Check out the collection of Apple kit owned by 15-year old Alex Jason. The video below is from 2014, but his collection has expanded to some 200 machines, including an Apple I, a Lisa, all of the Newtons, an Apple mouse prototype called the Cursor III, and more iMacs than you can shake a stick at. The New York Times did a story on the collection, which will form the foundation of the Maine Technology Museum. It's an incredible collection.
