Vector graphics display systems of the 1970s that drew lines directly on screen in real time. Larry Cuba made the Death Star trench animation for Star Wars on one in Chicago.
The Vector General had a bunch of analog controls. You could actually turn dials and slide sliders and push buttons to start things up and stop them. And this is unusual for computer graphics.

I entered the program right after Larry Cuba had finished the trench scene for Star Wars on the Vector General. I did my first work on that.
