Top of the line Casio Scientific

[Matt Agajanian]

Hi all.

A fee years ago, I bought an fx-991ES. Now, it’s time to add another calculator to my collection. I’m thinking the 991EX is the top model.

So, what is Casio’s top-of-the-line non-graphing scientific model?

Thanks

For the U.S. market I think the fx-991EX Classwiz is Casio's top non-graphing scientific model and a nice upgrade to the fx-115ES Plus. It has a higher resolution screen, more functions, a little more memory, is faster and looks like the more recent Casio's in styling. It also has a spreadsheet app and can output a QR code in the display for viewing graphs and other information using your smartphone. I think it is a real bargain for around $20 USD.

Currently hard to decide, because the new fx-880BTG. Check the topic here: https://www.hpmuseum.org/forum/thread-18932.html

BTW the CASIO fx-991CEX is an EX added a periodic table and few more functions but no English or you can choose japanese version (JP-900) with English language available or if you do not need periodic table, the German 991DEX is a good solution, without English but lots of additional features packed.

Dig CASIO support page and use classpad.net for all emulators free.

All of these have more functionality than a "normal" 991EX.

FYI the fx-92+ Spéciale Collége is a French version and programmable (the only programmable Classwiz).

The top-of-the-line non-graphing model would be the fx-5800P, but if you're looking for something you can walk into a store and buy in North America, then the fx-991EX is the current flagship. It has a spreadsheet, but don't get your hopes up too much - it's extremely basic.

... or fx-FD10PRO. Both (5800P and this one) is scientific and programmable (I don't know, as I can remember the two model is almost same), but I guess Matt want something looks like a scientific calculator.

BTW I do not really liked the Classwiz models initially, later I dig into the deep, and I made lots of videos about them
