Casio Scientific Calcs Tricks/Hacks (for fx-82MS and others)

[helder7]

In this thread are some tips to use with casio scientific calculators like fx-82MS.
They are present in many sites/videos, and I decided to collect them here .

Casio Matrix Screen

Pre-Repair your calculator by following these 6 steps:
1. Turn On
2. Press 'SHIFT' Button
3. Press 'MODE' Button
4. Press 3
5. Press = Thrice
6. Turn Off Calculator (SHIFT then AC)

To Do Matrix Hack:

1. Turn On
2. Hit 'AC' button Twice
3. Press 'Mode' Button
4. Press 3
5. Press Right on Pad once
6. Press 3
7. Press 'SHIFT'
8. Press 1
9. Press 3
9. Press 'M+' Button Repeatly (until screen changes, press 'M+' again to change to last screen possible)
10. Press 2
11. Press UP on Pad once
12. Repeatly press 3 and 0 until screen is full (Start with 3)
* When you can't type anymore press =
* When you reach 'Data Full', Hit = again
Then:
13. Press = Three Times
14. Press 0
15. Press 1
* It Should then say 'Stack ERROR' or another ERROR
16. Press UP on Pad once
17. Press LEFT on Pad Once (You should start at a % symbol most times)

For the Detail Part:

1. Press 'SHIFT' Button once
2. Pess 'DEL' Button once
3. Hold LEFT on Pad until you reach the three's and zero's you typed in previously, carfully select the square next to the last number.
4. Start press 'DEL' button repeatly, until the numbers are dissapearing on the left
5. Carfully delete the last number, then press 'DEL' once more to change into a new layout
6. Press 'SHIFT' Button once
7. Press 'DEL' Button once
8. Press 'DEL' Five times
9. Repeat the buttons: C (nCr Button) . (dot) * (*''' Button) . (dot)
aka -> C.*.
10. Do this until you see a 'h' with a line through its arm
11. Press RIGHT on Pad once
12. Hold LEFT on Pad till you reach the end
13. Press 'SHIFT' Button once
14. Press 'DEL' Button once
15. Press 8

What is it?: It is still unkown if it is a feature casio added, or just a technical flaw were the screen doesn't know what to display, because of the tampering with the calculators system. Does no harm to your calculator. To turn this off, press 'ON' Button. It is still hard to believe that such a detail has been found on a calculator, so would this be an easter egg leaked?

Casio Service Mode - (by error17)

1. Hold 'SHIFT' Button, as well as holding 7, then press 'ON' Button
2. Press 'SHIFT' Button repeatively until a 1 is the only thing displaying in the bottom right
3. Press 'ALPHA' Button
4. Press 'MODE' Button
5. Press LEFT on Pad
6. Press UP on Pad
7. Press RIGHT on Pad
8. Press all black scientific buttons on first row from left to right to display 10
9. Press DOWN on Pad
10. Press all black scientific buttons on second row from left to right to display 17
11. Press all buttons after second row from left to right in descending row order, till the last button is =

What is it?: It is a feature built, so that before packaging the calculator, an employee runs the test to make sure its working.

Hey how do you get the * in c.*.?

BTW there's a funny video: casio fx 82ms trick to convert into fx 570 ms and do complex vectors and equation calculations
If you do this you can get other functions on the fx-82MS
And the video itself is very funny somehow too
