Abstract
A pattern display system is disclosed which includes a keyboard for the manual entry of data representative of the patterns to be displayed, a microcomputer for accepting the entry data and for controlling the display system, a random access memory for storage of the entered data, audio circuitry controlled by the microcomputer for accepting data to provide audio signals representative of stored data, coding/decoding circuitry for the transfer of stored digital data to or from a tape recorder, and video circuitry utilized under the control of the microcomputer for the visual display on a cathode ray tube (CRT) of the patterns represented by the stored data. Specifically, the video circuitry includes read-only memories which are controlled to provide video pattern information in response to the stored data which represented desired patterns and timing information for the CRT.
