Frequently Asked Casio fx Calculator Questions

What is Casio's natural display on fx-991ES and fx-82ES?

The natural textbook display is a way of displaying formulae in the closest possible way to handwriting. For example, fractions are displayed vertically.

You can enable MathO mode using SHIFT SETUP, 1.

How to reset Casio fx-991ES or fx-82ES?

  1. Turn the calculator on with the ON button. There is no hardware reset button on the back.
  2. SHIFT 9 to enter Reset. A list of items which can be reset are shown.
  3. 3 to select the Reset All option.
  4. = to confirm the reset. The calculator has been reset at this point.
  5. AC to return to normal calculation, or SHIFT AC to turn the calculator off.

    Hi, very interesting your emulator. I like to play with it a little bit. Can you be so kind and send me the download link?

    I have a question: on the German market there is a variant available, namely the Casio FX-991DE X. Do you happen to know what are the differences between that one and your emulated version? (I mean, apart from some language terms).

    Thanks in advance,

      Currently the emulator isn’t available for macOS. Do you have a virtual machine you could run it in? I’ve had success using Wine on macOS too which doesn’t require a VM.

        Hello George. Thanks for the quick reply! It works perfectly. I can defenitely use this emulator in class. Apparently, most of the students use a more recent model: the 82 Plus. The design is slightly different but I could not see any difference with repsect to the buttons of both models. However, do you, by chance, also have an emulator for the Casio fx-82 PLUS? Thanks in advance! Markus

    I have a Casio fx-20 scientific calculator dating from the mid 70s. Been well looked after. Today it stopped working (used it earlier in the day). The display is lit (a 0 lights up) -- but the keys cannot be activated. None of them works. I checked the batteries and changing them made no difference. Is there a way to open it up and maybe clean something inside? I love it and want to continue using it. Thank you.

          No, but they work great for me in macOS with Wine. I can try to create pre-wrapped Wine versions of the emulators so you don't have to install Wine yourself, if that's something you'd like?

          The zip contains three executables. The ones entitled 'Run _' are the emulators for the two models of Casio calculator that these tutorials encompass: fx-82ES and fx-991ES PLUS. The third file is a 'common' file with resources needed—you don't need to run this yourself.

            I'm sure I made a headache to you, I'm so sorry for that.

            The problem is that I didn't see any zip as an attachment

            could you attach it again please.
