Joint MIT-IBM Meeting on Memory-Core Measurements, September 1-2, 1953

Abstract

A two-day joint meeting was held to discuss measurement and evaluation of ferrite memory cores by MIT and IBM. During the first day, at Poughkeepsie, the specifications for selection of cores for the WWI bank-B memory and the second MTC memory were reviewed. The cores are selected to have disturbed-one voltages within plus or minus 15 percent of the mean. Modified specifications for RCA-Victor cores were discussed. Plans for a "round-robin" on core measurements were made to coordinate measurements at MIT, IBM, (Plant 2 and High Street, General Ceramics, and RCA Victor. During the second day, at RCA Victor in Camden, measurements and progress by RCA were discussed. The cores there look good after preliminary observations, but techniques and test equipment must be improved to permit refined evaluations.
