F5 Interface Card

A number of the Northrop F5's were used for training in the USA and were due an avionics refit. As a part of that refit, an interface between a radar system and HUD needed to be created.

This was a simple interface card to connect the radar system to the HUD.  Essentially the radar system had an XY analog output, but the signals were of the wrong polarity.  So the interface card buffered the signals and then inverted them, and buffered them out to the HUD.

The design was a quick and easy one, compared to some of the others.
