<p>PURPOSE:To attain the input and output for each electronic computer as if it were an exclusive display device by providing an exclusive memory at a memory part of a display device and a changeover switch at a display part and displaying selectively the display data supplied from plural electronic computers. CONSTITUTION:When an input/output request is fed to a display device 4', an electronic computer 1 or 2 supplies the input/output to a control part 5 via a multiplexer 3. Then the display data are stored to exclusive memories 61 and 62 corresponding to computers 1 and 2 set above a memory part 6. The memories 61 and 62 are connected to a display 7 via a changeover switch 9, and the stored display data are displayed on the display 7 by switching the switch 9. In such a way, the complicated control processing between both computers A and B is omitted, therefore both the reliability and processing performance are improved.</p> |
