Two Matrix-12s on the bay. One
here, and one
here. Title link takes you to more shots.
Update: consensus is that the auctions are both frauds. Check out the comments of this post. And note, I DO NOT put posts up for the sake of the auction. I put them up for the shots and details only. The auction links are a courtesy and the equivalent of via flickr, via YouTube, via joe, etc. It is not the purpose of these posts.
Some details from both:
"This amazing machine was the last of the great Oberheim analog machines; built before Oberhiem's acquisition by Gibson/Norlin. Computer controlled, with a revolutionary matrix modulation section and full midi implementation, it set a new standard for power and sound that hasn't really been equaled. Each patch features 12 voices. Each voice can have a different sound assigend to it. These voices can then be played polyphonically in rotation, or grouped by polyphonic zones. Or stack them all for a monster 12 voice monophonic lead to rock the earth! Via midi, you can even play every voice individually on it's own channel - it's like having 12 individual dual oscillator monophonic analog synthesizers, and at the same time having a 12 voice polyphonic 12 timbre synth.
# Audio Sources 12 Independent Velocity, Release Velocity and Pressure (After-Touch) responsive analog Voices. NOTE: On this unit, Release Velocity and Pressure are accessible only by external MIDI controller.

T sent the following into AH. I asked him if it would be ok to put this up here, and he gave me the thumbs up.
