PC系列微机可读写电子磁盘的设计与实现

Design and Implementation of Readable/Writable Electronic Diskette in PC-Series Computers

介绍了一种多功能可读写电子仿真磁盘，它不仅可以完全替代传统磁盘及驱动器，而且还可以用来固化用户的应用程序．它仍可利用丰富、灵活、功能强大的磁盘操作系统软件，对用户来说如同操作传统软磁盘一样，而其读写速度、可靠性、结构安装及性能价格比都是传统的磁盘所不能比拟的．它具有３６０ｋＢＲＯＭ和２５６ｋＢ带掉电保护静态ＲＡＭ，实际所占内存空间仅４ｋＢ．它特别适用于环境恶劣并要求高可靠性、高存取速度的工业现场实时自动检测及控制方面存储用户程序和数据的应用．

A multifunction readable/writable electronic diskette was developed not only to substitute entirely the traditional ones and drivers but to fix user's application programs. Taking advantages of the plentiful,flexible and powerful DOS softwares,the multifunction diskette provides not only the traditional performance,but incomparable improvements of reading and writing speeds,reliability,structure and cost performance. It has a 360 kB ROM and 256 kB static RAM for power-off protection,with only 4 kB memory locations taken up. It is applicable for saving user's programs and data,especially,in case the high reliability and high access speed are required for automatic real-time measurements and controls under severe working conditions.
