M—340计算机中的服务工作站处理机(简称SWP)在整个系统中有很强的功能,它不仅作为一个独立的子系统而有自己的CPU、内存、外设接口和软磁盘驱动器等设备,而且作为M—340机的工作站,实现系统与外界管理界面的对话。SWP最多可接16台CRT终端,可任意指定某台终端为主控制台,其他终端提供给用户或指定为副控制台。各种操作员命令或系统信息都通过它输入或输出,控制M—340系统的运行和调度。因而,SWP是个关键的设备,了解它的内部结构和功能,可使我们进一步掌握使用M—340机系统的主动权,更好地发挥机器效率。
The Service Station Handler (or SWP) in the M-340 computer has strong capabilities throughout the system, not only as a stand-alone subsystem but with its own CPU, memory, peripheral interfaces, and floppy disk drives and more As M-340 machine workstations, to achieve the system and external management interface dialogue. SWP can connect up to 16 CRT terminals, any terminal can be designated as the main console, other terminals provided to the user or designated as the deputy console. Various operator commands or system information are input or output through it to control the operation and scheduling of the M-340 system. Therefore, SWP is a key device. Understanding its internal structure and function enables us to further understand the initiative of using the M-340 system and make better use of the machine efficiency.
