Colossal Typewriter
Colossal Typewriter by John McCarthy and Roland Silver was one of the earliest computer text editors. The program ran on the PDP-1 at Bolt, Beranek and Newman by December 1960.
About this time, both authors were associated with the Massachusetts Institute of Technology, but it is unclear whether the editor ran on the TX-0 on loan to MIT from Lincoln Laboratory or on the PDP-1 donated to MIT in 1961 by Digital Equipment Corporation. A "Colossal Typewriter Program" is in the BBN Program Library, and, under the same name, in the DECUS Program Library as BBN- 6.
