- From ACS to Altair: The Rise of the Hobby Computer (technichistory.com)
A certain pattern of technological development recurred many times in the decades around the turn of the twentieth century: a scattered hobby community, tinkering with a new idea, develops it to the point where those hobbyists can sell it as a product.

Bicycles, automobiles, airplanes, and radio broadcasting all developed more or less in this way.
