Picture: CASIO fx-82L
Batteries: AA x 2
Lifetime: Introduced: around 1989?

Notes: The CASIO fx-82 series started with the CASIO fx-82, an ordinary scientific calculator. But CASIO kept extending this line, turning it not into just a model number but a whole calculator series. Trying to make it the non-programmable scientific calculator for school use.

So far I’ve found mention of the following types:

Functionally identical to the CASIO fx-82D, except for the larger display, hence the L designation.

For this one I’d have to thank Erwin Muijen, he found this one on a flee market and bought it for me! Thanks, Erwin!
