显示终端和针印机是使用面广、量大的两种计算机外部设备,特别是在MC68000微型计算机系统中,由于它是多用户系统,每个用户依靠显示终端作为输入设备(当然也可作为输出设备),针印机作为硬拷贝,如果不能及时维修显示终端和针印机的故障,必然会影响用户的工作。而两种设备之间的联接故障是最常见的,故障原因多种多样。本文针对950型显示终端和8510型针印机,介绍它们之间联接故障的检查、定位与维修技术。其基本思想对于其它类型的显示终端和针印机也同样适用。
Display terminals and stampers are two types of computer peripheral devices that are widely used and large in size. Especially in the MC68000 microcomputer system, each user relies on a display terminal as an input device because of its multi-user system (of course, Output device), pin printer as a hard copy, if you can not promptly repair the display terminal and pin printer failure, will inevitably affect the user’s work. The connection between the two devices is the most common failure, a variety of reasons for failure. This article is aimed at the 950 display terminal and the 8510-type pin printer, describes the connection between them fault inspection, positioning and maintenance techniques. The basic idea also applies to other types of display terminals and stampers.
