CX10 joystick

The Atari CX40 joystick is the first widely used cross-platform game controller. The original CX10 was released with the Atari 2600 (originally the Atari Video Computer System) in 1977 and became the primary input device for most games on the platform. The CX10 was replaced after a year by the simpler and less expensive CX40. The addition of the Atari joystick port to other platforms cemented its popularity. It was the standard for the Atari 8-bit computers and was compatible with the VIC-20, Commodore 64, Commodore 128, MSX, and later the Atari ST and Amiga. Third-party adapters allowed it to be used on other systems, such as the Apple II, Commodore 16, TI-99/4A, and the ZX Spectrum.
