We'll need to do a bake sale or something...
This would be quite ironic if the OTCalc project happened to be successful and all profits went on computers to factor the TI-Nspire keys ;D
Hey, that would be awesome.  Well, most of the profits.  We must reinvest. ;-)
I wouldn't trust TI, though. What if we factor the key and they decide to release a new Nspire hardware that won't run any old OS and use a different key? x.x
Won't happen if we break the Boot2 key.  It's not possible to change it.

If we need money for computing power, we could spread the word that we are trying to crack this key.  Cracking something this strong is a rare occurrence, and has significance outside of the calculator world.  Some people may be willing to help fund the effort, perhaps even RSA themselves.  Let's put together a good argument and publicize it!

would it be possible to give half of my computing power to breaking the key while still using the other half,
and have many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many many
people add onto it?

I love your enthusiasm, but this is not going to happen any time soon. We're still working on algorithms, though.

Yeah but I mean a totally new Nspire, like the TI-Nspire II or something, that would be very different from the ones we have now, different memory layout, etc. Wouldn't that have a different boot 2 or does all calc models use the same?

It would be counterproductive to Ti, so they probably won't do that.

So then we have all the nspire line cracked, and can feel 1337, then move on to crack the others later. If they're that different they won't bother calling them nspires. It would be the TI-nspire plus or something similar :P or the Ti-Nspire Explorer edition. Something incompatible

I have slightly revisited my idea, and I think it has some potential. Why? because this;
shows it. no this is NOT about cracking this is about 3D rendering. It's not the purpose I fancy but the way it is achieved. He uses a search algorithm to skim trough all that data to find out what needs to be drawn on the screen. Searching algortihms have greatly improved over the last years and basically my idea was a very, very rudimentary search algorithm. I am suggesting not to count up every possibility from decimal 1 to 8,9884656734115795386465259539451e+307. Instead of doing that I suggest we start to search from the middle, then from the middle from the middle (both on the left, and the right side), then the middle of the middle of the middle (making 4 middles in total by now) then the middle of the middle of the middle if the middle (8 middles and counting) etc. It would be best if each of these is calculated to be correct or incorrect in parallel, that's where FPGA's kick in. :D

Anyways the sheer size of this problem I think prooves, N!=P

matthias1992, that would be exactly as efficient as a routine that counts from 1 to 89884656734115795386465259539451e+307.

But it is more likely that the factor will be around 512 bits, so the algorithm should start around there.

correct and incorrect at the same time, yes it will do the same things but one will more likely come accros a correct value, altough I must admit that, that last statement is just intuition. yes I do use intuition, I suck at math, really.

it's not really as efficient.  If you used it to find better bounds on where to find the prime, then maybe, but there is no function to find if the prime was in a range. If there was, this would be so easy.

I was thinking, if I could convince my School district to run a server, could someone whip up some software to run on this massive computer? I think I can convince them via the "big deal, famousness" angle. the server even has the facilities to reset every computer in the district from one location!
