An overrun error system detects when a keyboard, attached as an input/ output (I/O) device to a computer system, is operated successively, whereby servicing of the first keystroke is not completed prior to the operation of a second keystroke. Such a condition may occur when two or more keys are struck simultaneously, or when keys are struck at a rate exceeding the servicing rate. The overrun error system includes provisions for notifying the keyboard operator of the overrun condition and for error recovery.
