As mentioned above, Hanover High School was connected to DTSS from the system's beginning. Over the next decade, many other high schools and colleges were connected to DTSS via the Kiewit Network, named for Peter Kiewit, donor of funds for the Kiewit Computation Center that housed the DTSS computers and staff. These schools connected to DTSS via one or more teletypes, modems, and dial-up telephone lines.<ref>{{cite book |author1=Robert Hargraves |author2=Thomas Kurtz |chapter=The Dartmouth Time Sharing Network |title=Computer-Communication Networks |editor1=Norman Abramson |editor1-link=Norman Abramson |editor2=Franklin F.

From 1968 to 1970, Dartmouth added a number of colleges to the Kiewit Network via its Regional College Consortium. They included: [[Bates College]], [[Berkshire Community College]], [[Bowdoin College]], [[Colby–Sawyer College|Colby Junior College]], [[Middlebury College]], [[Mount Holyoke College]], [[New England College]], [[Norwich University]], the [[University of Vermont]], and [[Vermont Technical College]].<ref>{{cite tech report |author=Thomas E.
