摘要： A video game includes apparatus for scrolling playfield objects appearing on the display unit of the game. The apparatus selectively offsets the address used to access an addressable random access memory containing data indicative of the TV picture displayed. The random access data, when accessed, is used to address a video data memory which provides the building block components of the video display. Further scrolling effect is obtained by selectively delaying the video data communicated to the video display unit.

摘要： A microprocessor based data processing system including a microprocessor, a memory unit, and a display unit is provided with a programmable graphics generator that transfers graphics information from the memory unit to the display unit in response to and control of a set of display instructions also stored in the memory unit. The graphics generator includes a first addressing unit for sequentially accessing the display instructions from the memory unit; a control unit for receiving, storing and decoding such instruction and for issuing supervisory and control signals in response to the binary state of each instruction; a second addressing unit for accessing graphics information from the memory unit in response to the supervisory signals from the control unit; and a third addressing unit for accessing movable object graphics stored in the memory unit.

摘要： A deformable switch keyboard assembly with a flexible unitary top member, a compressible intermediate switch assembly layer and a bottom member providing mechanical support for the intermediate assembly and mechanical isolation for the switching function.The top member has a plurality of switch site defining regions extending in a first direction and located in a predetermined array to define the keyboard. The intermediate switch assembly has a plurality of switch sites each underlying a different one of the top member projections. The bottom member has first and second sets of projections extending toward the top member, each of the first set of projections underlying a different one of the switch sites and providing a compression contact beneath the intermediate switch assembly when the corresponding top member region is actuated to advance in the first direction. Each of the second set of projections is located intermediate different adjacent ones of the switch sites and is longer than any of the first set of projections in order to provide mechanical isolation between an actuated switch site and the remainder of the switch sites.

摘要： A decoding circuit is coupled to the signal lines that communicate address signals to a memory unit. When a predetermined address is communicated, the decoding circuit produces a supplemental signal that is coupled to the memory unit and used to select one of a plurality of groups of memory locations. The communicated address signals specify the memory location of the selected group to be accessed.

摘要： A single device for driving a pair of floppy discs, preferably the smaller mini floppy discs, is disclosed herein and identified as a dual floppy disc machine. A drive motor is coupled to a pair of rotatable spindles mounted side by side. The spindles receive respective floppy discs thereon, and are driven at a speed not to exceed 50 rpm, much lower than the speed of conventional floppy disc machines. A pair of read/write heads are provided which have a capacity of reading no more than 20,000 bits per second, again well below conventional rates but sufficient for the speeds used in the present invention. A single carriage has both read/write heads mounted thereon in spaced relationship, and is moveable along an axis bisecting a line connecting the centers of the spindles. As a result, the read/write heads are moveable in unison radially relative to the respective spindles. A stepping motor is coupled to the carriage to move the carriage along its axis. The pair of floppy discs are clamped to their respective spindles, and the read/write heads are biased against the respective discs so that both discs can be utilized.

摘要： Apparatus for producing a plurality of audio sound effects such as shots, explosions, and airplane and car sounds, used in electronic games utilizes a variable clock driving a variable digital noise generator whose audio output amplitude is shaped by either of two types of control units. In one type the density or duty cycle is varied by selectively ANDing together outputs from a polynomial counter. In a second embodiment a digital to analog converter utilizing gated resistive summing provides the amplitude control the gates being driven by a four bit data register which in turn is driven by the game control means.

摘要： An electrical control device having a joystick or lever manually movable in the X and Y directions to actuate a pair of electrical components having respective rotatable shafts. The controller includes a housing having a top cover provided with an opening through which the lever extends. The lower end of the lever is pivotally mounted in a socket on the bottom of the housing and a ball joint is carried by the lever intermediate its ends. The ball joint is pivotally coupled to a control plate shiftable in the housing beneath the top cover, the plate being biased into an equilibrium position by a number of leaf springs normally engaging respective side margins of the plate. The plate has a pair of slots in its lower surface, the slots being mutually perpendicular and vertical projections on the outer ends of a pair of bell cranks are shiftably received within respective slots in the plate. The bell cranks are coupled to the rotatable shafts of respective electrical components so that, when the plate is moved in any one of a number of different directions upon manual movement of the lever, one or both of the rotatable shafts of the electrical components are rotated to actuate the components.
