ABSTRACT:
A video display control system with a relative position memory between a controller and a foreground memory to permit changing the correspondence between a control indicator, indicating a display line on a monitor, and that one of the blocks of foreground memory controlling the foreground characters to be displayed on that display monitor screen line. The controller indicator signal is provided directly to a background memory to indicate which block of data therein is to control the display for the graphics background on that screen line. The relative position memory circuit also sets the first column in a test line which is to display in an allocated portion of the monitor screen. The relative position memory and the foreground memory control a symbol memory, and the outputs from the foreground memory, the symbol memory and the background memory are collected by a display controller capable of operating a display monitor.
