The graphic video generator

The widespread use of minicomputers in widely diverse applications has resulted in the need for many peripheral devices to allow user communication with the machine. Data passing from the computer to the operator may be in the form of paper tape, punch cards, line printer listing, voice output, and video display to name but a few. Many applications require that the computer output be in a “hard copy” form such as a line printer listing. Obvious examples include such areas as order processing, invoice preparation, and payroll distribution.
