Applications of CRC-105 decimal digital differential analyzer

In the two years since the first digital differential analyzer was put in operation, it has been the complexity of filling and operating such machines, rather than any difficulty in coding them for a problem, that has constituted the main impediment to convenience and efficiency in their use. In filling some hundred-odd binary digits, one at a time, for each integrator information, the possibility of error is great. For instance, let us look at the binary number
