1. Apparatus for generating an audible chime to apprise a motor vehicle operator of the status of a motor vehicle comprising:
- a microprocessor which executes an operating system that includes a program for monitoring one or more input pins and thereby monitors one or more status conditions of a motor vehicle;
said microprocessor operating system further executing a program for generating repetitive output signals from a single microprocessor output pin at an audible chime frequency in response to the monitoring of the one or more status conditions; and
amplifier means coupled to said single microprocessor output pin for amplifying said repetitive output signals and coupling amplified output signals to a speaker for converting said amplified output signals into an audible tone having said audible chime frequency.
