What was the first personal computer?
is a plastic mechanical computer from the 1960s. It offered three bits of tabletop computing, back in an age where corded telephones were considered high-tech. The machine arrived in kit form; your first task was to assemble the jumble of tubes, rods, and elastic bands into something that resembles a Jetson’s parking garage. Once complete, it’s a fantastic hands-on way to teach Boolean algebra and binary numbers.
