ABSTRACT:
An adapter electronics circuit that converts signals from a pointing device into codes corresponding to keyboard cursor key actuations. In addition to the pointing device signals, the adapter electronics also accepts all key codes generated by the keyboard and passes them on unmodified to the computer. The adapter electronics plugs into the same terminal on the computer where the keyboard is normally connected. In this manner, all normal keyboard functions are available to the user as well as the use of the pointing device through the normal keyboard terminal on the microprocessor. Most commercially available application software accepts the cursor key codes presented to the computer.
