Digging through some boxes today I found my old graphing calculator from years ago. A Casio fx-9700GE(I also found an old fx-7700G)
I cleaned the dried gunk out the battery case(always remove the batteries before storing for years) with rubbing alchohol, and replaced the batteries, although I’m sure the watch battery back up is dead now too and I didn’t have one of those.
I’ve spent half the day playing with it and trying to remember how to do stuff. I’m such a geek
I only have to avoid looking on line and feeling inferior about how much more memory and what a better processor newer models have, and woohoo new toy.
Anybody need any 12th roots or function graphs?
