This quite rare small keyboard from 1987 (embossed case date stamp) is one of the successors of the famous Casio SK-1 lo-fi sampler. It can store up to 4 samples (playable through drumpads or keyboard) and keeps them in battery backed- up memory after power off. In opposite to the SK-1 it includes a “melody guide” key lighting feature for music teaching (not the keys itself light up but a row of small LEDs above them) and a ROM- Pack music cartridge slot. Unfortunately this instrument is missing the nice drawbar synthesizer and portamento of the SK-1, and the tekkno blip drums were replaced by ordinary percussion samples without accompaniment. Also the sequencer is way simpler than on SK-1. This instrument was also released as Realistic Concertmate-800. By a keyboard matrix easteregg the SK-8 can be easily modified into an oriental keyboard.
