利用现有微机系统和单板计算机,实现微型机与单板机间的直接双向通讯,是一件极其有意义的工作。系统的互连结构应尽可能简单,在不影响微机和单板机原设计功能的基础上,尽量不改动或少改动原机硬件结构,以适应微型机和单板机体积小,成本低的特点。本文介绍的方法是将 Cromemco-Ⅲ微型机与 Z80单板机构成互为外设来连接进行数据传输的。系统的构成无需增加或改动硬件,只需一根电缆将两机互连。
The use of existing computer systems and single-board computer to achieve direct two-way communication between the microcomputer and single-board machine, is an extremely meaningful work. System interconnection structure should be as simple as possible, without affecting the original design functions of the microcomputer and the single-board machine, based on the original hardware as little or no changes to the hardware structure to adapt to small machines and single-board machines, small size, low cost Features. This article describes the method is the Cromemco-Ⅲ microcomputer and Z80 single-board mechanism as a peripheral to connect for data transmission. System configuration without adding or changing hardware, just a cable to two machines interconnection.
