Out of interest..?

2010-01-20 by Quazimodo

Hi everyone,
Was wondering if anyone here could maybe answer a small qustion I've been curious about. The CS80 uses 2 different chips for the VCF and the VCA envelopes (152 and 159) but the CS70 uses the same chip for both these jobs - the 159. What would happen in an '80 if you replaced the VCF chip with a 159?

Looking on the schematic they have identical pin-out 'names'..!?

Cheers,
TOM
