Abstract
A method and apparatus for generating, under the control of a microprocessor, signals for operating a visual display mechanism of the scanning type. The position of the scan is tracked, and when it approaches a desired location on the display area for a particular segment to be displayed, it responds thereto by directing delivery to the scanning system of control signals which define the selected display segment. A plurality of display segments, each containing information at least partially defining one or more object images which it may be desired to be included in a specified display, are stored in a cartridge memory which can also include specific operating instructions for carrying out a particular game or other function with such display segments. Each of the display composers includes an associative memory arrangement for addressing the cartridge memory and directing feedout therefrom of specified segments at times required during the scan. A FIFO buffer is also included in each of the display composers for delivering information defining an object image at a regular rate correlated to the scanning rate, irrespective of the time in which such information is made ready for the display.
