[sdiy] Roland Promars second oscillator schematics?

[Steve Lenham]

Does anyone have the schematics for the Roland Promars (relatively rare 
monophonic version of the Jupiter-4)?

I'm interested in the unique second oscillator board (not shared by the JP4) 
and it's associated CV and detuning circuitry - seems to me that it would be 
rather nice to replicate that facility four times over for my JP4 (still 
badly in need of restoration but making some super noises; four-note 
polyphony is plenty when one hand is tied up holding down a non-latching 
voice select button...).

Thanks very much for any help,

Steve L.
