# Buchla 500
“Re-listed with BIN, due to non-paying bidder.
I’m also opened for trade with old synthesizers, modules…
Extremly rare BUCHLA electric music box series 500 modules. ….only 3 exemplars ever made in the world!!! The cv interface module need of PSU and computer facilities … I’m convinced that the joysticks and trigger, control voltages module can drive other modular systems with a right psu of course, they have a Cinch Jones plug for Power Supply and a pair of facilities connectors in the rear part. I don’t know the right voltage that they need, I haven’t any schematis.. I bought them for collection but ..I think they need of a new home with other Buchla brothers 
Amazing: the two joysticks are photosensitive built with optoisolators ..so the sticks are luminescent…a primitive but charming devices! Shipping and packing costs to Europe are of 34 euro about. Spedizione e imballaggio in Italia: 14 euro ” Link
