NonProgramable RPN Calculators  Matt  02042002 This may seam like an unusual request. I'm looking for a nonprogramable RPN calculator that uses a LCD display. As read through the list of older hp's they all seam to be either RPN and nonprogramable with a red LED display, or programable with an LCD display. In a pintch, the red LEDs would be ok, but I'd like to avoid that if I could.

Re: NonProgramable RPN Calculators  Ron Ross  02042002 All LCD RPN calculators are really programmable, no real exceptions. However, do to a small technicallity, the Hp17bii and Hp19bii are not considered programmable since they only provide a solver with no branching capability. Both are RPN and the 19bii also has trig functions. Else as you said, Hp made LED calcs that were non programmable, Hp32e, Hp31e, Hp21, Hp45, Hp35, Hp27. Most will cost what an Hp19bii will cost and be harder to find.
Have I overlooked anything?
Re: NonProgramable RPN Calculators  Ellis Easley  02042002 I hadn't thought about it, but I guess you're right. Gives more perspective to the RPN vs. algebraic situation: are RPN users smarter? more demanding? are algebraic users not to be trusted?
One possibility to meet your requirement is the 17BII. You can set it to RPN, and it is not programmable in the usual sense. It has a Solver that lets you store functions that operate like the Time Value of Money program, but unless you know some undocumented things, you can't use any form of looping. Mr. Maguire could shed some light on this.
Re: NonProgramable RPN Calculators  John Ioannidis  02052002 Also: hp01, hp10, hp22, hp37, hp46, hp70, hp80, hp81, hp91, hp92, hp9805. I doubt you want to lug around a 9805 even if you could find it, though :) Why do you care about nonprogrammability? You don't *have* to program a programmable calculator!

Re: NonProgramable RPN Calculators  Disable Programming?  Paul Brogger  02062002 I tried to disable programming on my HP32S. I filled every variable (AZ and i) with a manydigit number (including large exponent) and I added a few values to the statistical sum. This seemed to bring memory down from 390 bytes down to 126.
Still programmable, I'm afraid. (That is, unless someone else can think of even more ways to eat up the little bit of memory offered with the 32S/SII models . . . )
Re: NonProgramable RPN Calculators  Disable Programming?  Raymond Del Tondo  02072002 Hi,
you could even put some glue under the PRGM mode key;)
More seriously: I'd take a 17B or 17BII, Of course they are programmable, but in a somewhat different way... So if someone looks at a 17B at first, it obviously seems to be nonprogrammable.
