Abstract
Abstract A method and apparatus for displaying information on the screen of a monitor which permits the simultaneous display of a first character and a second character in a single raster location on the screen of a monitor, and hence the overstriking or modifying of a first character with a second character in a single raster location on the monitor. In one form of the invention which involves a field sequential operation, a character generator will permit the alternate display of information from two separate memories in a single raster location by super-imposition of the characters in the raster location on the monitor. In another form of the present invention, involving line-sequential operation, a pair of character generators are employed and each operate in conjunction with each of a pair of memories and the characters thus generated in each character generator is combined in a mixer and displayed in the superimposed fashion on the screen of a monitor.
