A text-editing system includes a central processor unit, a bus connected to the central processor unit and input terminals connected to the bus for entering text and editing commands into the system. Text is displayed by the system on visual display apparatuses that are associated with each input terminal based upon information that is stored in display memories. A multiplexer circuit connects plural visual display apparatuses to the bus and a display memory and routes address and data signals between the display memory and either the bus or selected ones of the visual display apparatuses.
