It's built into TI's keypress handler, which is an interrupt.
Why, I don't know.

Yes. Penguins uses it's own interrupt handler. Notice it
doesn't work in Penguins.

The OS will not operate with interrupts disabled. You
could only do it during games. You would have to re-
enable them before returning.

No, it's software. And it doesn't slow it way down. It
stops it and slows other interrupt functions (like the
cursor blink or busy indicator) way down.

Not all 5. Just one of the AAA's. Unless the [ON]
interrupt handler is corrupted (the [ON] interrupt can't
be disabled), you can always reset your calculator
without removing more than one battery.
