Yamaha CS-80

via this auction
"This is the Yamaha CS-80, the mother of all polyphonic synthesizers. 220 lbs of pure juicy aftertouch heaven. This unit was purchased a few years ago from its original owner, Drew Arnott of the Canadian 80's pop sensation Strange Advance. There is still a 1980 sticker from Long & McQuade music on the back. My tech souped it up from parts of another CS80 & it has been purring like a kitten ever since. It has remained in a smoke-free studio, kept at 73 degrees F, and, miraculously, has stayed very well in tune. To that end, it features the later, more stable oscillator circuitry. You are intimate with the CS80's sound if you have ever watched Blade Runner or listened to Peter Gabriel's So.

The synth is in excellent cosmetic condition. All the buttons & sliders are functional, although, as always, a few of the bulbs under the preset buttons have burned out & I never bothered to replace them. Not pictured but included are the metal legs & casters, the lucite music stand attachment, the wood & tolex top cover, and, if you're interested, free of charge, the other CS80."

Note the patch memory below - four rows of sliders. You select the patch button corresponding to each row and edit. Each row is basically a mini version of the main panel.
