The user RAM resides at:
0x882D4000..0x882E3000 (fx-CG 10/20)
0x88030A30..0x8803FC00 (fx-9860G/GII)

@Simon
It would be nice to have a topic to discuss the Insight add-in.
One thing that's missing is some kind of byte or text pattern search.

At least in Eastern Germany Casio calculators are very popular.
(And yes, this kind of border still exists in most people's minds...)

Casio is even producing calculators solely targeting Germany.
One example is the new DE Plus series - a modified version of the ES Plus series.

You rarely see TI or HP calculators here in Saxony.

Doesn't seem to include one...
The last time they used a backup battery was in 2007. They even removed it from their 2005 models.

www.arizone.de - one of the remaining larger calculator and school material sellers - is out of Prizms, too. ;D

Got the first question on where to buy the fx-CG 20 in Germany: http://www.casiofans.de/viewtopic.php?f=66&t=4131
Remember, the Prizm was first available in German online stores about two weeks ago!

Casio Calculators / Re: Secret debug menu

On the fx-9860G the test menu has an option that reads "Valiable Manager".
This is Japanese programming style... ;D

If so then where did you get the service ID and time stamps from?

Press [OPTN]+[EXP]+[AC/ON] to turn on your calculator. Then press [F1] followed by [9].
- The Service menu displays the service ID
- The Version menu displays the OS version and the OS+BIOS time stamps (DateO+DateA)

I did some tests in the diagnostic menu and as it seems the debug mode does not enable the cache.
That's why it is so slow and unresponsive.

Casio Calculators / Re: Defective pixels on the TFT
« on: February 27, 2011, 09:26:15 pm »
Well, I tried locating it via BASIC and the pixel seems to be fully functional.
HOWEVER, the glitch appears to be INSIDE the glass(?!), because those TFT pixels are clearly BELOW this black blob.
Also, it depends on the angle. (I can see the "defective" pixel jump)

Update: It appears to be some kind of impurity inside the transparent plastic cover.

Nice find cfxm. How did you happen upon it?

Well, a simple guess. ;D
The [OPTN]+[EXP]+[AC/ON] key combo is known for years and the Restart button always used to be special...

Casio Calculators / Secret debug menu
« on: February 27, 2011, 04:02:14 pm »
Yesterday, I found a hidden debug menu. It was not known to Simon L., so I guess it is not known to you guys either. ;D

In order to start it, you have to do the following:
- Press the Restart button plus [OPTN]+[EXP]+[AC/ON] and hold all down
- Release the Restart button
- Wait until the screen becomes white
- Now release the remaining three keys

This will display the text "Please SD Card Insert" on the LCD - maybe a remnant from Casio Prizm development.

Pressing [MENU] (hold down for quite a while) shows the following options:

Code: [Select]
[F1]: Erase User Flash Area // Clears user flash memory (0xA0C00000..0xA2000000)
[F2]: Erase Password Area // Removes user name and organization (0xA0BE0000..0xA0C00000)
[F3]: Erase MCS Backup // Clears user RAM backup on the flash (0xA0B80000..0xA0BE0000)
[F4]: Erase Add-in Language // Removes language add-ins (0xA0B60000..0xA0B80000)
[EXIT]: Flash Program // Makes copy of the OS at 0xA1000000..0xA1B60000 (and may corrupt the file system!)
Note, if you press [OPTN]+[EXP]+[AC/ON] too short, it will display the OS Error screen (which is the OS update routine started from within the BIOS). Also, if you press [OPTN]+[EXP]+[AC/ON] without the Restart button involved, it will enter the diagnostics menu. In this case you have to additionally press [F1] followed by [9].


And here is the test menu: Syscall 0x0EA7 :D

I have attached a program at the bottom.


Diagnostics, test and debug menu.

On the fx-9860G the first four bytes are significant only.

Would the 7th character on the serial # tell what the pre-installed boot code is?
The boot code version (date) is stored at 0x8000FFB0 (again, on an fx-9860G).
