I am involved as a vendor of software for the VSE market, and as a
vendor of systems programming services and also outsourcing for z/OS,
z/VM and z/VSE.
Some of our vendor products have to be coded to run on both Integrated
Servers and FSI Flex boxes because we still have customers running VSE
on those boxes. These customers purchased the one-time fee ESL licenses
and can't upgrade without significant budget issues. Yet, they keep up
to date on the maintenance of their vendor products. So, they are
pro-active and install our updates while stuck running a non-supported
VSE level.
So, the question is not just:

But, also:
"Are any of my customers still running the old hardware and still paying
maintenance fees."
If yes to either question, then the vendor has to worry about the
instructions used by the code and either not use the newer instructions
unless they multi-path the code.

Like us, Phil is a vendor. For a vendor, the relevant questions are not "do
any of these things exist somewhere and powered on?" but rather
- Are any of our customers running box X? (Should be a question that can be
answer by better means than this listserve.)
- Are there any customers (prospects if you will) running box X and
*conceivably* in the market for new mainframe software (as opposed to "we're
not spending another nickel on that thing" or hobbyists like Mr. Krukosky).
Not criticizing anyone here. (In fact I sent a detailed private note to Phil
with some of our specifics in this regard.) Just trying to shed my light on
the subject from a practical point of view.

Subject: Re: Earlier than a z9?
Yes.
I have a customer running OS/390 on an MP2000. We expect them to be off by
the end of the year. We spent many an hour trying to find a way to move them
to a current platform before they decided to put more dollars into their
off-platform conversion.
I have a customer running OS/390 on a z800.
We recently moved a customer running OS/390 2.10 to a z/10.
I had a customer decommission VM&VSE on an MP2000 less than one year ago.
I know of several VSE shops running Integrated Servers.
I know of several VSE shops running FSI Flex boxes.
