Distributed data processing system

摘要

A distributed data processing system having a magnetic disk and a master disk control and communication control unit; a slave work station unit having a keyboard for the input of data and a cathode ray tube display screen for the display of input data; and a slave output printer. The work station display is a CRT screen which can display 24 lines each of 80 characters, or a total of 1920 characters. The keyboard is similar to that of a standard electric typewriter with the addition of special instruction keys and keys for moving a cursor symbol on the screen. Optionally, other slave peripheral devices, such as a telecommunications link, a line printer, or a paper tape punch, may be provided. All slave units of the system are connected to the master unit by coaxial cables.
