一位微电脑在工业控制方面是国产微电脑中的佼佼者最早的一位微电脑是在1977年由美国 Motorola 公司推出的,由于它的结构简单,制造容易、价格便宜以及使用方便,受到了各国工业界的重视。美国1981年一位微电脑的销售量达900万套。我国在1978年引进这种技术,主要电路在1980年仿制成功。目前,我国已能自己设计、制造以 MC14500为核心的一位电脑配套电路。一位微电脑是一种最简单的电脑。所谓一位,是指这种电脑每次只能加工一位数据或信息。具体来说是它的内部运算器、寄存器都只有一位,它与外界联 A microcomputer in the industrial control is the leader in the domestic microcomputer The earliest a microcomputer was introduced by the United States Motorola in 1977, because of its simple structure, easy to manufacture, cheap and easy to use, by the national industry The importance of. In 1981, a microcomputer in the United States sold 9 million sets. Our country introduced this kind of technology in 1978, the main circuit succeeded in imitation in 1980. At present, our country has been able to design and manufacture a computer supporting circuit with MC14500 as its core. A microcomputer is one of the simplest computers. The so-called one, refers to the computer can only process one data or information at a time. Specifically its internal computing unit, the register is only one, it is linked with the outside world
