本标准提供了将8位微处理器应用于低成本模块化总线方案的规范。该总线的信号通常直接来自处理器设备，并被缓冲但不重定时。该方案导致一些模块依赖于处理器设备。本标准正文提供了与设备无关的参数的核心规范。附录提供了各种处理器的设备相关参数。

This standard provides specifications for applying 8-bit microprocessors to a low-cost modular busing scheme. The signals for this bus are generally derived directly from the processor device and are buffered but not retimed. This scheme results in some modules being processor-device dependent. The body of this standard provides a core specification for the device-independent parameters. Appendixes provide device-dependent parameters for various processors.
