I was just going through my parts boxes in the workshop and found a copy of the 1984 Yamaha Audio IC Guidebook. This was a book put out by Yamaha they basically lists 800 IC's with their Yamaha part numbers, their original manufacturers part numbers, and internal schematics and data for each chip. Too much to scan, but if anyone is working on old Yamaha equipment drop me a PM and I will scan any pages you might like to look at.
