Bil Herd and the Buchla

After my recent build of a Buchla 208 clone (one 1/2 of the Music Easel) revealed some problems and after gazing ineffectively for hours at the original 1973 hand drawn schematics like they were some kind of Magic Eye puzzle, it was time to call in the help of the pros.

Fortunately, I had just met legendary electronics guru Bil Herd (Commodore, Hack a Day, Herdware). After getting familiar with the ODD (Old Don Design) Buchla layout and functionality, he had the problem isolated in no time: a missing trace from the Enable A from the Envelope board to the Enable A to the Pulser board. A little Telfon wire later and I now have a working 208.
