How can I increase CP memory to 32MB or more?
Does someone know how can I add a memory module to CP?

I would like to open the classpad for take some photos and take the number of the IC (memory's etc...) but i dont have a digital camera (also i dont have an analog one).

We must know which IC the classpad have for the memory to know if its possible increase it.

You can open it and note IC numbers.

It's probably a bit more involved than just adding or replacing memory modules. there's the addressing capability of the CPU to be considered as well as the current Memory Map which may not have room for any other memory. The BIOS would almost certainly need replacing as well since expandability wasn't a feature of the original calc. Casio most likely hard coded certain addresses and address limits to save space in ROM and if those addresses change the BIOS won't know about it. :cry:
