The original Microsoft SideWinder gamepad had a digital directional pad, six fire buttons, two trigger buttons, and a "Mode" and "Start" button. The original gameport version had a pass-through, so additional joypads or joysticks could be used without unplugging the SideWinder, and also allowed the connection of up to four SideWinder gamepads working simultaneously. Newer USB versions of the SideWinder gamepad have a round digital directional pad instead of the more traditional cross-shaped directional pad, and lack the mode button. The Microsoft SideWinder's button layout is very similar to that of the Sega Saturn controller, which was released over the same time period.
