(The following is excerpted from the EXPLAIN HISTORY command on DCTS.)

In September, 1963, under the direction of mathematics professors John G. Kemeny and Thomas E. Kurtz, a project to establish a time-sharing system at Dartmouth got under way. The fruits of this project were BASIC, a simplified programming language, and a time-sharing system -- using the GE-235 and Datanet-30 computers. This system began operations in May, 1964. In 1965, Dartmouth placed off-campus terminals in secondary schools in the area. At the same time, other computer installations began to use Dartmouth's system software.

Nancy Broadhead provided a tape from 1974, "Reminiscences of DTSS" from Pioneer Day. Several original users/creators describe the system and tell stories. Total length is about one hour. [Part 1] | [Part 2]
These audio files are in MP3 format. Part 1 is about 33 MB, and part 2 is about 12 MB. If you have an MP3 player with streaming capability (Apple's iTunes program is one), then you can "Open Stream" and paste in http://www.dtss.org/remin1974-1.mp3 (or part 2) and it will play over the Internet instead of downloading to your local machine.

Joe Hill found this artifact with Google: "Dartmouth Kiewit System" by The Lone Ranger
This is a 1986 BBS textphile describing the Kiewit network and DTSS from a hacker's standpoint. Contains some foul language.

These are my (Marion) session logs from the first time I ever logged on to DCTS (the later version of DTSS). I had no clue what I was doing. :)
