While Ebay has been host to a number of Apple prototypes and rare machines before, a truly remarkable offering has been uncovered -- with an equally remarkable price. A seller going by the name "wozniac" in tribute to the Apple co-founder has put a complete and operational Macintosh 128k prototype created in advance of the actual debut of the Mac in January, 1984. This model even includes a "Twiggy" floppy disk drive, a very unusual addition.
