Realistic Concertmate 650

Realistic Concertmate 650 Box

The same as the SK-5 except it was sold at Radio Shack.

Service Manual


There is an episode of "Arthur" (cartoon) on PBS where the intermission in the middle has some little kid jamming on one of these. It was pretty funny to hear my 3 year old daughter: "Daddy, he's playing one of your keyboards!" and she was dead on right :)

vickie  []  12/28/2010 04:39
Concertmate 660. In need of a manual as are a number of folks. If you have one and will send it to me, I will scan it to a PDF and make it available to anyone free of charge (and I will return your original to you!). FYI, there is no manual at the Radio Shack site and the unit is NOT the same as any Casio that I can find.
Tim Deaton  []  01/13/2011 06:42

Thank you so much for the manual. My parents found a Concertmate 650 tucked away in a closet and gave it to my 12 y/o daughter recently but it had no manual. She is going to flip when I give her the paperwork to go by. Appreciate this website!

I just bought a Realistic Concertmate - 650 at a garage sale (for a couple buck I might add). It works with the batteries and thank you for the operation manual. The service manual had an error and I could not download and print it. Also, do you know where I can get an AC adapter?
