引言近几年来,TP801单板计算机作为智能部件,已广泛用于生产控制过程、各种仪器和仪表或机械的单机控制、数据处理等等。而近年来,这种单板机还作为一种经济实用的实验数学设备,大量用于大专院校学生和其它初学者学习微型计算机的原理、组成、指令系统及编写程序的方法和技巧。但随着TP801单板机的广泛应用和普及,广大用户越来越多地遇到单板机发生故障急待维修的问题。由于单板机上的大部分部件是CMOS集成电路,它们的使用
Introduction In recent years, TP801 single board computer as an intelligent component, has been widely used in the production control process, a variety of instruments and meters or machinery stand-alone control, data processing and so on. In recent years, however, this single-board computer has also been used as an economical and practical experimental mathematic device, and has been used in a large number of methods, techniques, and procedures for the study of microcomputers by college students and other beginners. However, with the widespread use and popularization of the TP801 single-board computer, the majority of users are encountering the problem that the single-board computer is in an emergency and needs to be repaired more and more. Since most of the components on a single-board computer are CMOS integrated circuits, they are used
