Integrated Circuit Computers

Research and development of integrated circuit computers started in 1965, with production starting in the early seventies. All of the early models used small-scale ICs and magnetic core memory.

Two pilot models using ICs made in China were completed in 1971. The model 111 was developed by the Institute of Computing Technology of Academic Sinica. It was a general purpose computer with a 48-bit word length and a set of 62 instructions, and was configured with a 32K word magnetic core memory. Average speed reached 300,000 instructions per second.

The DJS100 Series United Design Group was set up in June 1973, and comprised Tsinghua University, Beijing number 3 Computer Factory, Tianjin Institute of Radio Technology and other organisations. Tsinghua University led the project.

There were more than 14 models in the DJS100 Series. The design of the first model, DJS130, was completed in January 1974, and the prototype completed and appraised in the following August. Details of 14 of the DJS100 series models are as follows:

DJS130 was the basic model. Its design followed that of the Data General Nova 1200, and it was built using small-scale ICs. DJS131 was similar, but used a different type of IC. Both were very successful. 

Both smaller and larger models were developed based on the DJS130/131. The design of the DJS140 followed that of the Nova 840, which had dedicated floating point and multiply-divide functional units. Most of the DJS100 models still used magnetic core memory, but those developed in the early eighties began to use MOS memory.

注：
1. 还有更多内容，限于篇幅我就不全部摘录了。这些记录相当全面准确，比我在国内网站看到的一些帖子写出来的要详尽。有兴趣的朋友请自己去查看。
2. 但同时这些记录也有一个小错。本人用过DJS130，本人的老师里有一些参加了这些计算机的研制。DJS130是48位机。这份资料里说成是16位的。DJS100系列是基于111型机发展起来的。111型机是48位。所以DJS100系列应该都是48位。至少我可以肯定地说DJS130是48位。
3. 还有就是速度。按这份资料，111型机速度是每秒30万指令，但没提DJS100系列的速度。我的记忆里，DJS130的速度是130万，DJS110的速度是110万，DJS140的速度是140万。
4. 尚有其他科学杂志文章提及中国毛泽东时代计算机发展情况。以下为一例：
