“This Casio CZ-101 is tested and working great. It’s used and in very good condition. A previous owner wrote “9V” on the far right of the keyboard.. to remind them what power supply to use I guess.
That being said, it is tested with a 9V power supply (not included) and works great. I didn’t test it with batteries but the compartment looks clean so it should be good to go.”
