Biography

Joe Decuir is an American engineer whose work connects several important generations of Atari and Amiga hardware. He joined Atari in the mid-1970s and became one of the engineers who turned the company's arcade experience into practical home systems.

Decuir helped design the Atari Video Computer System, later renamed the Atari 2600, including work on its hardware and early game code. He then worked with Jay Miner and the team that created the Atari 400 and 800 computers. His most enduring contributions to those machines included the Serial Input/Output system, which let computers and peripherals communicate through a simple daisy-chained cable.
Decuir later joined the Amiga project and contributed to the custom-chip architecture behind the Amiga 1000. Across these projects, his work helped make sophisticated graphics, sound and peripheral control available in affordable consumer machines.
