Thanks, Simon

While this product is discontinued i can find more capable UART to microsd boards accepting higher memory card capacity and wide voltage ranges but I wonder if the cardlist program they had for reading or copying sd card content was a separate add-in and how difficult or possible it would be to writ...

I never had fx-9860 but have multiple fx-cg20 and from what i see prizm sdk is as good for them, so I enjoy programming in C and experimenting with them. In the US you get fx-cg10 instead (and they are reasonably cheap on ebay - that's probably the reason i never got fx-9860...) if you need it allow...

Found the link to that serial cable adding sd card http://www.util-pocket.com/casio/ but they no longer sell it - i wonder if it would work with prizm and non-sd version of 9860 calculator

I cannot figure out from the other posts as they were edited to show "-" so maybe pm the poster. The only time i saw something on this subject was one very long review of the calculator on amazon.co.uk i believe with instructions and web references to downloads etc - maybe this will help

I remember seeing a cable with 9v or so power connector and sd socket for adding sd on non-sd casios perhaps non-sd 9860 ones and wondered if that would work on prizm - i think the page was in french... I will post a link if i find it again. I'm not sure how if it worked over usb or 3-pin interface ...

I wonder if there is any cable etc solution to add sd to a prizm please even if it would mean creating a custom add-in to view or copy from it please?

So I'm keen to know if there is a system call or some flag or memoty file which can detect that currently running add in is the first one run on the calculator so far please. I did not find such a feature. A little byproduct of my investigations: The flag which controls the MENU-key behaviour can b...

Hi Simon, I'm trying to solve a small bug (tested on emulator only so far) which only happens when the Menu key does not start anything from when in main menu) - so basically when the calculator is restarted and no other apps were run before... So I'm keen to know if there is a system call or some f...

After releasing RESTART, the boot code is executed and checks the above keys are the keys combos checked by bootloader - that would explain why bootloader is different to allow exam mode keys combo but as bootloader is not updated with os that probably disproves my assumption... do you think bootlo...
