Abstract
A hand-held electronic program playing device having a flat panel electro-optical display unit incorporated in a housing, is disclosed. Circuitry suitable for driving the display unit and manually operable controls for providing a plurality of control functions are incorporated in the housing. A replaceable cartridge unit which fits into and mates with the housing incorporates a microprocessor and supplementary circuitry. The cartridge unit can include a transparent overlay which incorporates one or more graphic patterns. When the cartridge is placed into the housing the overlay is disposed relative to the display unit so that the visual image of the display unit is viewed through the overlay. The microprocessor and overlay in the replaceably cartridge define the program such as a game that can be played by the housing and cartridge combination.
