Equipment with the craziest front panel.....

My vote is the ADVANTEST D3286 Pulse Pattern Generator/Error Detector

Your image tells only half of the story since it doesn't show the generator device. A working system has the D3186 and the D3286! And one might think the complete user interface is "on screen" but it isn't. There are lots of arrow keys to select modes..

When I was young I repurposed this nice front panel of what had been a "Liquid Scintillation Spectrometer" sporting dekatron tubes for numeric display.
