Hi David,
Of course I'm aware of the two sites you mention. I have browsed them both more than once. Without them, my project would certainly not be well under way as it is today.
I want to share my reworked CS-80's overall circuit diagram with the people interested in studying it. The original printed version has so many errors (just to mention drawing errors or oversights), I can't count them. I fixed most of them with the diagrams of the service manual and the circuit boards. Working on the interactive diagram for the site, lately, I still found a few errors (less important, but errors anyway). Sometimes, the layout is unduly complex (but all was hand-drawn then). I try to make it more immediately understandable.
I just uploaded the interactive diagram. For the moment, only one third is interactive (the left part).
I hope it will be of some help for newcomers who wish to understand the inner working of the beast.
Joachim
