It's about + or - 10 seconds away from five minutes. BTW, the five
minute timer apparently doesn't work when you're in zshell, since I once
left Tetris running for 2 hours accidentally (took a huge chunk out of
the battery power :-) ).
Another wierd thing about the timer--If you're in the edit mode of a
TI-BASIC program and you turn the calc off with [2nd] [On], and then turn
the calc back on, it puts you at the home screen, but if the timer shuts
it down, when you power the calc back up, it will be right where you left
it in the program editor.
