TRS—80是一种未配置备用接口的通用个人计算机,而MCS—052/10则是一台专为数据采集与工业过程控制而设计的微型计算机系统。连接两台微型计算机使之联机工作将会提高系统的使用特性。本文介绍了上述两类微型计算机的基本结构与特性,详细阐述了在TRS—80系统总线上扩充串行接口的硬件连接,以及按MCS—052/10机监控命令格式编制的联机操作程序。此外,还介绍了该系统的操作使用方法,并在附录中给出了以BASIC程序语言编写的程序单。
The TRS-80 is a general-purpose personal computer that is not equipped with a backup interface, while the MCS-052/10 is a microcomputer system designed for data acquisition and industrial process control. Connecting two microcomputers to work online will improve system usage. This paper introduces the basic structure and characteristics of the above two types of microcomputers, elaborates the hardware connection to expand the serial interface on the TRS-80 system bus and the on-line operation program compiled according to the MCS-052/10 machine monitoring command format. In addition, the operation and usage of the system is introduced, and the program list written in BASIC programming language is given in the appendix.
