; This is a small sound example for the IBM PC
; It will play 12 notes of the octave starting at middle C.
;-----------------------------------------------------------------------------
; How to generate sound on the IBM PC :
;
; The 8255 (port 61H) bit 0 controls the 8253 timer
; bit 1 controls the speaker
;
; The output channel 2 from the 8253 timer will be ANDed with the
; speaker control bit in order to turn on/off the speaker.
