"If you own a CS80 and you don't have this document you are incomplete."

Description for the Manual:

"Here is a rarity.. The original manual for the iconic Yamaha CS80 Polyphonic synthesizer dated February 1977. This would have been the manual shipped with the very first units.

I got this with my CS80 in 2001 and recently came across it in a pile of documents I will be listing for sale over the next week. I've seen the 1980 manual online but this is the only one of these I've seen in 20 years of obsessing over these instruments. It's in ok shape, its a 42 year old document and shows some age as you can see in the photos. I have kept it flat, wrapped in a mylar magazine bag to preserve it as best i can. It's 20 pages cover to cover, it has some stains, a rip and isn't perfect but is what it is."

Description for the Brochure:

"Although not as obscure the 1977 owners manual, this document is rarely seen, particularly in this condition. I've seen lesser quality copies of this fetch document my asking price on ebay over the years. Dates to June 1977 (7726)

Looks like your standard preset toy synth, but this one appears to have a headphone with mic, and a mini DJ style jog wheel like the Roland DJ-70. Could make for some interesting circuit bending fun.

"STEREO FIELD is one instrument with three uses. It is simultaneously a stereo/quad modular touch plate feedback atonal synthesizer, a stereo/quad audio processor and a pressure sensitive chaotic CV "controller". All three uses are available separately as well as simultaneously and in conversation with each other. The Stereo Field allows its user to manipulate and patch two analog stereo preamp circuits via touch plates. By utilizing skin conductivity as new paths for current to follow you are creating "new circuits" and new sounds in relation to where your fingers are patching. The individual touch plates are directly connected to nearly every connection point of every component in its circuitry (located directly under each corresponding touch plate). When touched with multiple fingers it will create atonal analog feedback with either of the two mirrored circuits represented by interlocking touch-plate circles."
