I'll jump in here. I've flown the 73N, as well as several more modern Boeing designs. I was shocked when I displaced back to the -800. There must be 3 times the switches on the overhead panel. There's no EICAS, so you get to play "I've got a secret" when the lights and bells go off, despite the fact that in the bowels of the E&E compartment, it knows exactly what's out of sorts.

That cockpit was left in it's antique state for one reason: so it could be flown as a common type with the '60s era 737-200. Boeing could have put a 777 cockpit on it, but then SWA would have had two categories.
