The Columbia Computer Center Machine Room


The Columbia Computer Center IBM Machine Room, early 1980s, after the IBM 360/91 was removed. Visible at right center is some of the last surviving punch-card equipment. Off to the far right is the Gandalf PACX terminal switch. Tape drives to the left and the rear; printers in the foreground; the operator terminal area in the center.
