MIRACLE PIANO TEACHING SYSTEM KEYBOARD MAC (NINTENDO NES) COMPATIBLE - FOR PARTS. Condition is "For parts or not working". It has the power supply hardwired inside it with an on/off toggle installed. It does turn on and all the various buttons work and keys work, except the volume up and down buttons do not seem to change the lights showing how loud it is set to. It has the usual scuffs and scrapes from use. It does not include a pedal or any other accessories. It is missing the label wth the buttons marked and Nintendo seal on the top, as that was sold to someone who needed it for parts. I have tried to describe this in a way that you fully know what you are getting and have provided pictures to help you make a wise choice. We ship the same business day in most cases.
