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 have a tiny 1.75" by 2.25" Logitech calculator that I got all the way back in 1981 as one of those middle school band calendar sales incentives. Its still going strong on the same battery 27 years later. :)

I did have to replace the batteries on mine once so far.
