Abstract: A game apparatus is disclosed having a one-dimensional array of LED's which are sequentially activated in first and second sweep sequences which proceed toward first and second goal indicators, respectively. First and second buttons are provided which operate to reverse the first and second sequences, respectively, and the object of the game is for each player to operate his button before the appropriate sweep sequence causes his goal indicator to be activated. The rate of each sweep is variable and a player can select a higher sweep rate for his opponent by delaying his reaction until a relatively later time in the sweep sequence. The score is displayed on the same indicators as are used to play the game, and successively higher scores correspond in sequence to the sequence in which the indicators are activated during play.

Abstract: There is disclosed a computer system including a storage means such as a random access memory (RAM) for receiving data to be displayed upon a display means, e.g. a color cathode ray tube, a microprocessor for control of the computer system operations, and viewer input devices such as a control stick or keyboard, whereby the viewer may respond selectively to the data displayed upon the display means. A limited capacity storage unit, illustratively in the form of a tape cassette, stores data in the form of a program for permitting the viewer to store useful material in the form of a repository, such as a Christmas list; the program to be displayed by the display means can assume any of a limitless number of programs and may be adapted to an exceptionally wide range of uses for the home, office or school. The computer system permits the viewer to respond as through the input devices, to the material being displayed, whereby subsequent material may be effected.
