Set: Music - Instruments. Casio once had some professional products. This one is warm sounding, once so popular Casio FZ-1 Digital Sampling Keyboard (1987). Sorry about the dust... 61 keys. 16-bit. 8 channels out / mix out. Mono mic & line in. MIDI in/out/thru. 3.5 disc drive. 2 Mb memory. SCSI port for connecting to other Casio keyboards (might also work with hard drives). Big backlit green display. Easy to use / edit samples. Also can be used as a synth using simple (CZ-1) waveforms. Weights a ton! I got this one back in 1992. It has seen better days, but it still works ok. I used it in live performances over the years. And after that it served as a master keyboard at home. Now I have no use for it.
