A prototype model of the original Macintosh 128K with a 5.25-inch Twiggy drive has surfaced on eBay, with a starting bid price of $99,995. Apple planned to use its proprietary Twiggy disk format in the Macintosh, but switched to a 3.5-inch floppy drive for the final production model due to reliability concerns. The model on eBay will power on, according to the seller, but won't boot without Mac software on a Twiggy disk (which any buyer is unlikely to have).

While nearly $100,000 sounds somewhat optimistic on the seller's part, there's no doubting the fact that a Twiggy drive-equipped Mac would be an incredibly rare collector's item, so how would anyone have gotten hold of one? CultofMac is positing that the seller may be none other than Apple's co-founder Steve Wozniak himself. We're not so sure, though — while "wozniac" certainly has an impressive collection of Apple memorabilia for sale, the misspelling of his name and the fact that he's in Canada would seem to put paid to that theory. Besides, between reinventing flash memory and dropping in on Google to pick up Android phones, we're not sure Woz'd have the time to monitor the bid.
