the absurd "iSeries eServer", so awkward to say and type. I
find that when I am trying to explain this market segment to people, it is
easiest to say "mainframe-like", even though I know that's a bit of a
misnomer.
It seems like a lot of devices like ATMs still run on OS/2, I know I saw
OS/2 desktop recently on an train station display in LA. This excerpt from
Wikipedia may be interesting:
"IBM <

Not to detract from the "name" discussion, but I'm reminded of a
presentation given by Frank Soltis, who points out that there used to be
dozens of "server" operating systems in existence. He asserts that only 4
exist today:
1. z/OS.
2. IBM i.
3. Windows.
4. *nix.
