Here in is beep!  Beep is a demo program for the MM/1 only that beeps the
internal speaker while ramping the frequency.

Don't be alarmed by the "System state process" as I did this so you cannot
kill  your machine while running it.  The normal bell will not be audible
anyway and killing it leaves the beep active (I'll fix that someday.)
