CASIO Scientific Calculator - Original vs Imitation

How to differentiate an Original CASIO Scientific Calculator vs Imitation

[@question4552]

Actually the easiest way for me to know if you have the original Casio Calculator is if it has the Contrast adjustment setting in the menu. Never seen a single fake casio calculator has this, loved this feature! 😉

Is this a feature of all Casio models, or just the fancier ones with more features? I have an fx-85MS from my school days-one of Casio's cheaper models, at least 10 years old. It can't manipulate algebraic expressions/equations like the "solve for x" problem shown in the video. It doesn't have any contrast setting that I know of, and I bought it from a reputable store, not some random ebay listing. (Australian school exams are strict about what kinds of calculator are allowed: no symbolic algebra, calculus, graphing, etc)

I would have thought that a fake calculator may not have all the functions or is made with cheaper materials. But the fact that it cant even give you the right answers is very strange.

[@nope.0.]

The solving function has a timeout on it. If the fake pirates the ROM but uses a cheaper CPU, it won't be able to solve in time what the real one can. Different floating point modes can also give different results, so code designed for one may fail if a subbed part defaults to another.
