[sdiy] Buchla 200e

[mark verbos]

 From what I understand, when purchasing a 200e you enter into an 
agreement about keeping the circuit a secret. Like, no scanning of the 
PCB. ;)

I did get the chance to look at the insides of a 200e. I was shaked to 
see that the 259e oscillators are a single board with the panel 
components and everything else all attached! The circuit uses a micro 
with A-D and D-A converters to get the data to the outside world.

I suspect the 261e may have more circuit to it, having an analog 
waveshaper and all...
