Game Console Controller- Dismantled for reference and curiosity
While the rest of the world received the larger XBOX Controller "Fatty" or "Duke" bundled with the original XBOX, the "Controller S" also known as the "Akebono" was distributed in Japan instead.
Due to arguably fair criticism of the Fatty controller's design, by 2002 it had been replaced as the pack-in controller for the US and then in Europe the following year. The Fatty could still be purchased as a separate accessory.
Both the Fatty and Controller S offer two analogue thumb sticks, a directional pad (pressure sensitive), two analogue triggers, six 8-bit analogue action buttons, Start and Back buttons, two vibration motors and two accessory ports.
An often overlooked innovation is the controller / console and probably life saving 'breakaway' cable that separates just past where it connect to the XBOX. Should you trip over the cable they snap apart saving you, the bowl of chips you're carrying while not pulling your system onto the floor. The cables aren't damaged in the process and snap back into place.
The controller connects to the XBOX using a proprietary USB interface, however with a little jiggery pokery and 3rd party drivers they will work on a standard PC as a USB controller.
The two accessory ports found to the rear of the controller accept eight megabyte memory cards to which save game data can be stored either in-game or from the XBOX dashboard memory manager utility. This allows most save game data to be moved from one XBOX to another; some games prevent this feature.
The XBOX controllers are not natively compatible with the XBOX 360 or XBOX One and probably any futher systems.
