TX-2 Project

Re-creating the historically important TX-2 computer

Lincoln Laboratory Progress Reports

This page lists Lincoln Laboratory Progress Reports relating to the TX-2 computer. Work on the TX-2 moved between several divisions.

Division 6 (Digital Computer)

Division 6 was the division which designed and began to build the TX-2 computer. It was also responsible for maintenance of the Whirlwind I computer and development of computer systems for the SAGE project.

Division 5 Quarterly Progress Report 1961-06-15 (DDC No. 260633)

From Computer Abstracts 1961-12 Vol. 5, 12:

A quarterly progress report (March - May 1961) of Lincoln Lab., M.I.T. The FX-1 test computer was assembled. A partial checkout of the central computer was made. The machine’s magnetic film memory is being checked out, prior to installation. Barring unforeseen difficulties, FX-1, with its planned 0.2-microseconds read-write memory cycle time, will soon be in operation. Within the past quarter TX-2 was used on Projects MIDAS and Mercury, on a pattern recognition problem and by the Research Laboratory of Electronics (M.I.T.) on an adaptive programming problem. Work on sequential coding (SECO) for two-way communications systems continue in two phases: (1) the construction with evaluation of a single decoder, and (2) the design, construction and evaluation of a two-way system. A number of improvements in both the automatic speech recognition activity and in the programs for computer interpretations of natural English text (BASEBALL) were observed. A new version of the degarbler, a computer program for automatically correcting errors in English text, was developed which promises to correct substantially more errors than earlier versions.

Beginning 1965-05-15, the Quarterly Progress Report for Division 2 was replaced by a Quarterly Technical Summary report on “General Research”. It covered divisions 2 (Data Systems), 3 (Radio Physics), 4 (Radar), 7 (Engineering) and 8 (Solid State).
