File extension GFX description:
The Genigraphics presentation graphics was derived from a flight simulator designed by General Electric for NASA in the late 1960s The Computed Images System & Services division (CISS, to become Genigraphics) of General Electric delivered the first presentation graphics system to a customer in 1973. It was named the 100 Series, and was based on DEC's PDP 11 series of mini computer systems. The first Genigraphics systems(100 Series and 100A Series)used an array of buttons, dials, knobs and joysticks, along with a built in keyboard, as the means of user interface. The PDP-11/40 computer was housed in a tall cabinet and used paper tape for storing completed presentations.
