The HP 9845C was one of the first desktop computers in 1980 equipped with color screen and light pen for design and illustration work. It was used to create the color war room graphics in the 1983 movie WarGames.
The attached HP 98770A color display enabled the color graphics with its own CPU and separate power supply, a vector generator based on the AMD2900 bit-slice architecture, graphics memory with three planes of 32 kB each, the connection interface to the mainframe consists of a direct data bus attachment, and a light-pen logic. 4913 colors were available.
