ASTRONAVIGATION COMPUTER RESEARCH.
Abstract
The feasibility of a magnetic-logic computer is reported. An improvement in reliability of from four to five times that achieved in equivalent semiconductor computers has been demonstrated by a substantial decrease in the number of active components. This decrease has been made possible by the use of four-phase inhibit logic and current steering in conjunction with microprogramming techniques. The most significant accomplishments of the program are: A biaperture ferrite element was developed for use in memories and registers in the temperature range from -55 C to +125 C. The element is employed in: (1) the NDRO, random access, electrically alterable program memory, (2) the NDRO random access data memory, (3) the DRO registers in the arithmetic unit. The feasibility of using single driver current pulses to accomplish multiple computer operations was demonstrated. This technique results in high reliability (low number of drivers) and low power consumption. A new method of developing basic computer timing pulses has been demonstrated in the Sequential Switch, which develops basic timing for computer operations while employing few active components.
