While browsing UCF I came across this. Thought it might be useful for someone.




EDIT:
Hmm.... this is interesting too.... 32MB flash chip on prizm?

Also, more pics: http://community.casiocalc.org/topic/4975-casio-unveils-mind-blowing-prizm-series/#entry49766
Yes, it has already been documented that the fxCG-10/20 have a 32MB flash chip. 16 MB is the file system and the other 16MB is for the boot loader, recovery code, and OS (not all is used - future OS expansion).
A later post has clearer pictures and closeups.

Aye, I took a couple of photographs when I opened up my Prizm as well, although I can't seem to find them at the moment. I was particularly sad to notice that it didn't seem to have unpopulated SD card pads anywhere.

Did the normal 9860 have any? Because there was a version that had an SD card slot...
I recall something like that happening and it was possible to put the sd card hardware back in

The SD version was exactly the same as the non-SD version, except that the SD hardware is not included.
