Using three of the more advanced electronic storage or memory devices -- cathode ray tubes, magnetic drums and magnetic tapes -- the calculator can multiply and divide more than 2,000 times a second and can add and subtract more than 16,000 times a second. While solving a typical problem, it is capable of performing 14,000 mathematical operations a second. In the center of the installation shown here is the Electronic Analytical Control Unit, and at its right is a card reader. On the left are Magnetic Drum Storage Unit and Electrostatic Storage Unit. In the group at the right are two Magnetic Tape Readers and Recorders, the Alphabetical and Numerical Printer and the Card Punch. Two Power Supply Units are not visible.".
