RE: A86: Tamagotchi?
Yes, but how would it know what time it was when the calc was turned back
on? The only ways are asking the user for the date and time (best way), or
having the program run in the background when the calc is off (major waste
of batteries). There is no internal clock in any of the TI calcs.

I don't know that much about asm, but couldn't the program be set to halt
itself when you shut the calc off, that way preserving your batts, and not
dieing while you go between classes or sleep at night, somewhat like the
way a real tamagotchi sleeps all night so you don't have to deal with it.
