Lincoln Laboratory. Division 6

Scope and Contents MIT DIC 6889. Project Whirlwind Memo M-2736. A memory system in which the memory functions (remanence) and the selection function (nonlinearity) are performed in separate cores may have the following advantages over the present (coincident-current) system: 1) Much broader tolerances on core acceptability 2) Reduced noise out of the memory array 3) Larger signals out of memory 4) Shorter memory cycle time Some of the costs may be: 1) Two or three times as many cores required 2) More...

Scope and Contents Project Whirlwind Memo M-2387. This note contains most of the important points discussed at a Joint meeting of the IBM-MIT circuit design groups on August 19, 1953. The main points made at the meeting were: a. High-Speed Flip-Flop: The only remaining circuit problem is to eliminate a 16 volt noise pulse which occurs when a set trigger is applied to a flip-flop already in the set condition.* b. Gate Tube Circuit: 1. More data must be taken on the gate tube circuit pulse transformer...

Project Whirlwind Administrative Memo 6A-174. Memorandum M-2704 which outlined the distribution procedures for Division 6 Memoranda while the Division was located in Cambridge is now obsolete. The dispersion of Division 6 personnel at Lexington required that new procedures be established to meet the new conditions and increasing organization. This memorandum outlines the current distribution procedures in effect.

Scope and Contents Project Whirlwind Memo M-2704. The progress and degree of success of any project requires that all interested personnel be kept informed on all phases of the latest engineering developments, which may or may not affect their particular phases of work with relation to the end result. It is therefore very important that proper distribution procedures be established to insure that the proper interested personnel receive the latest available current distribution procedures in effect for all...
