CASIO fx-82B

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.

Dear Ernst,

I thought you might be interested in what follows – or maybe it is commonplace?

I have a Casio scientific calculator fx-82B that I bought in 1988 and – after 36 years I still haven’t replaced the original two AA batteries.

But that’s perhaps not strictly true. In 1991 I took a data analysis exam for my masters degree and was advised beforehand that I would need a scientific calculator and to ensure that there would be no problem I should put in new batteries. I did that but after the exam I put the old batteries back and haven’t removed them since.

The calculator has been on my desk for the past 36 years. I don’t use it a lot, perhaps a few times a week. And I appreciate that calculators don’t use a lot of electricity. But even so!

Best wishes,

Humphrey
