On this day, 39 years ago, on May 21, 1986 (April 13, 1986, the lunar calendar), my country's electronic computer advanced display processing system passed the appraisal. On May 21, 1986, the electronic computer advanced display processing system passed the appraisal. This is another major scientific and technological achievement achieved by my country in the field of electronic computers after the "Galaxy" billion-time computer. This advanced display processing system can be widely used in real-time control of production processes, computer-aided design, and processing of meteorological, geological, mineral deposits, remote sensing, and telemetry images. He can quickly display six directions of graphics and four directions of text with different contents at the same time. He is equipped with a fully functional plane and three-dimensional drawing system and Chinese and Western language processing system. He can use 16 million colors to form various realistic three-dimensional color images. It is currently the largest and most powerful computer advanced display processing system in China, and its performance exceeds the level of similar products currently introduced in China. This advanced display processing system was successfully developed in collaboration with the National University of Defense Technology and relevant research institutes, colleges, factories and other units.
