Well there's not much to say. Though it appears extremely limited, coupled with a good sound editing program, one can create endless amounts of good sounds. It's fun to go insane and hit the keys randomly, yielding a sound somewhat like one would expect to hear coming out of an old school computer (Willy Wonka & the Chocolate Factory for instance). 1 1/8" output. Has a rockin demo, also. I know I've heard these casio beats somewhere...It's the kind of keyboard that everyone had when they were a kid and wished they had now.
Comments About the Sounds:
Only 4 sounds (piano, fantasy, violin, flute), but very thick. Good to sample and edit in sample editing program like Sound Forge because the sounds are so clear and thick.
(Thanks to Robert for this info.)

Quicker PT-1 MP3s Here is some high-adrenaline music created with the trusty old Casio PT-1 and 2 cheap Radio Shack Space Patrol walkie-talkies. Much more where this came from. Enjoy.
