I've been working on a lot of programs and been writing them down in excel, while spending a lot of time punching away at the calculators. Has there been an emulator developed for any of these calcs? Perhaps a spreadsheet version with all the functions and some sort of stack?
HP at one time had an emulator for the 33S, but you had to be a teacher and prove to HP that you were a teacher and that you needed the emulator before they would let you have a copy.
HP currently offers a 35S emulator, as well as many others -- but you can't get it unless you show that you are a teacher, and can provide a syllabus of your class showing that the calculator is required for it.

Thats disappointing indeed.
