一般地说,APPLEⅡ微电脑系统的检修与其它任何电子仪器仪表的常规检修一样,首先要熟悉它的工作原理,参看它的方框图和线路图,对它有一个基本的清晰的了解,这是进行检修的基础和出发点.然后用各种检测手段,包括常规检测手段如万用表、示波器以及专用检测手段(如故障寻迹器、逻辑分析器等),经过边测试,边分析,找出引起故障的真实原因,再进行维修,排除故障,从而使系统正常运行.但是,微电脑系统的检修还存在特殊的困难,一是微电脑品种规格型号五花八门,而微电脑系统的测试方法没有通用性,适用于这类微电脑的.不一定适用于另一类微电脑,因此给检修带来困难;二是微电脑系统
Generally speaking, APPLEⅡ microcomputer system maintenance and any other electronic instruments routine maintenance, we must first familiar with its working principle, see its block diagram and wiring diagram, it has a basic clear understanding of this is the overhaul And then use a variety of detection methods, including conventional detection methods such as multimeter, oscilloscope and special detection methods (such as fault tracing, logic analyzer, etc.), through the side of the test, while analysis to find the cause of the malfunction Reasons, and then repair, troubleshooting, so that the normal operation of the system.However, the maintenance of the micro-computer system there are still special difficulties, First, the variety of micro-computer models vary, while the microcomputer system testing methods are not universal, suitable for such micro-computer . Not necessarily applicable to another type of micro-computer, so to repair difficulties; second micro-computer system
