Seen on eBay, Newton prototypes. We often see the transparent model, but not the other two. Two models offer an expansion card that seems to fit a PC Card slot, the last one is connected to a red NuBus card (typically used on prototypes).
At the time of writing, they are at €300 but the reserve price (minimum price expected by the seller) has not been reached.
