Устройство работает следующим образом. .The device operates as follows. .

С помощью клавиатуры 22 оператор устанавливает нужный режим работы устройства. Затем при нажатии любой клавиши клавиатуры 2 производится матричная шифрация по строкам и _ столбцам позиции нажатой клавиши и эта информация поступает через шифраторы 6 и 7 на информационные входы регистра 10* Одновременно все выходы строк клавиатуры 2 собираются на элементе ИЛИ 4 и поступают на запуск блока 3 на вход элемента И 16. При отсутствии блокировки устройства (формирователь 24 не срабатывает) сигнал с выхода элемента И 16 устанавливает в 1 триггер 9, который снимает с.входа установки в “0 регистра 11 обнуляющий сигнал, и импульсы генератора 15, поступающие на тактовый вход регистра 11, переписывают уровень логической 1, жестко’¹ прошитый на входе регистра 11 на его выходы (Qи Q^).После этого регистр остается в этом состоянии до прихода следующего обнуляющего сигнала* Четвертый элемент И 19 и инвертор 21 формируют одиночный импульс, который через элемент ИЛИ 5 поступает на шину прерывания ЭВМ. Этот импульс одновременно стробирует запись в регистр ГО и устанавливает в ”1 триггер 8, который инвертирующим выходом, соединенным с входом элемента И 18, блокирует выработку нового сигнала прерывания пока не происходит считывания информации из устройства.Using the keyboard 22, the operator sets the desired mode of operation of the device. Then, when any key of the keyboard 2 is pressed, matrix encryption is performed on the rows and _ columns of the position of the pressed key and this information is transmitted through the encoders 6 and 7 to the information inputs of register 10 * At the same time, all the outputs of the rows of the keyboard 2 are collected on the OR 4 element and are sent to start block 3 to the input of the element And 16. In the absence of blocking the device (driver 24 does not work), the signal from the output of the element And 16 sets 1 trigger 9, which removes the setting input from “0 register 11 zeroing signal, and pulses are generated and 15 received at the clock input of register 11, rewriting a logic level 1 fixedly ^'1 stitched at the input of register 11 to its outputs (q and Q ^). After this register remains in this state until the next nulled signal * The fourth AND gate 19 and the inverter 21 form a single pulse, which through the element OR 5 enters the computer interrupt bus. This pulse simultaneously gates the recording in the GO register and sets trigger 8 to ”1, which blocks the generation of a new interrupt signal by inverting output connected to the input of element And 18 until the information is read from the device.

После прерывания ЭВМ через блоки 12, 13 и 17 сигналами управления с группы управляющих входов устройства 34 производится считывание информации с выходов регистра 10, шифратора 25 и с -неинвертирующего выхода триггера 8 по группе 32 выходных информационных шин устройства. При срабатывании формирователя 23 и одновременном нажатии любой клавиши на клавиатуре 2 производится через элемент И 17 и ИЛИ 5 автоматическое формирование сигнала прерывания. Выходы шифратора 25 и формирователей 23 и 24 через элементы группы 26 поступают на индикатор 28.After the computer is interrupted through blocks 12, 13 and 17 by control signals from the group of control inputs of the device 34, information is read from the outputs of the register 10, the encoder 25 and the non-inverting output of the trigger 8 through the group 32 of the output information buses of the device. When the driver 23 is triggered and any key on the keyboard 2 is pressed simultaneously, the interrupt signal is automatically generated through the AND 17 and OR 5 element. The outputs of the encoder 25 and the shapers 23 and 24 through the elements of the group 26 are received on the indicator 28.

Сигналы о состоянии режимов ЭВМ, поступающие по шинам 33, записываются сигналом управления с группы 34 входов в регистр 30 блока 35. Выходы регистра через узел 27 соедийены с индикатором 29. При отжатии клавиш схема устанавливается в исходное состояние после считывания информации в ЭВМ. В режиме символов оператор · производит набор, редактирование и ввод текстовой информации в ЭВМ. В режиме графика производится ввод в ЭВМ необходимых точек. Управляющие клавиши клавиатуры 2 инициируют вThe signals about the state of the computer modes received via the buses 33 are recorded by the control signal from the group of 34 inputs to the register 30 of the block 35.
