以大规模集成电路为基础的微型计算机的出现,是七十年代科学技术发展重大成果之一。它的出现不仅使计算技术进入崭新的阶段,而且使科学技术各个领域引起重大变革。从它诞生以来短短五、六年间,已使计算技术迅速普及并深入到国民经济各个领域,许多应用的成果已显示出微型计算机具有强大的生命力。我国的微型计算机事业还比较年轻,它的研制工作是从1974年开始的。在四机部直接领导下,有关单位联合设计,已经研制出以P The emergence of microcomputers based on large-scale integrated circuits is one of the major achievements in the development of science and technology in the 1970s. Its emergence not only brought computing technology to a completely new stage, but also brought about major changes in all fields of science and technology. In a matter of five or six years since its inception, computing technology has been rapidly popularized and deepened into all fields of the national economy. The achievements of many applications have shown that microcomputers have a strong vitality. China’s micro-computer business is still relatively young, its development work began from 1974. Under the direct leadership of the four-machine department, the joint design of the relevant units have been developed to P
