SYSTEM FOR DISPLAYING ALPHANUMERICAL MESSAGES HAVING STORED AND REAL TIME COMPONENTS A system for displaying alphanumeric messages has a display device with a row of character stations at each of which a character may be created for display in response to a set of signals applied to the character station. A memory device stores a plurality of message fragments and a real time means provides a plurality of real time message fragments respectively representing a corresponding plurality of real time conditions. A control circuit in response to certain input conditions selects one stored message fragment and one real time message fragment and converts them to sets of signals applied in one to one relationship to the character stations to cause the display of a meaningful complete message by the display device. The memory may also store some complete messages which are convertible by the control circuit, without any input from the real time means, into sets of signals which are applied in one to one relationship to the character stations of the display device to cause the display of a meaningful complete message.
