coil pack engine or distributor engine ?

Hi, currently looking to sell my x reg micra S 1.0 and have been asked by a prospective buyer whether the engine is coil pack engine or distributor. Any thoughts on how I'd go about finding this out? (apologies if this is an obvious question - i'm not particularly mechanically-minded!).
 
Do you have 4 leads on the top off the engine that go to a round think on the side of the engine? Or do you have 4 black square boxes on top of the engine? Or post a pic of the engine and we can tell you.
