Yup I still have my old SB controller and pedals; I dig them out of the closet every now and then. The original SB was set up as a simulator that tried to mimic "real" life as much as it could; for example if you didn't eject from your exploding VT (vertical tank is what this game called it's mechs) your character was killed and made unplayable; you would have to start a new campain with a new character. The original price tag was around $300 and that bought you the 3ft wide, 38 button/switch, 3 pedal control system and the game. If you look carfully at the controller you will even see a button for the windshield wipers; and if I remember correctly the VT start up process required 3 buttons and 5 switches to be manipulated in the correct order to be successfull.
The top two pictures you posted are from Steel Battalion: Heavy Armor and the bottom on is of the original SB control setup. SB: Heavy Armor is a different game and is reported to make use of the standard xbox 360 controller and the kinect at the same time.
There is a way to use the old SB controller to play Mechwarrior 4 but it is beyond my meager computer skills.
