The Atari Serial Input/Output System or SIO was designed to allow the computer to communicate with peripherals such as the 810 or 1050 disk drive. An advantage of the SIO is that multiple devices could be chained together. A major design consideration was allowing the computer to communicate with peripherals without the need for installing an internal card.

Unfortunately, a number of devices such as third-party printers used a different port called the RS-232. Atari made the 850 Interface Module to allow communication with devices that used the RS-232 port.
