This is the part you get to type in by hand if you
|
|
have no other way to communicate to a machine.
|
|
Begin and end addresses are two-byte LSB/MSB pointers
|
|
in $3c/$3d and $3e/$3f; they are loaded for you from
|
|
$301/$303 and $309/$30b if you just want to call
|
|
the entry point at $300. Otherwise, fill them in
|
|
directly and call the WRITE entry point at $346.
|
|
|
|
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.)
