Bondeze Magnetic Wire for Memory-Plane Construction, 1954 August 27
MIT DIC 6889. Project Whirlwind Memo M-3005. The possible eventual breakdown of the Quadruple Formex insulation in memory planes due to the abrasive action of vibrating memory cores could be prevented by wiring the planes with Bondeze #3 Magnetic wire. The resulting plane would have the windings bonded together, forming a strong grid with the memory cores firmly cemented at the intersections of the wires.
Delta ns In Ceramic Array #1, 1952 October 14
MIT DIC 6889. Project Whirlwind Engineering Note E-488. It is possible to obtain two values of output voltage from a half-selected memory core depending on whether it holds a ONE or a ZERO. This fact places a limit on the size of a memory plane or, more specifically, the number of cores on one sensing winding which may be half-selected during a read operation.
Description of Memory Test Setup VI, 1954 October 11
MIT DIC 6889. Project Whirlwind Memo 6M-3097. Memory Test Setup VI is an assembly of Burroughs' test equipment designed to simulate computer operation of magnetic-core memories. It makes possible the dynamic testing and evaluation of both single memory planes and completed memories of sizes up to 64x64 registers and word lengths of approximately 20 digits.
Procedure for Preparing and Stripping Wires for MTC Memory Planes, 1953 April 6
MIT DIC 6889. Project Whirlwind Memo M-1957. The stripping of formex insulated wires used in memory plane construction has been greatly speeded up by a method which permits them to be stripped in bundles of 150 wires rather than singly.
Procedure for stripping wires for 64 x 64 memory plane modules, 1955 June 7
Division 6 Memo M-3654. The required procedure for preparing and inspecting wires used in the construction of 64 x 64 memory plane modules has been recorded for the benefit of shop personnel and outside vendors. Includes: wire stripping procedure, digit plane wire, sense wire, stripping the sense and digital wires, and wire inspection.
Specifications for 642 memory plane module frame, 1955 June 20
Division 6 Memo M-3699. Recording of the specifications to be met in the machining of 642 memory plane module frames for the benefit of shop personnel and outside vendors.
Test Results on the DCL Memory Plane, 1954 May 28
MIT DIC 6889. Project Whirlwind Memo M-2840. The DCL plane (C25) is compared with a standard MTC plane which has General Ceramics cores. Except for requiring slightly higher driving currents for maximum output, the DCL plane compares favorably with the MTC planes and could, in fact, operate as a substitute MTC plane without seriously impairing the system's margins.
The Construction of Memory Planes for the MTC Memory, 1953 June 10
MIT DIC 6889. Project Whirlwind Memo M-2225. Seventeen memory planes were built for MTC. Each has 1024 cores, 128 coordinate driving lines, a digit-plane winding, and a sensing winding. Four days were required to wire each plane with addition time for frame construction, inspection and testing.
Vacuum and Vibration Speed Assembly of Core Memory Planes, 1956 February
MIT DIC 6889. Project Whirlwind Controlled Distribution Memo 6D-107. Memory units and matrix switches using new square-loop ferrite material increase speed and reliability of digital computers. Storage units with arbitrary-access and read-out time of five microseconds or less makes stored-information rapidly available without scanning time required by other systems. Reprinted from Electronics, February 1956.
