The ED-800 is a large format, 5x6 inch display that uses a high resolution CRT to display ADI or MFD information. The ED-800 is panel mounted and consists of four electronic component plug-in assemblies, a low voltage power supply assembly and high voltage power supply assembly. The ED-800 display has light sensors for automatic dimming. A single EDZ-805 system is comprised of two ED-800 Electronic Displays that are identical and interchangeable, except when used as an ADI with an inclinometer attached to the bezel.

The maximum weight for the ED-800 is 10.3 pounds. The ED-800 measurements are as follows width 6.08 In. length is 10.50 In. and height is 5.08 In. The ED-800 display unit is capable of operating in either raster scan or stroke writing modes. In the stroke writing mode the deflection amplifiers operate as current output power stages. The deflection yoke currents are sampled and fed back to the input of the power stages to provide deflection amplifier for each mode of operation. The deflection amplifier output stages, in both the vertical and horizontal axes, are constructed using complementary power transistor for high power gain, hence reduced component count. Circuitry is contained within the deflection system to provide for the "pincushion" linearity correction required by the CRT physical geometry. All of the display unit deflection signals are fed through a multiplexer. This allows the display to be driven from two different symbol generators as required when operating in the reversionary mode.
