Again, I suggest we take the road where iOS jailbreaking has done - "new OS update? Great! Let's hack it again!" The JB community there doesn't even bother to convince Apple. Sure. But the iOS, Wii and whatever similar jailbreaking communities are doing a much better job at near-uninterrupted arbitrary native code execution availability, and about breadth of usage of the platform, than we are doing. Again, I am including myself in the criticism. That's why I wrote above that hardly anybody cares about the Nspire platform  The reason the iPhone hacking community is doing better is that the iPhone has so much more hardware/software capability. Also, the underlying UNIX OS makes it very attractive. The Nspire was marketted to the classroom - so a budget limit plays a design factor compared to the iPhone.

Just imagine what could be achieved on production Nspire if someone managed to connect that pin...
Or, how was it programmed without that connection ? Edit: Maybe by production time they were programmed on a machine in an assembly line fashion, then soldered on the board .

easier yet:
debug> w nspirememory.bin 10000000 2000000
Then you dont have to look at the rest of the emulator code only what you are interested in.

Another way is to open and load any file into a high memory location and use the debugger dump utility
The attached program does that, and breaks into the debugger for you.
You will have to concatenate the files made.

Basically do those have to run the same OS as the calc they're hooked to to function?
Apparently not. My CX (os3.1)detected the prototype cradle and the Vernier software came up immedialely A voltage sensor seems to be the least expensive to get.

I bought it as a touchpad/cradle combination for a the price of a used touchpad It seems to work fine but I dont have any sensors for it.

Prpbably because not very many people where using it.
It is included in Ndless 3.1
Here they are, you will have to make a custom syscall.
0X102F6A70 os_ncas2.0.1
0X102F7A40 os_ncas2.1.0
0X102F7340 0s_cas2.0.1
0X102F8310 0s_cas2.1.0

Try press and hold the space bar on the Hyperterminal side while rebooting, to see if that
brings up the U-Boot shell.

I don't care my programs being shared on any programming site, but one of them is an early alpha version, that is not ready to be shared yet :s ! ... I mean, you can share it, but there's no interest and it does not show the quality of the final production :p !
Edit: Actually, there are 3 programs of mine, and all three are betas ... 
This is an excellent example of why you should post your source code with your binaries in an open source forum. 1)People wont assume its a final release. 2)you get feedback for improvements 3)Others can port your code to newer calculators, while you left for bigger and better things. Case in point: If Mraklopaz did not leave his source code for nDoom we would seen it in color on the TI-NSpire CX and his name goes on as the original author - looks good on a resume to me !!! How many of those 9860 programs listed bove will be ported to the Prizm ? Last time I was on CasioKingdom not may addin programs came with source.

Hello guys,
As stated in the subject. I can't use this:  since that only works for x=-1 through x=1...
Who knows another summation/computation algorithm? Thanks!
(x-1)/(x+1) +1/3 * [(x-1)/(x+1)]^3 + 1/5 * [(x-1)/(x+1)]^5 + 1/7 * [(x-1)/(x+1)]^7 ..... for x > 0 There are shortcuts on a calculator to do this.

I have a version of this working on the Prizm .
It already does syscalls, and I have not released it yet.
I will get back to this at some point.
I need to make a good demo out of it.

Amazing !
Is it stable yet ?
It is still buggy, but it is running.....

At any rate , if someone supplied the schematic diagram for that chip with all connecting components
it would not be worth the effort for most people to modify.

R02D is a resistor - should be able to solder that .......
Dont know the size of the resistance.

It seems CASIO isn't too open about how to update their OS.... their update process is encoded inside the MSI! O_O
The update process does not extract any useful files, and the updating is done inside the MSI.
(InstallShield self-extracting EXE -> InstallShield MSI -> OS Updater inside MSI)
I've dumped the MSI's contents for those who want to try to find a solution.
http://dl.dropbox.com/u/1016340/MSIDump.zip
In OS 1.02, I believe that the OS was contained within the OSupdateDLL.dll file, and a program was written to extract it. Is this DLL file still present? I haven't been able to look at the 1.03 MSI yet.
I think that program has to be rewritten , here are the resources I found in that dll: 3841 3842 3843 3857 3858 3859 3860 3865 3866 3867 3868 3869 3887
