In my case I can't use the Classpad 300 at school.......
But anyway I can use it at home thanks to the emulator

I've been raving about the Classpad to my dad for awhile now and so today he called Casio to ask them about it. First the people he called had no idea what the Classpad was, they had to look it up on their own web site to find out they had such a product (probably the reason it hasn't been advertised at all) after that they were able to look it up and found out that they would be getting a shipment from japan in about 2-4 weeks, so thats how long we have to wait to get them locally.
Got to love casio.

They'll probably do a larger campain at the start of or before next semester.. it's end semester now, and maybe not the best time to start pushing a new calc modell

The Classpad is much faster, more reliable, the CAS is tons better, and after a while.. at least for me, when working with my afx, I wanna start touching the screen and draging expressions around

sorry for the question guys......
I?m at www.claspad.de/euro/manager/ where I have to click to download the emulator?

I am loading the manual now but it is taking forever on dial up. Maybe yall can answer some questions for me since I wont be able to read the manual any time soon.
Can you type with the keypad or only with the on-screen keyboard with the stylus?
How fast is the processer? Not just the number of mhz but what other machines has this been used in so we can have a comparison. Do you know how this CPU compares to other calc CPUs?
What OS? A Casio OS or is it WinCE based like the canceled HP Xpander which seems to be pretty similar.
Can individual files be stored (TI style) or must everything be in Add-ins like the AFX?
How similar is BASIC to what Casios have now? Is it still like Casios and TI-Z80s where each command acts as a character and must be accessed from a menu or can you type in the commands from the keyboard?
Does it have an onboard assembler? ::drools:: ::doesnt hold breath::
What can we use on the PC to write machine code programs for it?
Does it have a speaker?
Does it support gray scale?
I have it's complete manual but unfortunatly i download it many times ago and i can't remmember it's original location.http://www.casiocalc.org/style_images/1/folder_post_icons/icon9.gif

Yes. it is an SH3 micro-processer ( and maybe it is better to say micro-controller) .
a part of manual:
--//
SH7729 is a single-chip RISC microprocessor that integrates a 32-bit RISC-type SuperH RISC
engine architecture CPU with digital signal processing (DSP) extension as its core that has a cache
memory, an on-chip X/Y memory, and a memory management unit (MMU) as well as peripheral
functions required for system configuration such as a timer, a realtime clock, an interrupt
controller, and a serial communication interface. The SH7729 includes data protection, virtual
memory, and other functions provided by incorporating an MMU into a SuperH Series
microprocessor (SH-1 or SH-2). SH7729 chip has the same peripheral modules as SH7709 but
with larger cache size, on-chip DSP module, on-chip X/Y memory, and emulator support. The
provision of on-chip DSP functions enables applications that previously required the use of two
chips?a microprocessor and a DSP?to be implemented with a single chip.
High-speed data transfers with a direct memory access controller (DMAC) and an external
memory access support function enables direct connection to each memory. The SH7729
microprocessor also supports an infrared communication function, an A/D converter, and a D/A
converter.
A powerful built-in power management function keeps power consumption low, even during highspeed
operation. This LSI can run at eight times the frequency of the system-bus operating speed,
making it optimum for electrical devices such as PDA requiring both high speed and low power.

i just copy and past that from it's manual.
but it is a really prowerfull processer! i really can not understand why casio use this so so so so so so S.O.S S.O.S S.O.S powerfull processor in a calculator!
TI just use a motorola 68000 processor! it is so old and very normal!
and a very very interesting thing about this calculator is about it's internal DSP (Digital Signal Processor)!
do you know why????!!!!
because casio built this calculator for schools! and i don't know witch student plan to use that !
there was some other models of SH3 processors witch does not have any DSP.
i think DSP is just usefull for BSD students and maybe university student( like me! )
that is really funny that casio just use this processor like very normal ones. (that is enough!) .
YES it has a small buzzer not a complete sound system. but i think that is enough to make some alarm.
i think someone should ask casio about the reasons that they made this calculator.
it is good to know there is a <{GNULINUX}> (Operationg System) for SH3 familly!
there is some bios for this familly too (it is like an OS but they called it Bios!)
witch casio use that to make its OS(CP OS).
unfortunatly i have not enough time to write more about calculator . i can just say it is really amazing thing in out hands! ( I bought CP to control my robots! not just as a very normal and expensive calculator!)
so please try to make it better and use it's powerfull processor not just as a gamepad!

But the information about the SH7709 may be used for programming (e.g. for timer manipulation), however I don't think the CP has got all its functionalities (I don't see the interest of having an ADC or a DAC for example )
