Neither can be hacked from the ground. Its hard enough trying to connect the damn maintenance laptop! Bring back the 777 MAT!
I was talking about the basic systems - GPS, Autoflight, Weather Radar, Comms etc. They all operate in basically the same way using similar technology. the only real difference between something like an A380 and a B757 is that instead of multiple boxes you have a single 'mainframe' computer with all the functions contained within that one computer system.
As for FBW - well the B757 did have FBW (Spoilers), in fact I believe it was the first Boeing passenger aircraft to have FBW installed.
