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.

Scope and Contents

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.

Scope and Contents

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.

Scope and Contents Project Whirlwind Memo M-2790. The Transition Systems inputs, duplex operation concepts, weapons control capabilities, phone line transmission requirements were discussed at a recent conference with Air Force and ADES representatives. The display selection frame has been eliminated in favor of having the necessary hardware in each console. Consoles in the operations areas will be wired as a single group and therefore all will receive display information from the same computer. Construction...

Project Whirlwind Memo M-3002. Concurrence with IBM is scheduled for display system and MRI specifications. MTC has been reassembled and will be fully operational by September 1. Components of the 13 most frequently used circuits are to be released for ordering (for 2 Production Systems) in September. First floor equipment layout for production systems is being finalized. Requirements for Power System for production system has been released through the Production Coordination Office.

Scope and Contents Project Whirlwind Memo M-2574. SDV demodulator circuitry has been reviewed and accepted. Phone line transmission characteristics are being determined in conjunction with Bell Laboratories Project ADES personnel. Simplification of equipment to handle inputs having a relatively slow data rate is under study. Coordination of output system and equipment development is to be done by a joint IBM--Div. 6--Div 2 committee. Formalizing of the release for design completion and for construction of the...

Scope and Contents

Project Whirlwind Memo M-2595. Specifications for the display system, the power system and the internal memory will be prepared. Output system work will be coordinated by a joint MIT-IBM committee. The Order Code for FSQ-7 has been agreed upon by MIT and IBM programmers.

Scope and Contents

Project Whirlwind Memo M-2691. Arrangements to have prime responsibility for certain engineering work placed with MIT have been made in the interest of insuring adherence to July '55 date for system operation. Regular air transportation between Poughkeepsie and Cambridge is expected to start approximately March 1, 1954. Consideration is being given to possible alternate sources for Charactron tubes.
