A character-based display controller, which is capable of providing variable width text characters, includes a ROM embedded with pattern and attribute codes, and a logic control circuit enabling multiple modes of interpreting the data in the character memory. The logic control circuit also enables bypassing the character memory thereby permitting a bit-mapped display mode.

On-screen display controller

A joystick controller for use with a home electronic video game produces electrical control signals in response to manipulation of a control stick. Within the controller housing a pair of light sources produce orthogonal light beams which are detected by respective light detectors to produce the control signals. A shutter, actuated by movement of the control stick, regulates the light falling onto the light detectors to produce control signals indicative of control stick positions.
