Does anyone have the schematic for this monster?

I dont but would love to have it.

I have a PDF of the original schematics. There is a common schematics with a table of the part values for all the filter cards. The motherboard schematic is pretty low resolution and not of much use. It is on my Buchla 296 page.

Thank you Dave thumbs up

Attached what I have so far in my Eagle file.

For the Freq and Width, I've got some window comparators in. The idea is to take the Freq CV, add the Width CV to get the upper limit, and subtract WidthCV from FreqCV to get the lower limit. These limits are checked in each filter against the reference voltage for that filter, to see if it's within the Upper and Lower limits. I still have to put in the circuitry for the Freq/Width CV generation.

The filter resistor and capacitors are probably the right values, but I wouldn't be sure about anything else.
