A view showing the gas-filled tubes that rectify the D.C. power for the ENIAC. The right-hand cabinet contains the power supplies for operating the test bench, a unit that is used for repairing and testing the plug-in chassis without interfering with the operation of the machine itself. Leo Clinton, maintenance electrician, is shown checking the operation of the thyratone, which can be seen glowing.
Caption: 'Girl on left is inserting a deck of cards containing initial data on which the ENIAC will operate, while girl on right is removing a set of cards which represent the result of the preceding computation." Women identified: Betty Jennings (left) and Frances Bilas (right), two of six women chosen to work as the main programmers for the ENIAC.
