ABSTRACT:
A keycode translation system is disclosed in the form of a hardware system for providing translation between the keycode sent to the keyboard controller of a computer, such as a personal computer, and the code sent from the keyboard controller to the CPU of the computer for processing. A control ROM is used to select translated keycode signals from a keycode look-up table under the control of a program counter and keycode signals from the keyboard. These translated signals then are supplied through an accumulator to the CPU of the computer.
