Abstract
Abstract A system for the display of information on a cathode-ray tube or the like wherein the information comprises a plurality of lines of text comprising a number of characters and wherein each text line is formed by a plurality of scans. The system comprises a main memory for storing sets of bits wherein each set of bits represents a different one of all the characters to be displayed and an auxiliary memory for storing the sets of bits comprising the particular text line being formed on the screen of the cathode-ray tube. The auxiliary memory is operable to sequentially present each set of bits stored therein at its output during each scan comprising the particular text line. Decoding means responsive to the set of bits of the output of the auxiliary memory is provided to modulate the electron beam to form areas of the character represented by the set of bits during a particular scan.
