I believe Hammond released that synth in the 70s. I
saw one once where I used to take organ lesson at a Hammond dealer. I don't know
if it was manufactured by Hammond or if was manufactured for Hammond, but it was
all push button selected waveforms, filter response, enevelopes. there where no
knobs to tweak. A few years ago, Keyboard Magazine featured one in the "Vintage
Synthesizer Column". You might be able to go to their sight and check their
archives.
