CASIO fx-82B


Brand: CASIO
Model: fx-82B
Type: Scientific calculator
Picture: CASIO fx-82B
Batteries: AA x 2
Lifetime: Introduced: 1987
Terminated: unknown
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:

Enhanced version of the CASIO fx-82A. Added features are the display modes, percentage operation, random number generation, round-off operation, hyperbolic functions, and an "OFF"-key instead of a slider.
A reader submitted this comment on the quality difference between the CASIO fx-82B and the later series, starting with this one, the CASIO fx-82C.

I have owned two 82Bs, a C and a D (before finally getting my 100D), and one of the big big problems with the B models was that, after some time, the connecting ribbon between the battery compartment and the main "print" would become dodgy (they were held pressed together, iirc), and would sometimes lose contact when the calculator was bumped, dropped, or even squeezed in just the wrong spot. Extremely annoying, of course, losing your calculation like that. I’ve seen it happen with, in total, 5 or 6 different B’s, while all the C’s I’ve seen never did that. I always had the impression that that was the most important difference between the two.
