The customer sent us a AN/APR-36 RWR that bought from internet and wanted to put a photo in the position of the screen with symbols from a rwr in operation to use it in his Mirage F-1 cockpit (not a simulator) 

We suggested instead of a photo to make it play a video from a rwr of that era.The client accepted our proposal, so we removed all the old electronics and replace the burnt CRT screen with an LCD and drive it with a raspberry programmed to loop a video of a real rwr in action.

And this was the result!!!!!!!!
