I'm pretty sure he is a senior in college though

I just tried something new. For me I have a quad core proc. What I did was make four folders each containing the program and persist.data. For the first persist it was 60... the second 64... the third 68... and the fourth 6C...
Now I use the entire CPU potential instead of 25%

Sounds good  if you really want to, this program only sets its priority to High, you can manually set it to realtime from the task manager 
I will do that. And what if we made this a competition to see who can test the most keys in a month? Edit: number of posts in a year, 365

I just transferred this to my more powerful computer, overclocked the cpu, turned all fans to high, disabled all background apps, and hoped my power bill won't be too high.

Maybe I could try to expand education some way with the Prizm. Also if uberspire was under 18 he could've submitted his new calc.

Every platform that it would be reasonable to run a key factoring program on.
Maybe z80 isn't reasonable enough, but SH3 could add just that little oomph of speed needed to factor the RSA. And Java is not fast enough.

I want in. but how do I develop an epic project for the Prizm, in under a month, that benefits humanity as a whole  I have the emulator, but that probably won't be done until summer and only benefits a select group.

I see, that's interesting. Hopefully it shouldn't be too hard. Remember that the Prizm is 16:9 ratio instead of 3:2, though, so if you fill the entire screen with the 83+ LCD it will look distorted.
The 4x3 ratio uses up the entire screen horizontally, but leaves a bar at the bottom. That could be used for fps, clock speed, debug info, or some sort of user interface. And this Prizm emulator I have been working on lately really helps me appreciate the simplicity of z80 asm. I am almost certain that an on calc z80 emulator will be a lot easier than an on comp SH3 emulator.
I think a 3x3 ratio would be better - stretched screens can look quite odd.The only things I'd imagine you'd have a problem with are hardware things like paging.
Well the 83+ writes to the flash pages sequentially. A possible example would be to only reserve a page from the Prizm OS when the 83+ OS passes into a new one.
RAM is paged, too.
3x3 will work, but will leave the a large part of the screen unused, but it all depends on how each result looks. For the ram, that can be accomplished by changing offsets depending on which pages are addressable.

Update: To convince everyone that i'm not slacking off on this project. I am posting the entire project source as of right now. You will notice first off that you cannot compile the code yet because there is no main function. You can however review the code, which I am trying to keep well commented. The most interesting part is "instruction set.h" as it contains the emulated source for each machine instruction. Right now in the code, 9 of the instructions are fully written. 18 instructions (viewable in the source) will be included with the first release (hopefully this weekend). You will also notice that a file called spectrum.cpp is missing. Spectrum will be the official name of the project when I release it. With the first version a user will be able to upload a pre-compiled program (no header) and run that. There will also be a gui (I will be working on that later), that will display the current contents of the 16 registers and the cpu speed. Lastly there really isn't a whole lot left to code before the first release. Enjoy the source for now.

Sounds like it could be kind of hard to calculate as each instruction has varying size from only one byte to several hundred or even thousand bytes. You could have the subroutine count the number of carriage returns to find where to jump to.
:15->A //number of instructions to jump
:asm(JUMP //count 15 carriage returns, then change the BASIC pointer to that address.
:blah //14 lines of blah
:if B=4 //destination

If I had to make a guess, is it four screws in your neck? Ughh, it just sounds painful saying that.  Glad it doesn't bother you anymore.
