Stereo -A 2 Channel Music Program
8-403

Maurice Retter, University of Oxford, Oxford, England

A musical program, written for the PDP-8, which can control
two loudspeakers independently. A frequency is produced by
creating a square wave pulse train, where each pulse is generated
by an lOT instruction, and the time delay between
pulses is under program control. Two channels are made
available, if required, by using two IOP pulses from one lOT
instruction to activate independent loudspeakers. The program
is divided into a coding section, and a decoding section and
play routine.
