在电子显像管的生产和科研领域中,随着计算机辅助设计的日趋普及,人们对计算机的容量、速度及精度等项要求也越来越高。CAD 工作者的目光开始转向各种各样的386、486甚至小型机上。但对于那些开展微机CAD 较早的工厂或研究所来说,原先已在使用的一些 PC/XT 机,AT 机应该如何处置是一个不得不考虑的问题。因为新机器的运算速度往往是老机器的十几倍甚至几十倍,工作人员不再喜欢用老机器,这就在一定程度上造成了设备的闲置。 In the field of production and scientific research of electronic picture tubes, with the increasing popularity of computer-aided design, people are increasingly demanding such items as computer capacity, speed, and accuracy. The eyes of CAD workers began to turn to a variety of 386, 486 or even minicomputers. However, for those factories or research institutes that have conducted microcomputer-based CAD earlier, some of the PC/XT machines that were already in use, and how the AT machines should be disposed of, are issues that have to be considered. Because the operating speed of new machines is often ten or even dozens of times that of old machines, the staff no longer likes to use old machines, which causes the idleness of the equipment to some extent.
