A general purpose controller suitable for use with an electronic amusement game having a raster scan display receives game data from the game during vertical blank periods, the game data specifying object images and their screen positions desired for the next display in the sequence of raster scan displays. The controller then reads color/intensity information for each display pixel out of permanent memory at the time the pixel is displayed on the raster scan display surface. An embodiment is described capable of controlling up to 32 object images in the play of a game.

General purpose display controller for electronic games

An improved rowing exercising machine is disclosed. The machine has a mechanical apparatus for accepting user stroke movements; each stroke has a power portion and a return portion. The mechanical apparatus converts the energy from the user stroke movements into rotation of a flywheel. In order to closely simulate the feel of momentum in actual rowing activity, electronic circuitry is used to control a brake to apply a force to slow the motion of the flywheel. The amount of force supplied by the brake is independent of the speed at which the user is rowing the machine and is under software control. The brake force can be varied to additionally slow down the rotation of the flywheel during the return portion of a stroke. The rowing machine includes a video display which gives the user the sense of competitive scull racing. The display shows an animated rowing figure having stroke movement synchronized with the user stroke movements. A pacer rowing figure is also displayed. During the rowing exercise, the distance separating the rowing figures depends on the user stroke movements and on pre-set pacer motion.

A high speed CPU/sequencer for use in a video game provides multi-channel binary output for display control purposes. The CPU/sequencer includes a macro-section that is user programmable with macro-instructions and a micro-section that is user programmable with micro-instructions. The CPU/sequencer is responsive to display information provided by a game microprocessor during a brief handshake period and carries out display computations independently of the game microprocessor, at higher speed, and using larger binary data words.

High speed CPU/sequencer for video games

A line buffer system can display a large number of objects and a background in connection with the play of a video-type game. The system may be used with a microprocessor. Game data is transmitted from the microprocessor during a brief 'handshake' operation which may occur at any time. The game data specifies the objects and background to be presented and the screen location of each. The objects and background, respectively, are stored as rectangular blocks in two memories. At least two buffers are provided, each buffer capable of storing data to represent one line of the picture. The system operates upon the game data to load the buffers in real time during picture drawing and just prior to picture drawing. One buffer then outputs a data stream to provide real time control of the drawing of one line of a picture. A flip feature provides for inverting any object or an entire picture about a vertical or horizontal axis, or both.
