Re: Ti-89 Died

I've noticed mention of eeprom often: does the 89 have eeprom?
Shouldn't a high powered magnet be able to remove all viri from ROM?
Shouldn't the button on the back do that automatically (the one under
the emergency battery)? And if so, how come the emergency reset button
didn't work for me?
