据不完全统计,我国各有关部门先后从美国Cromemco公司引进了约2000套微型计算机系统。这些系统,特别是CS—3系统大多数都配置了PerSci公司制造的299B型双软磁盘驱动器。根据有关单位的使用情况表明,299B是该系统中故障率最高的一种外部设备。一旦它发生故障,整个微型机系统的工作就会陷于瘫痪。因此,正确使用和维护好软磁盘驱动器,对于保证微型机系统的正常运行是十分重要的。
According to incomplete statistics, all relevant departments in China have successively introduced about 2,000 microcomputer systems from the United States Cromemco Company. Most of these systems, especially the CS-3 systems, are configured with PerSpy’s Model 299B dual-disk drive. According to the use of the relevant units show that 299B is the highest failure rate in the system of an external device. Once it fails, the entire micro-computer system will be paralyzed. Therefore, the correct use and maintenance of the floppy disk drive, to ensure the normal operation of the microcomputer system is very important.
