摘    要：本文介绍微型计算机连接纸带输入机的总线接口.重点叙述了从微型机输入/输出信号及外设的外特性出发,在综合考虑信息交换方式的基础上,确定接口硬件的设计思想.对具有特殊要求的气象数据纸带管理软件的开发,作了较为详细的论述.在 TRS-80机上进行了具体方案的实施,取得了令人满意的结果.

Abstract: An interface connecting a PTR to microcomputer is described in the present Paper.Analyzing input/output of microcomputers and outer features of the auxiliary devices,considering various information exchange means,the auther determined the design of the hardware.Also,detailed deseription is given to the administration software developed for the paper tape used for weather data.The PTR intertace was designed to be used on TRS-80 microcomputer,and the trial on it gave a satisfactory result.
