Abstract
An adapter device, for use with a standard personal computer having affixed thereto a keyboard, is comprised of a molded rigid panel which is provided with a plurality of over-sized keys. The adapter is intended to simplify standard personal computer input methods by providing an input devise with a fewer number of Adapter keys than a standard keyboard. The adapter keys are also larger than standard keys. Raised spines on the under side of the adapter secure the adapter to a standard computer keyboard. Each of the keys on the adapter are attached via hinge along one side of the key. Depressing any of the adapter keys will cause that adapter key to contact the keys of host keyboard in a prescribed manner. An accompanying simplified software program is installed on the personal computer to work in conjunction with the adapter.
