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).

Revived!

Either bouncing around in my backpack knocked something back into place, or simply popping the back off jarred things enough, but before I unscrewed the core to start messing with the keys on my old calculator I decided to try it again, and now the 7 is working. And nothing else broke in the process. So looks like there's life yet in the ol' 4012.

(Unrelated aside: comics tomorrow. UPS being shut down Thurs-Sun apparently delayed things.)
