国产DJS-051A微型计算机系统是以小型光电机(或电报头)和小型行式打印机作为其基本输入、输出装置。另外还配有CRT、TTY、盒式磁带机以及模拟-数字和数字-模拟转换器等。作为其基本输出装置的是CYD-1型打印机,尽管它的位数不够多而且字符种类也较少,但目前国内市场上,无论是在功能方面还是在价格方面,都还没有和微型计算机相称的且比它更好的产品。之所以把它作为基本输出装置,是因为它具有体积小、重量轻、价格便宜等优点,而且能够满足一般用户的要求。 本文主要介绍CYD-1型打印机如何与国产DJS-051A微型计算机系统相接口,着重叙述接口电路的主要功能及其在国产DJS-051A微型计算机系统中的应用。
Domestic DJS-051A micro-computer system is a small photoelectric (or telegraph) and small line printer as its basic input and output devices. Also comes with CRT, TTY, cassette tape drives and analog - digital and digital - analog converters. As its basic output device is a CYD-1 printer, although it’s not enough digits and fewer types of characters, but the current domestic market, both in terms of function and price, have not commensurate with the microcomputer And better products than it. The reason why it is used as a basic output device, because it has the advantages of small size, light weight, low price, but also to meet the general user requirements. This article mainly introduces how the CYD-1 printer interface with the domestic DJS-051A microcomputer system, mainly describes the main functions of the interface circuit and its application in the domestic DJS-051A microcomputer system.
