国外Z—80微型计算机系统已普遍使用。但Z—80微型计算机种类繁多,从几片大规模集成电路组成的最小系统和单板计算机直至功能较强的(具有高级语言及操作系统)微型计算机系统。本文介绍的Z—80系统是8位微型计算机系统中功能最强的型号之一,并相继地叙述了该系统的S—100总线、中央控制部件、存贮部件、I/O接口部件和磁盘控制部件。最后还扼要地叙述了本系统的驻留操作系统。通过本文的介绍,使读者不仅对此系统的结构有简要地了解,而且对了解其它型号微型计算机系统结构也具有一定的引导作用。
Foreign Z-80 microcomputer system has been widely used. However, the Z-80 is a wide range of microcomputers, ranging from the smallest system and single-board computers in large scale integrated circuits to the more powerful microcomputer systems with high-level languages and operating systems. The Z-80 system described in this article is one of the most powerful 8-bit microcomputer systems and describes the system’s S-100 bus, central control unit, storage unit, I / O interface unit, and disk Control unit. Finally, a brief description of the system resident operating system. Through the introduction of this article, readers not only have a brief understanding of the structure of this system, but also have some guidance on understanding the structure of other types of microcomputer systems.
