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.

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
