My first scientific calculator, a CompuCorp 324G (which still works fine) was not an RPN device. When I bought my first RPN calculator, an HP-21, I was doing some assembly programming, and RPN seemed to fit right in with that, pushing and popping the stack, so I was pretty happy with RPN and my usual calculator today is an HP 32S II.



But I haven't abandoned slide rules. I have about 75, including an Emeloid Smith Chart slide rule which is pretty handy.



73,

I always felt a little smug using RPN on the HP’s (mine was the HP

41cv) - like I was inputting data and commands the way the processor was seeing it.

?You and me both Stan, as soon as programmable calculators came out

I got my first HP calculator, I still have the last one I bought, an

HP48, and I now have an HP41 emulator on my smart phone, one of the

best HP calculators, IMHO, except for the crummy case, which is not

a problem with an emulator ;-) The only problem is that I can't save

the programs to phone memory so I'm stuck with what is in the calculator's memory.

The HP67 calculator emulator does have a way to save & recall

programs from phone memory. A very nice touch. But, the HP67 doesn't

have alpha for prompting or for output IDing. So I have to document

that in a text file for when I forget.
