MIT DIC 6889. Project Whirlwind Memo 6M-3375, Supplement 1. Supplement to the bi-weekly progress report of Division 6 research teams.
MIT DIC 6889. Project Whirlwind Memo 6M-3405, Supplement 1. Supplement to the bi-weekly progress report of Division 6 research teams.
Project Whirlwind Memo 6M-4359. A summary of EPSCOM program activity is included along with reports on several programs. One new programmer, Marilyn Lynch (BTL), has joined EPSCOM bringing the EPSCOM force to 40 people.
Project Whirlwind Memo 6M-4323. EPSCOM now includes 38 people. A chart showing most of the EPSCOM programs includes scheduling information.
Project Whirlwind Memo 6M-4289. EPSCOM manpower now stands at 35 people. Progress on all programs is satisfactory.
Project Whirlwind Memo 6M-4371. The EPSCOM force still stands at 40 people. A summary chart and schedule is included along with reports from programmers..
Project Whirlwind Memo 6M-4345. EPSCOM now includes 39 people. A report on most of the EPSCOM programs is given.
Project Whirlwind Memo 6M-4307. EPSCOM, now Group 66, with 37 people including a new secretary at Murphy Hospital, is being reorganized into 3 subsections.
MIT DIC 6889. Project Whirlwind Memo M-2275. The equation of motion for a cylindrical domain wall has been derived utilizing the Lagrangian formulation. Additional terms enter the equation of motion for a cylindrical wall that do not appear in that for a planar wall.
Project Whirlwind Memo M-2744. Memorandum on a new policy for the establishment of procedures for the adoption of new procedures for the AN/FSQ-7 Program.
Division 6 Memo M-3738. A one-year extension of Subcontract No. 49 with the Philco Corporation was recommmended to (1) continue research aimed at establishing the reliability of the surface-barrier transistor and improving its performance in digital-computer circuits, (2) establish specifications for a computer surface-barrier transistor, (3) develop transistors for driving magnetic-core memories, and (4) develop digital-computer basic circuits.
Project Whirlwind Limited Memo L-117. Personnel estimate for Fiscal 1954 completed for Division 6 to show anticipated personnel needs existing in June 1954 and the estimated average needs during the previous fiscal year. Estimates of extraordinary expenses for the year were submitted to Walter DeQuoy in Memorandum L-104, dated 29 June 1953.
Division 6 Memo M-4089. Two possible memory element geometries — the thin film and the toroid — are considered. The calculations show that under certain conditions the thin film geometry may be preferable for use in a very high-speed memory. Includes: introduction; theoretical ruminations; discussions and conclusions.
MIT DIC 6889. Project Whirlwind Memo M-2649. A graphical summary of some of the magnetic data which were collected during 1953 on the MgO-Fe₂O₃-MnO System is presented.
Project Whirlwind Memo M-2665. Consideration is being given to have MIT provide assistance to IBM with engineering development of specific items of the system. Decision on the switching system for drum circuits has been postponed. An engineering model of a mapper developed by IBM has been installed in WWI for test purposes.
Project Whirlwind Memo M-2837. Meetings with Air Force ADC have led to a plan for implementing the Air Division Combat Operations Center with a simplex FSQ-7 and a supplementary large board (projected) display. A procedure to formalize the processing of information thru the Control office to DES, Air Force, etc. is being prepared. Modifications to the display system have resulted in a reduction of approximately 3000 tubes. MTC will be moved to Lexington starting June 7.
Project Whirlwind Memo M-2651. Decision on the display system and basic circuits for the instruction control frame were reached during the week. A revised basis for release of design and constructions by IBM in advance of Lincoln approval has been proposed by Project High. Initial negotiations leading to an Air Force contract for two duplex centrals (in addition to the XD-1 and XD-2 systems) have been started.
Project Whirlwind Memo M-2470. Two situations urgently need attention at the present time. The vacuum tube count for a central has become rather large, and every effort should be made to see what can be done to reduce the count. The space required for XD-1 exceeds the space available in the basement of building A, and several alternate arrangements are being investigated. Progress in other fields is fairly satisfactory.
Project Whirlwind Memo M-2760. IBM will furnish monthly status reports relative to time schedules. MTC will move about June 1 and be operative again about July 15. An initial proposal on the duplex central will be distributed about May 1. A separate drum field will be used for Mark X and Fine Grain Data inputs.
