The Casio DG-20 was an "entirely new type of digital musical instrument which features the latest in state-of-the-art technology". Played with untuned nylon strings, the notes on the fretboard correspond to that of a guitar in standard tuning so it's a breeze to play. These are the MIDI functional models! 
Tested and working on power supply (not included), untested on battery power. Appears all original and is very clean.
