# Casio SK-1
“For sale today is this nice Casio SK-1 keyboard. All of the screws are missing for circuit bending purposes, and, although it has the battery cover, they tended to slip out, so there is a small taped fix in the inside of the unit (not visible when closed). It functioned great the last time I used it. It’s in great condition, especially for being vintage. This auction does not include the batteries or adapter.” Link
