ABSTRACT:
An apparatus for displaying an operating state of a computer includes a controller for providing output of a read signal to receive data signals from a local bus. The controller analyzes the data signals and provides output of a display signal representative of the operating state of the computer based on the analysis of the data signals. An interface unit receives the data signals from a system bus, stores the data signals, and provides output of the data signals to the local bus in response to the read signal provided from the controller. A driving unit provides output of grid driving signals and segment driving signals in response to the display signal provided from the controller. A display panel variably provides an alphanumeric display indicating the operating state of the computer in accordance with the grid driving signals and the segment driving signals provided from the driving unit, and further provides iconic displays indicating the operating state of the computer in accordance with control signals provided from the computer.
