Estimating the term…
A video terminal system having a plurality of distinct output devices providing humanly perceivable, alphanumeric information is disclosed. The video terminal processes and transfers the binary representations of each alphanumeric character to a character generator. A dot matrix corresponding to the character is provided by the character generator and is time-multiplexed so as to be time-shared by each of the output devices without the requirement for specialized circuitry and with minimal time degradation. The distinct output devices may be video displays and hard copy printers which display alphanumeric characters for a complete line, the video display devices receiving each complete line of characters in a predetermined time period and the printer devices receiving a slice of each character for a line upon request.
In a video terminal system having at least two display devices, one of said display devices displaying data at a rate approximately two orders of magnitude faster than the other display device, said video terminal system having a microprocessor executing instructions controlling transfers in said system, the process of providing data to each of said display devices comprising the steps of:
