Yamaha CS80

I don't think the voice cards are the same at all.  I think they use a
similar topology but very different components and connections.  For
instance, I believe the oscillators are DCO, not VCO.  I could be wrong.
 But I'm pretty sure it's not 1:1.  I know for certain they use different
chips, as I've seen an old Yamaha pinout book for their custom chips and
the ones in the CS are different than those in the organs.
