Kurzweil 150 K150 Fourier Synthesis synthesizer module SN 87030281

via this auction

"KURZWEIL K150 Expander additive Fourier Synthesis synthesizer module for sale. Manufactured by Kurzweil Music Systems, Inc. of Waltham, MA. Made in USA. I didn't test every function of the synthesizer, but it does sound good and cycles through the onboard sound programs with no problem. The volume potentiometer is scratchy and pops a bit when adjusting but otherwise quiet once adjusted. This K150 has "K150FS V1.7" eproms in sockets U55 and U57 of the CPU board which - if I understand correctly - will allow its 240 sine wave oscillators, filters, envelopes, etc. to be programmed independently with Kurzweil's K150 Sound Modeling Program using an Apple IIe computer with Passport Designs MIDI interface card. Chassis is solid and well built. Its black paint has chipped off around several panel mounting screws and also has the usual scuffs and scratches, otherwise, finish is fair. Includes "K150 User's Manual" and "150 Fourier Synthesizer Sound Modeling Program for the Kurzweil 150FS and the Apple IIe Version 1.0 User's Guide" and copies of other K150 manuals, addendums, appendixes, lists, etc. Sold as is with no warranties. Buyer pays actual shipping cost. Will be shipped with signature confirmation upon receipt. Package's dimensions and weight are 24" x 24" x 12" and 35 lbs."

  1. If only I could hack in and make this disappear. Then no one would buy it and the price would drop. (Wrings hands and chortles.)
