Don’t retire that faithful old cassette recorder into the closet after you upgrade to a disk drive.
Use it to play a music soundtrack or voice narration controlled by your BASIC programs. The sound
will come out of your TV or monitor speaker.
Insert a cassette recording into the drive and press the Play button.
Whenever you want the soundtrack to start, cue it with a program line such as:
10 POKE 54018,52:REM TURN ON CASSETTE MOTOR
When you want to turn off the sound, use this line:
20 POKE 54018,60:REM TURN OFF MOTOR
