“OU ARE BIDDING ON A ROLAND COMPU-MUSIC, MODEL # CMU-800. THIS IS A UNIQUE ITEM. THEY DO NOT MAKE THESE ANYMORE. The CMU-800 is a little four-channel mixer with internal preset voices and sequencer software for an Apple II or PC. There is a ribbon cable out the back with a card attached. It features analog synthesis with fixed sounds. Four note polyphony in the chord section, monophonic bass and melody synth sections, and an analog drum section.” Link
