DJS-140是100系列高档机,它于1979年5月研制成功。国家计算机总局在同年8月主持了DJS-140机的考核、鉴定,结果认为:该机硬件、软件系统配套,功能齐全,稳定性良好。已经在北京计算机三厂,锦州无线电二厂,辽源无线电三厂等工厂投产。在国内小型机中,DJS-140机首先成功地配备了内存管理保护部件,64位双精度快速浮点部件,内存容量可扩充到256KB,配置了磁盘,磁带等相当齐全的外部设备。尤其是完整的装配了磁盘操作系统和各种语言程序以及服务程序。可以说DJS-140机不论硬件还是软件都居国内先进水平。DJS-140机是小型通用的计算机系统,可用于科学计算、数据处理和实时控制。将来还可以发展成双机、多机系统,以适应更高、更大的任务的需要。为了使广大读者和用户了解DJS-140机的性能和特点,以便很好的推广应用。本刊将陆续发表以下几篇文章,对该机进行较系统的介绍。(1) DJS-140机总体概貌(2) DJS-140机的处理机——CPU、FPU、MMPU (3) DJS-140机的磁芯存贮器(4) DJS-140机外部设备介绍(5) DJS-140机的系统软件DJS-140计算机是DJS-130机的发展和提高,而DJS-130机已为国内大多数同行所熟知。因此,以上各篇重点是介绍与DJS-130机不同和先进的部分。
DJS-140 is a 100 series of high-end machine, which was developed in May 1979. In August of the same year, the State Computer Administration presided over the examination and appraisal of DJS-140, and concluded that the hardware and software system of this machine are complete and fully functional with good stability. It has been put into operation at Beijing No. 3 Computer Factory, Jinzhou No. 2 Radio Factory and Liaoyuan No. 3 Radio Factory. In the domestic minicomputers, DJS-140 machine first successfully equipped with memory management protection components, 64-bit double-precision fast floating-point components, memory capacity can be expanded to 256KB, equipped with a disk, tape and other external devices quite complete. In particular, a complete assembly of the disk operating system and various language programs and service programs. It can be said DJS-140 machine regardless of the hardware or software are living in the domestic advanced level. The DJS-140 is a small, versatile computer system for scientific computing, data processing and real-time control. The future can also be developed into dual-machine, multi-machine system to meet the needs of higher and larger tasks. In order to make readers and users understand DJS-140 machine’s performance and features, in order to promote a good application. The publication will be published in the following articles, a more systematic introduction to the aircraft. (1) Overview of DJS-140 Machine (2) Processor of DJS-140 Machine - CPU, FPU, MMPU (3) Magnetic Core Storage of DJS-140 Machine (4) DJS- 5) DJS-140 machine system software DJS-140 computer is the DJS-130 machine development and improvement, and DJS-130 machine has been well known to most domestic counterparts. Therefore, each of the above articles focuses on introducing different and advanced parts to the DJS-130.
