It become much fuller as the years passed. This is the key punch room in the Computer Center, where users could prepare their card decks using the key punch machines against the back wall. An IBM 407 is on the right. I have no idea what the big black thing is behind the 407. Another scene from the key punch room.
Right center is a card sorter .
On the left is a case of plugboard programs for the sorter. Another view of the key punch room.
