This is the part you get to type in by hand if you
have no other way to communicate to a machine.  
This version swaps in slot 2 and dumps memory from
$C800-$CFFF.

When the sound output is complete, a "Z" will be 
printed and you'll be back at the prompt.  (The
original monitor code would print a Ctrl-G (beep),
which is not desirable now.)
