1985-2008?

[dvandom]

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 want to say Casio was my preferred brand then. I probably still have some that work, but they haven't been used in 10+ years.

I still have my Casio fx-570c. I'm pretty sure I got this in 1984, but I can't find any web page to validate that memory (I don't have any memory of buying a second calculator, but...). The manual doesn't seem to have a date in it. The calculator is still on its first battery.

Huh, I just opened the wallet it's in and the wallet is going slimey. Dunno if the glue or the plastic or what. Eww....

Heh, this was surprisingly easy to Google once I decided to...

Casio fx-115v "Super-FX". I probably still have two somewhere!
