ELECTRONIC DATA PROCESSING SYSTEM

A data storage and retrieval system capable of performing various arithmetic functions such as adding and subtracting and for enabling a printing of any of the information and/or functions which take place in the system. The system includes one or more console units which may be remote or proximate to and connected to a central electronics unit through a multiplexer. The central electronics unit contains a memory section in the form of a magnetic storage member for retaining the information introduced into the system. At least one of the console units is provided with a printer control for controlling the mode of operation of a printing mechanism and the printer control of this one console unit is connected to a printer drive circuit. In like manner, the multiplexer and the central electronics unit are connected to the printer drive circuit. The output of the printer drive circuit is connected to a printer interface circuit which, in turn, enable operative connection to the printing mechanism.
