Abstract
A non-interlaced raster-type display includes interface circuitry for displaying character patterns indicative of data signals manipulated by a processor under the control of a manually-operable keyboard. The displayed character patterns are enhanced by half-shifting or delaying a raster line of display signals for a given character in order to improve the legibility of displayed alphanumeric character patterns. A blinking pointer or cursor is manually movable via keyboard control to the character spaces desired and the blinking cursor display is inhibited during movement thereof in order to maintain an invariant display of the cursor during repositioning.
