Hi all.
I finally got hold of an original Yamaha service manual and will be
scanning it and putting it on my site (
http://therogoffs.com/cs80 ).
To whet everyone's appetites, I've already updated the scans of the
big, foldout schematic and block diagram. They are here:
http://therogoffs.com/cs80/manuals/CS80_Service_Manual. Yep, after
years of using the invaluable, but black-and-white scans online (done
by Crow or Kevin Lightner - don't remember which), you can now get it
in its full color (ok, two color) glory.
I'll be cleaning up the scan a bit soon, but it's pretty good now.
Enjoy,
David
