|13-2-1B*||APPLE MUSIC SYNTHSIZER SOFTWARE
This is the music synthsizer that comes with the MC audio system.
|13-2-2A*||APPLE SONG TAPE 1
This is a single-sided cassette of 16 songs to be used on your MC music cards. The first eight are for 1,2 or 3 units, and the last eight are for 2 or 3 units. Titles are visible on the pictures. I've recorded both sides but side B is complete, side A has 15 songs only. You can also grab the two disk images for use with your MC system.
