RE: Your First Handheld?
At gymnasium (until 1975) we used an Aristo slide rule and a book of mathematical tables. Only one of the math teachers was interested in electronic calculators, which we called 'zakjapanners' ('pocket japs'), and we loathed him for it.
I felt the need for a calculator when I started to do research myself in the final years of Medical School (1982) and had to do statistical calculations and tests. The first one was an HP-11C, which costed me a fortune that could only be assembled when my girlfriend lent me some money… It's still in excellent condition and on its third set of cells! In 1991 I bought an HP-48SX and was annoyed that the programs I made for the 11C had to be modified quite extensively before they ran on the 48SX due to the difference between RPN and RPL. A few years ago I acquired an HP-35 including its beautiful manual. This started a renewed interest in the whole line of HP RPN calculators. I have several of them in a showcase. Now I'm preparing an RPN Tutorial in trying to convert our twin sons (who used TI-84 Plus calculators at gymnasium) to RPN. None of the tutorials I could find online appears to teach all essential basics. Hans The Netherlands |
