The Speedboard is, well, a plastic board where you put the NES controller on while you play. That's it. It's advertisement says: "The Speedboard, the fastest way to play your Nintendo Entertainment System! Puts the speed at your fingertips! Increase your game scores! Better reaction time and speed! Holds your controller so you don't have to!" It was designed so that you could put the controller down on your lap maybe or on the table so as to allow you to press the buttons rapidly. In short, it sucked. You know of other Nintendo accessory fails?
