当展望八十年代的小型计算机时,回顾一下七十年代小型计算机的发展也是很有意义的。六十年代前期开始研制主要用于控制而价格较低的小型计算机,可以说直到七十年代,它的硬件、软件性能和应用领域才有了较大的提高和发展。 被IBM和七家小公司所占领的主机市场中有几家小公司从中分了出来,而以DEC为首的小型计算机制造厂在这十年中发展得很快。 从技术上看,七十年代小型计算机的结构特点是,字长为16位。各个公司都以字长为16位的信息处理机为基础,对外部设备和
When looking at small computers in the 1980s, it is also worth recalling the development of small computers in the 1970s. Since the early 1960s, the development of small-sized computers mainly for control and lower prices can be said that it was not until the 1970s that its hardware, software performance and application fields had greatly improved and developed. Several small companies in the mainframe market, which was occupied by IBM and seven small companies, were divided and the small-computer factory led by DEC grew rapidly in the decade. From a technical point of view, the structure of a small computer in the 1970s was characterized by a word length of 16 bits. Each company is based on an information processor with a word length of 16 bits, and external devices
