POKEY (Pot Keyboard Integrated Circuit) is a digital I/O chip designed by Doug Neubauer at Atari, Inc. for the Atari 8-bit computers. It was first released with the Atari 400 and Atari 800 in 1979 and is included in all later models and the Atari 5200 console.
POKEY combines functions for reading paddle controllers (potentiometers) and computer keyboards as well as sound generation and a source for pseudorandom numbers. It produces four voices of distinctive square wave audio, either as clear tones or modified with distortion settings. Neubauer also developed the Atari 8-bit killer application Star Raiders which makes use of POKEY features.
