A planned technology museum in Maine grew out of the curiosity of a 10-year-old.

In 2010, Alex Jason traded a minibike and an electric snowblower for an iMac G5 computer, in what turned out to be the start of a giant collection of vintage computer equipment, including 200 Apple machines. It is one of only a few dozen collections of its size and kind in the country.

Alex, now 15, along with his father, Bill Jason, are planning to display the collection, known as Alex’s Apple Orchard, in a converted library in Fairfield, Me., soon to be the Maine Technology Museum.

Among Alex’s pieces is a rare Apple I from 1976 that still works and has the original chips. Fewer than 70 of these models are believed to remain, with one selling for more than $900,000 at an auction in 2014.
