Z80 fact: in order to keep the RAM intact, the chip must ALWAYS be
running. If the chip is EVER turned off, you lose your mem. With that in
mind, the backup battery must have enough juice to keep the chip active
(when halted). It may just run it at a slower speed.
The chip checks for [ON] being pressed 200 times a second, when the
calc is on or off. Why can't it run the tamagotchi too?
