Recently I have bought a fake fx-82MS calculator. A body is same with the original fx-82MS, but internals is little different.
The calculator is powerred from two button cells instead of one AA in fx-82MS, internal calculations are mostly same (compare with fx-991MS) but have some differences:
- 16 internal digits vs 12
- display don't blank while thinking
- cursor disappear when holding [LEFT] or [RIGHT] keys
- can't see '-----' symbols in reset modes
May be other differences.
The debug/test mode is diferent: calculator print key codes at lest and number 0183 at right.
BTW: I saw another fakes: fx-3600PV, fx-3900PV, fx-3800P (all has internals of the Sharp EL-506)
The fakes "W" series calculators has two versions: first has functions same with fx-82TL but different names, and second has another unknown calculator inside.
You may see some pictures of fake calculators at

why would someone want to fake a calculator??? to make money? i doubt it, they would have to spend quite a bit to make each fake.

This statement made me wonder a lot, and after a little search I was able to find that debug mode you were talking about.The debug/test mode is diferent: calculator print key codes at lest and number 0183 at right.
I assume it's working with all the new generation MS series.
It worked with my fx-570MS.
Here is how: (quite similar to our big calculators
)- Hold
Shift' /> and 
7' /> - Press
![[AC/on]](/dot/public/style_emoticons/default/AC-ON.jpg)
- Keep pressing Shift' /> to view all the combinations of the calculator screen until the number '1' appears, this is the keys (buttons) test mode.
- Now press all the buttons in order from left to right, top to bottom to see if the key is working or not.
- Note: Pressing anytime exits this mode, so don't try pressing it while in the key test mode, they suppose it's working since you were able to enter this mode.
- Note 2: Maybe they should assume that the Shift' /> and 7' /> buttons are working since you were able to enter this mode too.
- Note 3: The arrow buttons are in a different order.

No, that has nothing to do with the calc being fake, I just found out about the debug mode he mentioned.
If you have only one look at the calculator in his link, it's not a CASIO original at all.

This faked fx-82MS has a hidden contact at backplate. After shorting this contact you need to press the key within two seconds while display is blank.
Then you will see all segments (display is different from the original too).
Press [any key] to clear the screen.
Press again [any key] to enter a keyboard test mode. You will see not a number order codes (1, 2, 3, etc in original Casio) but in chaos order (09..65) with some key codes misses.

Hi.
fx-570MS and fx-991MS, which one is more attractive to you ? As I know, they have all the same function, aren't they? If you have these model, please tell me which one (fx-570MS and fx-991MS) do you prefer? I intend to by one, because in national test, they don't allow using Graphing calculator.
Thanks.

fx-570MS and fx-991MS both SAME calculators. A differences is a solar power only (for the fx-991MS). I use the fx-991MS.Hi.

By the way, if you need a small calculator, the Citizen SRP-350 is better and cheaper.
