Hi xeontory, Magnox,
generally VFD Display is quite simple to drive,
you have to powered the filament, one side of filament: GND
Other side of filament: 2.5-3V DC
Anode and grids: 12-36V DC depend on the model.
These are some examples to determine what pin is use for and how to drive.http://www.instructables.com/id/Arduino-VFD-Display-Clock-Tutorial-A-Guide-To-VFD-/
