Like the mid 1970s Tektronix 4014 storage tube graphics display terminals. Saw one that was retired but still operational in early '00s used originally for CAD.

Like the mid 1970s Tektronix 4014 storage tube graphics display terminals. Saw one that was retired but still operational in early '00s used originally for CAD. Interesting how back then you could draw a circle in a box then morph the box (using scroll wheels) into a rectangle to form an ellipse.
