Abstract: A readout means provides encoded information representing each character to be written on a cathode-ray tube screen as well as five enhancement levels. The output of the readout means is decoded into a video format and fed through a selectively actuated inverter for control of the cathode-ray beam. In response to signals at one of two of the memory enhancement output levels, the intensity of the displayed character is uniformly reduced or caused to pulsate. In response to an underline signal at one of the enhancement levels coinciding with a selected scan line, the inverter is actuated writing a row of dots under a desired character. A cursor signal at one of the enhancement levels actuates the inverter producing a cursor indication upon the screen and a tabulate enhancement signal creates a tabulate mark upon the screen.

Abstract: A system for controlling the operation of a recirculating memory having a binary counter to indicate the address of data in the memory, including two storage stages in the recirculating path of the memory, with gating to deliver timing pulses to the two storage stages so as to cause them selectively to provide two, one, or zero elements of data storage in the recirculation of data in order to influence the phasing between the recirculating memory and the binary counter.
