The MIT Lincoln Laboratory TX-2 computer was the successor to the Lincoln TX-0 and was known for its role in advancing both artificial intelligence and human–computer interaction. Wesley A. Clark was the chief architect of the TX-2.{{cite book |title = Biomedial Computing, Digitizing Life in the United States |author = Joseph November |chapter = The LINC Revolution |page=144 |publisher=The Johns Hopkins University Press |year=2012}}

Specifications

The TX-2 was a transistor-based computer using the then-huge amount of 64K 36-bit words of magnetic-core memory. The TX-2 became operational in 1958.{{Cite book|url=https://books.google.com/books?id=4iU-AQAAIAAJ&q=%22TX-2%22+1958|title=Computers and People|date=1961|publisher=Berkeley Enterprises|pages=312|language=en}}{{Cite book|url=https://books.google.com/books?id=K4YlDwAAQBAJ&dq=%22TX-2%22+1958&pg=PA131|title=The Machine in the Ghost: Digitality and Its Consequences|last=Boast|first=Robin|date=2017-03-15|publisher=Reaktion Books|isbn=9781780237879|pages=131–132|language=en}} Because of its powerful capabilities, Ivan Sutherland's revolutionary Sketchpad program was developed for and ran on the TX-2.Reilly, Edwin D.

Relationship with DEC

Digital Equipment Corporation was a spin-off of the TX-0 and TX-2 projects. The TX-2 Tape System was a block addressable 1/2" tape developed for the TX-2 by Tom Stockebrand which evolved into LINCtape and DECtape.

Role in creating the Internet

Dr. Leonard Kleinrock developed the mathematical theory of packet networks which he successfully simulated on the TX-2 computer at Lincoln Lab.
