DTSS(Dartmouth Time-Sharing System, Dartmouth time sharing system) are large-scale time sharing systems implemented for the first time in the world by the success back. I am affected by a time sharing system built on PDP-1 in Bolt, Beranek and Newman. In 1962, John ケメニー and Thomas Kurtz () of Dartmouth College applied to NSF for financial support of the new time sharing system development (as for having been really invested 1964); [1]. Implementation was started under ケメニー and conduct of Kurtz by the team [3] of the student for the purpose of offering the easy access to calculation facilities to all members of the university in 1963 [2]. A system applied it at 4:00 a.m. on May 1, 1964 and was started. In addition, this system wants to be managed until the end of 1999 [4]; [5]. DTSS was implemented on GE 235 computer at first and was the form that terminal processor GE Datanet 30 controlled 235. I was implemented again later on GE 635 [1], but used Datanet 30 for terminal control as ever. 635 DTSS realizes the time sharing with a little less than 300 terminals in the 1970s, and this is very large for those days.
DTSS gave priority to usability and, for the purpose (education of the student of every subject), was designed.
The world's first integrated development environment was implemented in DTSS. This was a command-based system, and the following commands were implemented.
- I name NEW - - new program and start programing
- I search the program that I made before OLD - - and take it out
- I display a program as of LIST - -
- I store a program as of SAVE - -
- I execute a program as of RUN - -
Many users took these commands for a part of the Dartmouth BASIC language, but it was really a part of the time sharing system, and these commands were used when I used a program of ALGOL[6] and FORTRAN via DTSS terminal.
The line with the line number is added to a program at the top that a user input and rearranges it if I input the line number same line before. I am compiled immediately, and the other input line is carried out. The input only for line number is not stored, but is effective in deleting it if there is the same line that has been input with line number. What become such an input method is because a terminal used in DTSS was a teletypewriter terminal.
Other schools and research organizations of the East Coast were connected to DTSS from 1968 through the mid-1970s by the network of the dawn, too. For example, in Goddard University (), Philips academy, Naval Academy, I was connected using teletypewriter terminal ASR-33 and a modem. The exchanges of the E-mail-like message were possible, and the real-time chat function that became the forerunner of the talk command of the UNIX existed between users.
A project to play DTSS system on a simulator in 2000 is carried out, and DTSS becomes available on Microsoft Windows and Macintosh [7].
