There is scant info on the interwebz about this, but it looks intriguing, if only for its rarity. A DIY kit of some sort, I'm guessing. If I had $$ to play around with I would try to win this auction. Info I found places it around '68 or '69...but as a synth it has very little control. Curious how it sounds, though. Apparently Schober also had a very early drum machine that could be played and triggered with an organ instead of just playing back preset rhythms.
(Someone get this thing!)

This probably belongs in the auction list page, but I thought it was interesting enough to post here.
