I'll look in my collection and see if I have an HP11C.  Offhand, I

No need to check. When that calculator got stolen, the guys running the

marketed, so I ended up with an HP 32S II, one of the few RPN machines
still in their line, IIRC.

The 11C seemed bulletproof, but this 32S is a bit flaky. Its the
calculator I keep in my workshop drawer, so it's not used very often.
But it seems that at least a third of the time I want to use it, it
refuses to turn on. I've slipped a little note in its case with notes on
the recovery procedure.

When it flakes out, I'll usually just pull out my Android phone and run
the HP 48G emulator. My main complaint about that one is that it isn't
really programmable - or at least, it doesn't retain programs when the
app is killed.

I finally remembered to look into my boxes of HP calculators.  I don't
have an HP 32SII or something comparable.  In the scientific
calculator section, I found an HP 31E and a 32E.  Both of these are
low end RPN calculators with LED displays.  The 31E had a battery leak
at some time in the past and will require that I do some battery
contact rebuilding.  I can provide a complete list of what I have in
stock.

 Not really. I learned programming by creating punched cards using an IBM
26 Printing Card Punch, editing those programs by using the card
duplicating feature of those machines. Followed by pinnig stretches of
pages printed by large chain printers like to a wall, in order to study
complaints from the Fortran IV compiler, or using a pen to mark logical
errors in the source code, for later correction work on said card punch.

MY freshman year at Northeastern was the first year they didn't use punchcards for the intro fortran class. We were 'treated' to the TA giving a punchcard demonstration at one point. I uttered a prayer of thanks to the Technology Gods.
