Yamaha CS80

Ouf i have one section completely working . remaining calibration . 

one bad wave shaper chip . and one vcf ,  the calibration was so off that it was hard to tell what was working and what was not. 

So i will need at least  1 wave shaper ( ig00158 )  and 1 vcf ( ig00156 ) .  So far the only dead chip ( except cmos and op-amp ) pretty good for that starting condition . 

next time !
