The device works as follows.

In the absence of input or output of information, the device operates in the display mode, carried out periodic display (mp {e on the CRT screen of the indicator 7 of the image recorded) in the memory block 2 of memory (records recorded in the memory block 3, alphanumeric information recorded in the RAM 17, the character generator 10 and the marker with the coordinates specified in the counter 2 and 28 of the coordinate reading unit 11 with a frequency determined by the square pulse generator 43 of the raster shaping unit B. The generator 43 continuously starts serially connected first The second counter 44, which forms the raster column address, and the second counter 43, which forms the raster row address, the column address code goes to the first ROM 46, from the output of which, after the number of the last raster row element, a lower case lasting pulse is generated, and the row address code goes the second ROM 47, from the output of which, after the last row number, a personnel quenching pulse is formed. The horizontal and personnel quenching impulses are shifted by element 48 OR and are fed to the start of the generator of frame-1 and personnel frequency of the television indicator 7, It forms a periodic raster scan of a CRT beam, the coordinates of which elements coincide with the addressing of the first counter 49 and the second counter 50. Simultaneously, from the output of the first and second counters 49 and 50, the coordinates of the raster elements arrive at the first input of the switch of the memory management unit 9, and the lower the extinguishing pulses from the output of the first ROM 46 are received at the second control input of the switch and switch addresses to the output of the memory control unit 9, during the forward movement of the CRT beam from the output of the unit, during the reverse path of the beam the regeneration mode of the memory (storage), from the block counter, which at this time through the AND element is cocked from the generator 43.

Thus, during the forward path of a CRT beam from the output of the irregular memory unit 2 memory, C1: :) chronus reads.

The initial coordinates of the marker are set when deactivating ER.M by recording them in the first and second counters 27 and 28. The operator has to control the movement of the marker on the screen, change the status of the first And second counter 27 and 28 by aligning in the right direction iara 31, while turning the ball 31 vertices. time is transmitted to the angle-code sensor 29, and horizontal is transmitted to the sensor 30 angle-code, From the sensor 29 output the angle-code clock pulses go to the counting input of the first counter 27, changing the coordinate value of the marker along the vertical, and from the output 30 angle-code At the input of the second counter 28, changing the value of the coordinates of the marker vertically. When the operator installs a marker on the ELU screen, the coordinates are entered in the computer to specify the image or its parts, remove their coordinates from the outputs of the first and second counters 27 and 28 ,

In addition, on the screen of the television indicator 1 7, the graphics recorded in the second memory block 3 can be displayed, which is superimposed on the main image recorded in the first memory block 2. To display the graphics, with the appropriate command from the computer, from block 1 of the input registers to the second element I 1 .S a control signal is received that permits the passage of the graphic information read out synchronously with the movement of the CRT beam of graphic information from the second block 3 of memory 13 enters the DAC 4, to control the CRT modulator,

The on-line processing of the image output from the computer rendered on the screen of the television indicator 7 is carried out by setting the parameters in the register 42 of block 4 with the subsequent filling of the first and second RAM 39 and 41 to change the color or half-tone images (pseudo-spreading), which carried out in
