RMI KEYBOARD COMPUTER II w/ Punch Card Presets

via this auction

"Extremely rare RMI KEYBOARD COMPUTER II, recently serviced by Allen Organ. 100% working condition. Serial # 646 (pot codes date to 1975). This RMI KC II shares the same MOS-Board chip array that was recently purchased by the Smithsonian Institution because it was the first application of digital technology in not only musical instrument design but in all industrial manufacturing (1971), even pre-dating the digital calculator by several months. What is amazing is that these MOS boards are still running strong today and serviced by Allen, probably due to their robust military-spec design...very reliable for a vintage synth. This is a ground-breaking instrument and the model for other wavetable synths like the PPG wave. It may look like a combo organ but it is a 10-voice polyphonic digital wavetable synthesizer with IBM punch card reader. 15 original punch cards (choir, gong, horn, sine waves, flutes) are included as well as the original bound service manual with schematics. The user's manual is a copy. more images"
