About This Item
961-1987 is a technical standard for the Bit Microcomputer Bus System, commonly known as the STD Bus, within the computing and processing field. It addresses the bus architecture used to connect microcomputer boards and related components, helping define how modules can communicate and operate together. For engineers, integrators, and procurement teams working with legacy embedded systems, 961-1987 provides a useful reference for compatibility, design consistency, and system-level planning.
About 961-1987
This standard focuses on the STD Bus, a compact microcomputer bus system used to link processing, input/output, and support boards in modular hardware designs. 961-1987 is relevant where a defined electrical and mechanical interface is needed to keep components interoperable across a system. In practice, it may guide how boards are arranged, connected, and evaluated within a microcomputer platform. Its value lies in establishing a common technical framework for consistent implementation.
Where is 961-1987 used?
961-1987 is most relevant in modular computing equipment and embedded control systems that rely on the STD Bus architecture. It may be used in industrial controllers, laboratory instruments, instrumentation platforms, or other systems built around card-based microcomputer hardware. In these environments, the standard helps align board design and system integration so that modules can function together predictably. It is especially useful when maintaining, sourcing, or documenting legacy systems built around the STD Bus.
Importance in practice
In practice, 961-1987 helps reduce uncertainty when designing or supporting hardware that uses the STD Bus. A clear standard can improve compatibility between boards, support more reliable testing, and simplify procurement of replacement or complementary modules. It also helps organizations maintain consistency across equipment builds and upgrades, which can lower integration risk. For inactive standards, it remains important as a technical reference for existing installations and long-lived systems that still depend on the original bus structure.
