Interesting.... I remember it as System Productivity Facility, to
which one could add the optional PDF (Program Development Facility)
we now recognize as ISPF option 2 (mainly). Of course it's possible
that the "F" in each case stood for "Feature" rather than "Facility",
but that was long ago and far away....
My recollection is that there was an additional step. Something like
Structured Programming Facility
System Productivity Facility
Interactive System Productivity Facility
With PDF first splitting off and then merging back somewhere along the
line.
I think you are correct. SPF was developed here in Chicago at a ladies
undergarment maker. My mind is sketchy though whether it was written by
an IBM se or it could have been a joint effort. I remember our SE
trying to sell it to us. but we were out of gas, CPU wise and we
settled for FSE. I mean we were *REALLY* out of gas on our 168MP. Our
paging rate was out of sight as well. Memory in those days (IIRC) was
$10K (US) a meg and we just couldn't afford any more.
My vague recollect is that we were maxed out of memory on the 168MP,
IIRC the max was 16 meg it should have been 32 m but there was some
issue with the MP box that didn't allow that large of memory. Its' been
30 years so my memory could be wrong.
I think we went with a 3033 about 6 months later. They sort of looked
at an AP after converting to the 3033 but we just went with another
3033
I know that IBM was sent many a stand alone dump and they always came
back with "You are out of gas and need more memory" tell us something
we didn't know.
