The HP 9845C from Hewlett-Packard was one of the first desktop computers to be equipped with a color display and light pen for design and illustration work. It was used to create the color war room graphics in the 1983 movie WarGames. [4] [5]
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. [1] 4913 colors were available. [1]
The system is a big-endian 16-bit architecture, the BPC, with roots in the HP 2116A which were one of the first 16-bit microprocessors created. [6]
The display showed 8 soft keys on the lower end of the screen, 39 alignment controllers behind a door enabled fine tuning of color convergence. [1]
The speed of the builtin BASIC language was accomplished by implementing time critical parts of it in CPU microcode. [1]
A builtin tape cartridge device with a capacity of 217 kB and transfer speed of 1440 bytes/s enabled storage of data. [1] Average access time for the unit is 6s and a rewind end to end takes 20s. The directory is stored in r/w memory to enable quick access. [7]
