sted is a Vintage (1980) Casitone CT-370.
The Casio Casiotone CT-370 is a light, portable, but surprisingly sturdy, well-built keyboard produced during the late 1980s. Like all members of the Casiotone family, this instruments features many sounds and auto-accompaniments. The CT-370 can be powered via DC adaptor, or by six D-size batteries.
In the 1980s, this was still a big deal. Following to the right there's a series of five sliders: Power on/off, Main Volume, Accompaniment Volume, Rhythm Volume, and Chord type. While the first four are self explanatory, the fifth slider allows you to choose the way your keyboard is set up: you can have the full keyboard dedicated to one sound, with no left side auto-accompaniment, or you can set up two types of accompaniment, and the Casio chord feature (a simplified auto-accompaniment, where you press two keys and you get complex chords - useful for beginners).
See photos for condition, does not come with power adapter.
