Remember the Mac 128K prototype with the 5.25-inch ‘Twiggy’ drive? Our own Adam Rosen showed you the prototype in detail several months ago, and a model has now surfaced on eBay. The cost to own this piece of Apple history? $100,000. What’s even more interesting about this item is the seller. Looks like Apple co-founder Steve Wozniak might be cleaning out his closet.
