Hi everyone,
I have a question about the early Moog Modular 901a/b Oscillator Controller/Driver.
The cicuit diagram can be found here at the Moog Archives here:
http://www.moogarchives.com/ (click 'modules' on the left)
Looking at the cct diagram connector pin-out, there are 'A' 'B' and CONTROL NODE pins.
Now, the 901b Oscillator connector pin-out has an 'A' 'B' and 'C' - would the 'C' interface with the CONTROL NODE pin on the Controller/Driver cct?
Also, the Controller/Driver connector shows the 'Width of pulse waveform' circuit between pins 6 and 13 - but that seems to be it - pins 6 and 13 do not appear anywhere in the circuit... where does this pulse width circuit interface to..?
I hope someone can shed some light on these mysteries.
Thanks in advance,
Tom

This also happens to be the "c" connection designation.
"Control Node" is for external control, for example through a CP module routing the keyboard voltage to the VCOs.
