Driven by Yamaha history
I have been a yamaha keyboard enthusiast for more decades than I wish to reveal. I only have about five keyboards remaining of the dozens I have owned. I am always driven to learn more about keyboards in general.
The amazing outpour of instruments is a challenge for anyone who is interested in collecting and understanding the value of older keyboards. This background brings me to the burning question. Does a definitive list exist which covers all the models Yamaha has produced?
