This blog about Airport history mentions that sometime after the old terminal opened they did renovations including adding escalators (that were not there originally). And:
The courtyards and original observation deck that acted to bring in more natural light and display public art were eventually filled in to create more office space. Added security requirements further cut off the front of the building from the rear.
This site has some great pics of the old terminal. Alas, none of the observation deck
