Are there any rare prototype discs available?

Possibly. Although Mike does not remember ever holding onto any proto discs (and his entire disc archive was thrown in the trash a few years ago), I’ve had one report of a prototype Optigan “Cello” disc. The owner claimed to have acquired it from the Opsonar R&D department in the mid 70′s. It seems to me that this disc could very well have simply been a proto copy of the Orchestron Cello disc, but I never received verification of this from the owner.
