Someone has a whole web page about that. Basically, from memory, this is how
you can screw up your calculator w/o DoorsOS or anything:
Reset your Memory
Set graphing mode to 3D
Go to the Y= editor, then type rand() for z=
Graph it, hold the right arrow to animate it.
Press | twice to add contours
Graph will be invisible, and BUSY signal will be grey/flashing
Go to ZOOM and Zoom In
Graph is now really odd... it's all spotty and lines are going all over the
place
Go to the Y= editor again. You'll either see funny symbols or the calculator
will crash.
Graph it again, then zoom back out.
Go back to Y=, and the screen will screw up. Congratulations, your calc is now
messed up! Take out a battery and hold ON for a few seconds to reset it. If
that doesn't work, take out more...
Just to CYA: I'm not responsible for anything this might do to your calc, your
data, or anything. This is soley for entertainment/educational purposes.
