Prizm fx-CG50 announced for spring 2017

Announcement: http://www.casio.com/news/detail/casio- ... calculator

Seems as if they are basically porting the fx-CP400 3D graphing functionality.
I did not read anything regarding touch, so this is nothing like the HP Prime.

But yeah, I wonder if it will be hackable :P

At last, the official design :

So it seems to be based on the Casio Classwiz design, which leaves me a strange impression.

First pictures of a real fx-CG50 are now online :

It's the sample available at the Casio Europe stand in Didacta-Stuttgart (Germany).

Real add-in support seems to have been kept, seeing the .g3a file sizes in the storage memory.

Please share before tomorrow the tests you'd like to be performed (provided they can be performed in public - dismantling or linking to your own calculator is probably not ok).

New fx-CG50 add-ins are now available, and can still be installed and tested on fx-CG10/20. :)

For fx-CG10/20 testers, note that :
- the new add-ins use new icons designed for a main menu with a white theme, and won't look very nice with your black theme
- Convert 1.01 is not going to work properly
- 3D Graph 1.00 is going to be slow...

Any add-ins accessing RAM directly at addresses 0x88000000..0x881FFFFF will not work correctly.
SRAM has been replaced by SDRAM which is now located at addresses 0x8C000000..0x8C7FFFFF
This makes porting OS 3.00 to fx-CG10/20 almost infeasible.

ROM capacity: 32 MB
RAM capacity: 8 MB
CPU ID: same
LCD ID: same
Frequency: 0x8F001102 (116 MHz)

I know NOTHING about super-h but would it be possible to use the MMU to create a mirror of sdram at the place where the old add ins expect SRAM?

And you could inject code into the OS 3.0 startup to do the opposite?

Very thanks for the valuable information. :thumbup:

Ptune2 may not work in CG50 without CPG control.
It seems to be necessary to revise it in Ptune3.

Is 6MB that increased managed by the OS?

Sorry for being ignorant with this type of things...
Would add-in with vram address being hardcoded as 0xA8000000 still work on fx-cg50 please?
