PROJECT LIGHTNING
Abstract
During this quarter, combination of the logic and the memory subsystems was effected and the resulting unified subsystem was operated. Several unanticipated problems were recognized and corrected. The electrical grounds used by each subsystem were not common, resulting in a 60 cycle circulating current. The known incompatibility of design between the two subsystems was further eliminated resulting in several major decisions concerning future work. Memory fabrication techniques did not allow for accessibility to the lower planes which contributed much to redesign requirements. The two subsystems worked together with the memory operating at a 33-mega cycle repetition rate. The 24-bit work line was operated for long periods of time; no difficulties were encountered.
