Yamaha CS80

Hi all.
After fixing a wonderful CS60, in great esthetic condition that I am going to sell, I find myself with a plenty (but never too many) of precious spare custom ICs and a few IG00151s from spare boards, previously bought. 
If anybody there was interested, I can swap one VCO IC IG00153, 2x VCFs IG00156, one IG00159 and other rare ones. If you are in need of  these, please make me offers. I DON'T want to sell, only trade (not even, obviously) with IG00151s.
Having this machine opened, I can test the ICs I am going to trade, the same I'll do to test the ones that possibly get for trade. 
If you want i can swap a semi-complete voice board M for a TRIG board from a working CS80.
Ciao
