What is Atari CX40 joystick?
[[File:Atari-2600-Joystick.jpg|thumb|The Atari CX40 joystick with one button and an 8-directional stick]] The '''Atari CX40''' is a single-button [[joystick]]. It was the first widely used [[cross-platform]] [[game controller]]. The original '''CX10''' was released with the [[Atari 2600|Atari Video Computer System]] (later renamed the Atari 2600) in 1977 and became the primary input device for most games on the platform. The CX10 was replaced after a year by a simpler and less expensive CX40. The addition of the [[Atari joystick port]] to other platforms helped it retain its popularity. It was the standard for the [[Atari 8-bit family]] of home computers and was compatible with the [[Commodore VIC-20|VIC-20]], [[Commodore 64]] and [[Commodore 128|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]] and the [[ZX Spectrum]]. ==Further reading== ===Bibliography=== * {{cite patent |country = US |number = 4124787 |status = expired |title = Joystick controller mechanism operating one or plural switches sequentially or simultaneously |pubdate = 1978-11-07 |gdate = 1978-11-07 |fdate = 1977-03-11 |pridate = 1977-03-11 |inventor = |invent1 = Gerald R.
