SAN FRANCISCO - An Apple-1, a rare model of the first computer produced by the now-iconic tech firm, fetched $375,000 in an auction this week, according to Boston-based RR Auction. The computer was among 175 of those sold by Steve Jobs and Steve Wozniak from their production in a garage in Silicon Valley in the early days of Apple in 1976 and 1977. The model originally went for $666.66 when it was sold by the Byte Shop computer store in Mountain View, California in the 1970s. Jobs and Wozniak initially designed the Apple-1 as a bare circuit board to be sold as a kit and completed by electronics hobbyists, but Byte Shop owned Paul Terrell agreed to buy 50 if they were fully assembled and did not require soldering by the buyer.
