5′ (3 meter) Atari SIO Cable

Description

Custom-made 5′ (3 meters) long Atari SIO cable. High-quality, injection-molded SIO connections with 12 (all but the motor control line) conductors wired.

The Serial Input/Output system, universally known as SIO, was a proprietary peripheral bus and related software protocol stacks used on the Atari 8-bit family to provide most input/output duties for those computers. Unlike most I/O systems of the era, such as RS-232, SIO included a lightweight protocol that allowed multiple devices to be attached to a single daisy-chained port that supported dozens of devices.
