DeveloperMIT Lincoln Laboratory
Product familyTX
Release date1958 (1958)

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.[1]


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.[2][3] Because of its powerful capabilities, Ivan Sutherland's revolutionary Sketchpad program was developed for and ran on the TX-2.[4][5] One of its key features was the ability to directly interact with the computer through a graphical display.[6]

The compiler was developed by Lawrence Roberts while he was studying at the MIT Lincoln Laboratory.[7]

Relationship with DEC[edit]

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[edit]

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