So it's much like a Prizm, but with a monochrome screen and a SDHC card reader? Sounds nice.

Remember the day the walrus started to fly...

I finally cleared my sig after 4 years you're happy now?

Seems that way. The 9860 GII series also has a lower resolution though. 128x64, which is incidentally the same as the old TI-86. =)

And only 1.5 MB of storage memory for add-ins.

If recompiled older add-ins should be able to work. There's nothing wrong with directly accessing the hardware as long as you do it in a safe and efficient way. My preferred method is to use a set of standardized libraries that can updated when hardware changes without having to modify someone's legacy code. For example a set_cpu_frequency(int) function could be designed to be both hardware compatible with all current casio calcs and be flexible enough to be expanded for future designs. This is also why I'm such a strong advocate for open-source projects as old apps that are no longer maintained by their original authors can no longer work if they were closed source. This is especially distressing if only a few minor modifications were required to upgrade to the  newer gII. To prevent this in the future I've been working on standardizing methods for the Prizm as it will be necessary if casio changes the hardware. In fact I'm going to try and extend these hardware libraries to all casio calcs that way standardized hardware functions can be used for  nearly half a dozen calcs. Do note that the professional software industry deals with these issues to a far more difficult level than we do. As an example look at the x86 architecture. The number of modifications and additions it has gone through is far more than the super h. And yet something like windows has to directly access the hardware on the tens of thousands of different pc's out there and is expected to work right out of the box.

List of stuff I need to do before September:
1. Finish the Emulator of the Casio Prizm (in active development)
2. Finish the the SH3 asm IDE/assembler/linker program (in active development)
3. Create a partial Java virtual machine  for the Prizm (not started)
4. Create Axe for the Prizm with an Axe legacy mode (in planning phase)
5. Develop a large set of C and asm libraries for the Prizm (some progress)
6. Create an emulator of the 83+ for the Prizm (not started)
7. Create a well polished game that showcases the ability of the Casio Prizm (not started)

32GB? Damn... For some reason that puts the PSP to shame...

Because Pro 2 Duos were ridiculously overpriced?
