DescriptionTektronix graphic terminal (1972).jpg |
You use a terminal to 'talk' via a telephone line to your computer which is somewhere else, as was generally the case around 1970. This Tektronix terminal was the first on which you could not only show text but also computer-generated images. But these were only static line drawings in green.
