1985-2008?

My first "scientific" calculator, a Radio Shack EC-4012, may have finally ceased to function. The 7 key just doesn't work. I'm going to take it home and see if I can tinker it back into shape, but 23 years is a pretty good run for what was a $20 calculator back then. I've had more expensive and fancier calculators since then, but I keep coming back to this, as it's got what I need in a calculator and not much in the way of distracting extras.

The vinyl "book cover" is also stuffed with old cheatsheets dating back to high school chemistry (not to mention the instruction book).

I'm impressed. I kept accidently throwing away my High School calculators (I'd put them on my lunch tray, then forget about them when I left the lunch room), and lost my college calculator (a HP-28C that I won in a science competition) a week before the Qualifying Exam. (BAD time to lose one's calculator, by the way. I wouldn't recommend it.)

I still have the HP-32S I bought in 1992 to replace the -28C. Guess I'm getting better about not leaving stuff around.

I got a 28S my senior year of high school, and used it pretty extensively for a few years, but then hit the courses where a calculator (even one that can integrate) isn't useful. I sold my 28S to a colleague a couple of years ago, since his own HP had died and he really prefers RPN.

Mainly I use a Calc program on my PDA or a scientific calculator I got at Dollar Tree these days, but the old Radio Shack special has been the one I keep at arm's reach at work for cases when I need to do a quick calculation.
