An Apple-1 computer, that was hand-built by company Founders Steve Jobs and Steve Wozniak in 1976, has been sold at a US auction for $400,000 (nearly ₹3 crore). The computer was originally purchased by a Chaffey College professor, who later sold it to his student in 1977 for $650. The Apple-1 computer is reportedly one of only 20 still functioning.
