An Apple-1 device like this sold for more than $900,000 ($1.1 million CAD) in 2014.

The company founded by Steve Wozniak and Steve Jobs built a total of just 200 Apple-1s, all assembled by hand at Jobs, most of which were sold at the time for $666.66 ($829).

According to expert Cory Cohen, who interviewed him Los Angeles Times, 60 Apple-1s have been listed so far, but only 20 of them, including the one sold by John Moran’s home, are still operating.

The model is more authentic because it has an exotic wooden case, the koa, which is native to the Hawaiian Islands. There are only six known examples of Apple-1 with koa dwellings, according to John Moran’s home catalog.

In 1976, Apple-1s were among the first models of personal computers that were already assembled, with components already soldered to the motherboard in particular, but often sold without a case or keyboard.

The copy sold on Tuesday was purchased by a professor at Chaffee College. He resold it in 1977 to one of his students, who has kept it to this day and has chosen to remain anonymous.
