Casio SK-2100 80's sampler keyboard

The big kahuna of the legendary Casio SK sampler keyboard line. The only with full size keys. All keys and buttons function great, onboard mic works, takes line in/aux microphone great as well. The sample input level LEDS are stuck on full fo some reason, but it does not effect operation of the level slider or sampling in general. Some superficial bumps 'n scuffs from previous owners, along with some long-dried tape residue on the bottom. see video > https://youtu.be/_tfYk5HF5Hg
