Abstract: A new logic and storage circuit is provided for a terminal device such as a display or printer used in a data processing system. The circuit includes a shift register that is interconnected with a control unit by a coaxial cable or other two conductor system for transferring serial messages to the control unit and for receiving serial messages from the control unit. The register is connected in parallel with other components of the terminal device. The logic and storage circuit is provided with means for detecting data bits on the two conductor message line and for forming data bits on the line in response to the contents of the register. Means is also provided for decoding control word messages from the control unit and for receiving data messages or transmitting data or status word messages from the terminal device to the control unit.

Abstract: A circuit is provided for operating a keyboard in a selected one of four character sets: upper and lower case Latin and upper and lower case Katakana. The circuit responds to signals produced by the familiar Shift and Lock keys of a conventional keyboard. One of the shift keys is designated a Latin shift key and the other is designated a Katakana shift key. Depressing a shift key momentarily sets the keyboard to operate in the lower case of the character set identified by the shift key. For upper case, the operator either sets the shift Lock or holds the appropriate shift key while striking a character key. A specific logic circuit is disclosed.

Abstract: A plasma display panel has horizontal and vertical orthogonal drive lines disposed on opposite sides of a gas filled envelope. To achieve higher resolution in the plasma display panel and prevent cell to cell interaction during operation in the sustain or addressing mode, the horizontal and vertical drive signals applied to adjacent cells are phase separated such that adjacent cells are energized at different time intervals to isolate cell to cell interaction and thus provide a honeycomb effect.
