I think we can say 1967 with high confidence.

Link to the aptly named "MIT AI lab IO bus interface for GE Datanet 760" article.

-Gerald Sussman has preserved a listing of [[Incompatible Timesharing System|ITS]] version 138, most likely from 1967.  It was mentioned in Grant Fjermedal's 1986 book "The Tomorrow Makers".  In 2023, MIT Museum staff began processing the listing, and volunteers transcribed it to machine readable files; at this point there are 25 pages out of more than 120.  The TITLE statement on the first line says "ITS 1.0 3/19/67", but there is reason to believe the date has not been kept current with edits.

 The format of the listing is in the output of some cross reference tool.  Each line is prefixed with a line number and a symbol reference.  The last three pages are a table which lists all symbols and where they are defined.
