A89: Forming a group to hack 89




    As I see it we have more than on possible recourse for TI's actions.
There are, however, some things that would not be worth our time. The main
on is cracking the 512-bit encryption, as this would take _much_ to long.
So, without that our hardware version 2.00 friends are seemingly screwed -
unless we make a program to remedy this problem. I believe there are 3 ways
to go about this:

(1.) Make a program that executes strings*.
(2.) Make a Flash Application that copies a string*.
(3.) Make a program to "jump" into a string* as if it were code.

* (or other variable)

    We would have to do some work to find out if some of these are even
possible, but that hasn't stopped us before. If we would be able to get any
of these to work, then we will obviously be able to run larger programs.

    Another problem is these "Flash Applications". There is _no_ way that I
am _ever_ going to pay for calculator software. The hardware version 1.00
people will be able (eventually) to change their serial number, allowing for
wonderful piracy of applications. This could actually help hardware version
2.00 users. Since there is no way that the calculator decrypts the Flash
Applications every time it is run then it should be possible to find a way
to copy the code only of the application. This would then be sent the to the
hardware version 2.00 users. The only problem with this is that without one
of the programs that would run code over 8kb, well lets just say that would
really suck. Even if one of the programs above was developed there would
still be a limit to the size (non archive memory).

    If anyone would like to join me in trying to do one of these ideas, or
something else, e-mail me at webmaster@communitycrc.org. If you do e-mail
me, please state what you would be able to do (program in asm, c, or
whatever) and I will get back to you with a list of people interested and
some more ideas of what we could attempt to do.

Sincerely,
