作为微程序的例子,准备介绍IBM360/20的部分情况。该部计算机是1964年制造的。反映了当时电路元件的妆况,是一部谋求减少元件,降低成本及减少故障从而具有很多微程序级（最高12288步)的机器。因此,对于操作开关,凡是使用微程序可以行得通的地方,都彻底地采用了微程序。 作为系统结构,有CPU(中央处理机),（2.020）卡片读出穿孔机（2560)、行式印刷机等。存贮容量4096字。笔者在1973年8月在IBM公司学习CE技术,现在边进行维修,边进行更改微程序,以便使其具有模拟其他计算机的职能。
As an example of a microprogram, we are going to introduce some of the IBM 360/20 cases. The Department of Computer was manufactured in 1964. Reflecting the makeup of the circuit components at the time, the machine was designed to reduce components, reduce costs and reduce malfunctions with many micro-program levels (up to 12,288 steps). Therefore, for the operation of the switch, wherever the use of micro-program can work, have thoroughly adopted the micro-program. As a system structure, there are CPU (Central Processing Unit), (2.020) Card Read Perforating Machine (2560), Line Printing Machine and the like. Storage capacity of 4096 words. The author studied CE technology at IBM in August 1973 and now performs maintenance while making changes to the microprogram so that it functions as a simulator for other computers.
