Yamaha QY-100 in good condition. This is the hand-held sequencer/tone module that a lot of people used as a sketchpad before laptops took over — 16-track sequencer, hundreds of onboard voices, arpeggios, and a built-in guitar-chord input mode. Includes a 16MB memory card and the power supply, so you can save your work and leave the batteries out. Condition notes: - Some velcro on the back - Normal wear for a unit of this age (see pictures) Everything works. Fun little box if you want to write away from a screen.
