Indicator Display

The display device is for use with an information handling system. The device displays the various conditions within a system such as the state of bits in a register, triggers, memory bits, or the state of any other binary component within the system.

The conditions are displayed by indicators 2 which can be incandescent lamps, electroluminescent devices, light-emitting diodes or any other similar devices. Those indicators 2 are turned on when the conditions they represent are in the 1 state and are turned off when in the 0 state.

The display includes two-hundred and forty indicators 2 which are grouped in ten rows in the Y direction and twenty-four columns in the X direction. Indicators 2 indicate different conditions depending upon what parts of the system to which the indicators are connected. If all the indicators are connected to different sets of conditions, then indicators 2 can indicate any multiple of two-hundred and forty conditions depending upon the number of different connections which can be made to such indicators. For example, if the indicators are connected at different times to ten sets of system conditions, then a total of 2400 conditions is displayable.

Since the indicators represent different conditions at different times depending upon what conditions they are connected to, optical images bearing indicator-identifying indicia are projected adjacent the indicators on screen 33 via an optical projection system including lens...
