I'd like to join this request for info. I have a collection of Yamaha 
IC's myself, about which I already asked on AH, but I still have 
found no info on these last few:
the IG02592 and IG02611 mentioned above, and the
IG02590 - IG02600 - IG02601 - YM601 L - YM603 - YM605 - YM607 - YM608 
and YM614.

Any Yamaha IC experts here?  :-)
