I stumbled upon this article from two years ago, a neat summery of some of the early Walkmans. I haven't been able to find more on this page since it's originally in Japanese. https://translate.google.com/transl...naver.jp/odai/2142265326072002001&prev=search
Interesting it says :"At the Shinagawa station, the 35th anniversary of the Walkman is being held" I wish to attend something like this, Obviously this was log time ago but anybody knows whether or not there an exhibition of vintage electronics in Japan at any future date?
I had posted the 40th birthday for the Walkman, I have to believe something good will be happening. http://www.history.com/this-day-in-history/the-first-sony-walkman-goes-on-sale
