Control Pad (Master System)
From Sega Retro
The SMS Control Pad (Product No. 3020) is the joypad which comes packaged with SMS systems. The joypad connects to the SMS via a DB-9 port, so it is also compatible with the Commodore 64 and partially compatible with the Sega Megadrive. Resembling the 1st generation NES pads, three versions exist:
- Three button/mini-joystick. Once the thumbpad button cap was removed, a small "thumbstick" could be inserted.
- Three button. The third button sits recessed in the center of the thumbpad. The button has no function during gameplay.
- Two button. The thumbpad button as been entirely removed. This version is most commonly associated with the SMS II when it was introduced.
