Before the iPod, Discman there was Mister Disc which came in 1983 and most probably never made it to the public. Developed by Audio-Technica it was a portable stereo phono system which allowed you to listen to vinyl records anywhere anytime using the earphones. It was powered by internal batteries or AC power. Unfortunately it could not be used while moving and had to be kept on a flat surface for playback. Though it may sound like a dud but 24 years back in 1983 it would have been the coolest thing after the Walkman that is.
