An original Apple 1 computer motherboard sold this morning at Sotheby's for $374,500. The auction house originally estimated the item would sell for $120,000 to $180,000.
Filed under "Fine Books and Manuscripts," the motherboard is operational and is marked "Apple Computer 1" and dated 1976. "It is thought that fewer than 50 Apple 1 Computers survive, with only [six] known to be in working condition," Sotheby's reports in catalog notes.
The iconic piece of technology history features a MOS Technologies 6502 microprocessor and 8 kilobytes of RAM. The original Apple 1 computers retailed for $666.66 in 1979 and did not include a monitor, keyboard, case or power supply. Only about 200 Apple 1 computers were produced.
