Casio CDP-S100 specs
Casio's bare-bones 88-note piano: 64-note polyphony, 10 tones and an action the manual describes only as an '88-key piano keyboard, with Touch Response', with no hammer-action name given anywhere in Casio's documentation. Neither a dated announcement nor a dated discontinuation exists for it. At 10.5 kg with battery power (6 x AA, about 13 hours) it was one of the most portable weighted-style boards of its run.
