The apple plaintalk microphone jack used on some older macintosh systems is designed to accept an extended 3. 5 mm three-conductor phone connector; in this case, the tip carries power for a preamplifier inside the microphone. The sound a rather fast repeating beat i made using an apple plaintalk microphone in a rather modern windows laptop using audacity. I messed around with the jack, and took out all the silent parts.
