Used vintage Casiotone MT-68. TESTED AND WORKING!
MISSING/DEFECTS (CIRCLED IN RED IN PHOTOS):
It is missing several sliders, knobs, battery cover, and AC power adapter.
The power switch is functional, but needs a screw driver to be turned on/off.
The keyboard has been tested on battery power and works without issues.
Message me if you have any questions!
Thanks for looking.
