The Nondestructive Read System was used on relatively low power levels. Good discrimination between ONE and ZERO could be achieved with β field currents as low as 20 ma and readable signals were contained with 7 ma.

In the MTC memory, the amplitude of the output voltage is sensed to tell if it is a "one" or a "zero". If the slope of the output is sensed, the "one" to "zero" ratio may be greater.

Study is underway to reduce the cost of the prototypes to keep within the Project High budget. Items to receive top priority in the next few weeks are listed.

This memo is a summary of an appendix to a Group 63 seminar on magnetism. Topics include calculation of spontaneous magnetization in the region of the curie temperature and the Brillouin function.

This memorandum outlines procedures for transferring principal responsibility from MIT to IBM.

A meeting of the Joint IBM-MIT Standards Committee on Materials and Processes, held June 4 at M.I.T., agreed on certain soldering and wiring methods. The area of agreement was wide, and the following text outlines what was ...

Aside from all second-order effects, there is an unwanted output voltage inherent in magnetic-memory arrays due to cores whose half-selected output voltages do not cancel. This voltage is due to two cores in the arrays ...

Considerable attention was given to a review of the power equipment. The Charactron display system has been selected for AN/FSQ-7. The schedule for the MTC construction work is outlined.

Bi-weekly progress report of Digital Computer Laboratory research teams.

Magnetic Devices, Inc. of Fredrick, Maryland was visited to determine whether rotary relays showed enough promise for either marginal checking or power distribution use to warrant further investigation. It was our conclusion ...
