Hobbyists who collect old computers for fun might want to add this Apple prototype to their collection. Dubbed the eMate 300, for those that remember, the device was shipped with a solid dark green casing as opposed to the clear casing pictured above. According to seller, about six of these see-through eMates were ever produced, making this one heck of a rare find. Originally designed as a low-cost device for the education market, it looks like it is still able to startup although we’re not sure just how much use you will be able to get out of it. It also appears to have inspired the design of the clamshell iBook laptops released back in the 90s. Either way the seller is currently listing this particular eMate 300 for a whopping price of $8,499.99 which could easily net you several 17” MacBook Pros or 27” iMacs, but hey, all in the name of history, right? For additional photos or information about the device, or possibly to place your bid, head on down to its eBay listing for all the details.
