引言 DG0040系列四位微型机电路是在合肥晶体管厂,邵阳无线电厂,88101部队研制的基础上,由邵阳无线电厂,88101部队,北京878厂重新进行逻辑设计,由北京878厂负责版图设计,工艺试制和生产。在上级机关的领导下,三家亲密协作,用了一年的时间完成了设计、试制、样机装配等工作,现在已由北京878厂批量生产。国产四位机已在专业计算,智能仪器仪表,工业控制等方面获得了广泛的应用。由于 Introduction DG0040 series of four-bit microcomputer circuit is based on the Hefei transistor factory, Shaoyang radio factory, 88101 units developed by the Shaoyang radio factory, 88101 units, Beijing 878 factory logic design, by the Beijing 878 plant is responsible for layout design, technology Trial production and production. Under the leadership of the higher authorities, the three close collaboration took a year to complete the design, trial production, prototype assembly work, and now has been mass-produced by the Beijing 878 factory. Domestic four-bit machine has been in a wide range of applications in professional computing, intelligent instrumentation, industrial control and so on. due to
