In the 1970s, a young man named Steve Wozniak made something no one had ever built before.He created a computer "motherboard" that did not need to be put together by the person who bought it.Earlier computers required buyers to assemble the motherboard -- the main circuit board, or system board, found in computers.The computer Mr. Wozniak built became known as the Apple-1. The age of the personal computer had begun."The Apple-1 changed the world and defined the world as we live today."That is Christian Overland. He is vice-president of The Henry Ford Museum in Dearborn, Michigan.Last month, museum officials purchased an Apple-1 computer at a public auction in New York.They paid $905,000 for the device, which is one of the first 50 built. And it is still working.The auction house that sold the computer believed it would sell for one-third to one-half of what the museum paid for it.In May of last year, an Apple-1 sold for $671,000 in Germany.
