IEEE 696-1983

This standard applies to interface systems for computer system components interconnected by way of a 100-line parallel backplane commonly known as the S-100 bus.It applies to microprocessor computer systems, or portions of them, where: (1) Data exchanged among the interconnected devices is digital (2) A maximum of 22 devices are interconnected (3) The total transmission path length among interconnected devices is less than or equal to 25 in (63.5 cm)(4) The maximum------ switching rate of any signal on the bus is less than or equal to 6 MHz



New IEEE Standard - Inactive-Withdrawn. This standard is intended: (1) To define a rational, general-purpose interface system for designers of new computer system components that will ensure their compatibility with present and future IEEE Std 696 computer systems. (2) To provide the microprocessor computer-system user with compatible device families which will communicate in an unambiguous way without modification, from which a modularly expandable computer system may be constructed. (3) To enable the interconnection of independently manufactured devices into a single system. (4) To specify terminology and definitions related to the system. (5) To define a system with the minimum number of restrictions on the performance characteristics of devices connected to the system. (6) To define a system that, of itself, is of relatively low cost, and allows the interconnection of low-cost devices. (7) To define a system that is easy to use.
