Yamaha CS-Series Original Brochure - CS-80 CS-60 CS-50

via these auctions

"12-page brochure detailing the workings of the CS-50, CS-60, and CS-80.

I can't find a specific date for the printing, but it is brochure number 78610, so probably 1978. It's been in the archives all these years.

The first page is a foldout showing a large photo of the CS-50.

It devotes a couple of pages each to the different models talks about all the features, controls, options, etc. for each of the units, and has a block diagram of each on the last page. The back page is a comparison chart."
