Well, even if we found it would it be so easy? We don't even know where they started, or stopped at!

At least close to the nspire, maybe only 80 mhz instead of 150, either way it'll be great. The nspire sucked because of its OS, mostly.

Why? Because it's not going to follow an algorithm? Those vary anyways.

TI only needed to generate a few primes, though, to make the key. Their job was relatively easy.

That Omnicalc RAM restore, does it just stick a backup in archive? That seems like it would work well enough, but I really don't see the point. The OS can do that by itself with the group function.
There was something similar for the 86 (much more useful, since the 86 had no Flash ROM) and it used the extra RAM that pterodactyl gives to the OS. Phoenix also used it to save ![]() ![]() 2544

When running an Nspire, having something on homescreen, swap keypads, boot, then swap back (I actively use both, surprisingly enough) and occasionally the homescreen will be partially cleared, partially still full of text.

I'm guessing it's a spring problem, considering how people describe it as a loose keypad. Fortunately, I don't have the problem myself. They should make it be held in with a better latch, and no spring.

Well, the idea they're saying is that you make a boot2 that has an RSA key (which is a semiprime, the product of two primes) that you know the two prime factors of. This allows you to make your own OS. I was simply stating that a semiprime that is closer would be easier to make a hash match than one farther away from the original.
Example: 17*11=187 original key 11*11=121 as a replacement would not match the hash as easily as, say, 17*13 which = 221. You can get closer with larger numbers. 2549

Ah. Darn. It'd be even harder if you used rechargeables, since their voltages behave so differently when draining.

Probably around the same. Of course, an extremely similar file would be much easier to compute than an extremely difficult one, and if we made the boot2 simply accept our own OS's key (which could be an extremely close semiprime number, but one we know the factors of
