The entrance to the underground Columbia University Computer Center building
in 1982. You can't see the building, only the door.
Also not visible in the photo are the words "Computer Center" chiseled
on the small rectangular wall facing the viewer. Enter the door, go down
one flight of steps to the 2-Level, find the machine room. Go down another
flight to the 1-Level and this was the location of the former
SSIO area, now offices. The new Gym entrance is on
the left; Pupin Hall and Teachers College in the background, Uris Hall (the
Business School) on the right (all the windows are part of Uris Hall; the
Computer Center has no windows). In 1963 when the Computer Center building
was new, there was no new Gym and Pupin had a grand front lawn with ancient
spreading shade trees, similar to the ones in front of Math today.
When the IBM 360 mainframes were installed in 1967-69,
the entrance and much of the interior were demolished to make way for them.
