The keyboard driver also tracks the Shift, alt and management state of the keyboard. The first computer keyboards were for mainframe computer knowledge terminals and used discrete electronic components. The first keyboard microprocessor was introduced in 1972 by General Instruments, however keyboards have been using the one-chip 8048 microcontroller variant because it turned available in 1978.
