{All LoringWare products are dedicated to the memory of my Grandfather,
Loring E. Tyson. He was a scientist and teacher, and he was my
inspiration and mentor in the areas of science and technology.
September 3, 1903 - October 21, 1978.
This program was written to assist in troubleshooting the audio section
of a computer. It produces an 880 hertz beep 1/20th of a second long, once
a second. Running TONE gives you an audio source to trace through the audio
section of the computer under test.
