Abstract

There is disclosed herein an apparatus for displaying data and communicating with another data processing device via a parallel port or over a long distance communications network via a full duplex modem, said computer terminal utilizing a microprocessor for programmed control of the terminal. The terminal is capable of displaying information on a standard black and white television set and utilizes a keyboard for entering information to be displayed or sent to the main data processing system. Limited graphics with sixty four graphics patterns are also available by using the microprocessor chip to scan the keyboard and communicate with the modem and parallel ports, and by utilizing a standard television set instead of a cathode ray tube, substantial material cost savings can be made in building the terminal which could be built for under $250 in parts in 1979.
