国产的HD1500型针式宽行汉字打印机现已作为我厂DIETZ621计算机系统中的汉字输出设备。从1980年9月开始,经过三个来月的努力,我厂已初步建立起一个高级语言BASEX语言的计算机汉字处理系统。本文主要从硬件角度介绍该打印机的性能、原理与DIETZ621计算机的接口;着重叙述接口电路的主要功能和设计思想,以便在汉字处理系统的发展中得到更深入的探讨。
Domestic HD1500 needle-type wide-format printer is now our country DIETZ621 computer system in Chinese characters output device. Starting from September 1980, after three months of efforts, our factory has initially established a computerized Chinese character processing system based on the BASEX language of high-level languages. This paper describes the performance of the printer, the principle and DIETZ621 computer interface from hardware point of view; focuses on the description of the main functions of interface circuits and design ideas in order to get more in-depth discussion of the development of Chinese character processing system.
