Primos?  (Yes, it is still in use.  I know the guy with the license
to maintain it.)  OS2200?  (I just spoke with people about that and
it is nothing but 1100 Exec all growed up.  Old 1100 code still works
just fine and even all that old old documentation I kept from 30 years
ago is still valid!)  xOS?  (Well, you can run Linux on top of it.)
Ansi-M/Mumps?  (Probably twice as many users as VMS if not much more.
I don't think any one is counting but there are 10's of thousands of
users of just one major application that is written in Ansi-M).

I have had my eyes opened quite a bit in the last year since I started
looking at what was available outside of academia.

Or so academ,ia would have people believe.  Just like the mantra"COBOL
is Dead".

Lot's of systems where that is not necessarily the case.  Definitely not
the case with VMS.

I agree up to here.

I would imagine the majority were running applications that were stable
and met their corporate needs just fine as they had been running them
for decades.  The problem was the need to have additional functionality
that the hardware (primarily memory) limitations made impossible.  If
it had been possible to add that functionality I would bet most would
have stayed with the OS they were familiar with.  And, avoided the cost
of not only moving to a new platform but re-writting all their unique
application or changing their business model to match some other piece
of software's idea of how a business should be run.

Oh, I can agree with that.  As I said, "It's the applications!!"
But, by the same token, the move to a new OS was not because of
a shortcoming in the old OS.  Unisys has been very successful by
making systems that still allow old code to continue to run only
with greater resources available (I remember a particular problem
I had to solve in my Univac COBOL days that was eventually tracked
down specifically to memory availability!!  That same code would
run on OS2200 today without ever exhibiting the problem I had to
fix by modifying the supporting ECL.)  IBM has had great success
by doing the same for SYSTEM-360 programs.

Hmmm....  Not so sure about that, but even if true I would imagine it
would not be a major undertaking to make the needed modifications.  And,
there are other options.  Again, all of it depends on the model that
needs to be used.  If all the original code were to be released with a
commercial friendly license one could modify the back-end to support
the new architecture.  If you have to start from scratch then you need
to start by finding a suitable compiler (and language).  And, speaking
of language, even if the original code was released much of it is in
PDP-11 Macro and would need to be re-written using the original only
as a model.  That adds the question of what language do you write it
in?  Don't get me wrong, I like C.  I am good at C. I do not make a
lot of the mistakes that C is famous for.  But......  I would probably
not choose C as the language to use for reasons I should not have to
deliniate here!!  :-)

Eventually.  They open up a lot of possibilities.  But then, if 
you are re-writting from scratch it makes it a good time to make 
the needed changes and additions.

Do your current RSX users find it useless?  Then why are they
still there?  Same goes for all those OSes I mentioned above.
Again, as much as I like Unix (and I have been doing it since
1980) it is not the only answer to any problem.

Depending on the function, that's probably not really a problem.
It is likely that in the long run those same functions might be
wanted under RSTS and RSX as well.

OK, to be honest, it was not what you would call an RTS. :-)  I was
refering to one of my pet peeves.  The Software Tools Virtual Operating
System which was probably more of a POSIX-like API than an RTS.  But
the idea was there.  Let Unix software run on non-Unix systems.  And
the list of supported systems is mind-boggling!!
