A86: APD




A while back someone asked for the ROM call to the APD (so that the
calculator returns to where it left off after it's turned back on).
Well, this may be a bit of a hack, and I can't try it myself because my
link broke:
Since APD timer is located at $c00a, if we load this byte with 0 it
would be the same as if the timer ran out.  This alone won't do
anything, though, because the APD timer isn't checked while assembly is
running.  But, if you follow that by call _getkey, it should turn off
the calc.
