这里公布的不是最近生产的新式微型计算机系统,而是一个第二代或者改进了的系统。微处理机的发展倾向是增加功能,改进对这些功能的控制。最初,许多特征是固定的,后来硬件是可变的,最后软件是可编程序的。这种倾向也同样适应于各种微处理机系统的其它器件上。 What is released here is not a newly developed microcomputer system, but a second generation or improved system. Microprocessors have tended to increase functionality and improve control over these functions. Initially, many features were fixed, then the hardware was mutable, and finally the software was programmable. This trend is equally applicable to other devices in various microprocessor systems.
