(see zip-file in attachment with DOS-TC port of the AMIGA BASIC program)
I have used 1 ms in the delay and 1/18.2Hz timeticks in the sound
duration. (Info from Max Kargl )
This timing produces a session length of ca. 50 minutes.
So I guess I must reduce the delay timing.

Besides the wrong timing: Does the gnuplot-output look right ?
