SBC-80/10和SBC80/10A是Intel公司OEM计算机系统单板计算机的典型产品之一。它广泛地用于各种自动检测设备、过程控制设备中。如我国由美国E/C公司进口的印制板线路检验机,就是由SBC-80/10A单板计算机作为中央控制器的自动检测设备。本文较全面地介绍了SBC-80/10和SBC-80/10A单板计算机的系统组成、工作原理、信息传送过程及其定时关系;对RAM、ROM、可编程串行I/O通讯接口和并行I/O接口作了重点的说明;此外还介绍了SBC-80/10和SBC-80/10A如何通过多总线(Multi-Bus)与其它主机模件相连,组成微型计算机系统。本资料主要从硬件的角度介绍了微处理机的系统设计、安装和使用,但也涉及到了部分与硬件有关的软件知识。对用户自行设计微处理机系统具有显而易见的参考价值。我们在调试以SBC-80/10A为中心的线路检验机和使用微处理机的过程中,深感本资料是一份有关微处理机系统较完整的硬件参考资料。译文删除了附录C中8080指令系统部分。有关这部分的详细内容,读者可参阅76年第12期计算机参考资料“8080微型计算机系统用户手册”一文。为对8080微处理机用户编制程序提供方便,我们参照“A Step By Step Instruction TO 8080 MicroprocessorSystems”等书,并结合我们工作实践,编译了“8080指令的字母顺序排列表”和“8080指令的助忆符与操作码对照表”,加在附录C中。我们在使用微处理机过程中,深感此表编制科学,简明扼要,尤其对初学者来说,是编制程序时必不可少的有用资料。由于时间和译者水平有限,译文不免有一定的错误和缺点,望读者批评指正。
The SBC-80/10 and SBC80 / 10A are typical of Intel Corporation OEM computer system single-board computers. It is widely used in a variety of automatic testing equipment, process control equipment. Such as China by the United States E / C company imports printed circuit board testing machine, is the SBC-80 / 10A single-board computer as the central controller of the automatic detection equipment. This paper introduces the system composition, working principle, information transfer process and timing relationship of SBC-80/10 and SBC-80 / 10A single board computer in a comprehensive way. It introduces the RAM, ROM, programmable serial I / O communication interface and Parallel I / O interface. In addition, it shows how SBC-80/10 and SBC-80 / 10A can be connected to other host modules through Multi-Bus to form a microcomputer system. This information mainly introduces the microprocessor system design, installation and use from the perspective of hardware, but also involves some hardware-related software knowledge. The user-designed microprocessor system has obvious reference value. We are in the commissioning of the SBC-80 / 10A-centric line inspection machine and the use of microprocessors in the process, the depth of this information is a more complete reference about the microprocessor system hardware. The translation deletes the 8080 Command System section of Appendix C. For details of this section, readers can refer to the article entitled “User’s Manual of 8080 Microcomputer System”, Computer Reference No. 76, In order to facilitate the 8080 microprocessor user program, we refer to “A Step By Step Instruction TO 8080 MicroprocessorSystems” and other books, and combined with our work practice, compiled the “8080 instruction alphabetical list” and “8080 instruction help Yi Fu and opcode comparison table ”, added in Appendix C. We are deeply involved in the use of microprocessors in the preparation of this science, concise, especially for beginners, it is essential for the preparation of procedures useful information. Due to the limited time and translators, the translation can not help but have certain mistakes and shortcomings, hope readers criticize and correct.
