	Wikipedia: CTSS
		CTSS was first published, as well as operated in a time-sharing environment, in 1961; in addition, it was the system with the first computerized text formatting utility, and one of the very first to have inter-user electronic mail.
		Although CTSS was not an influential operating system in its technical detail, it was very influential in showing that time-sharing was viable, in the new applications for computers which were first instantiated there, and because of its successor, Multics, which all modern operating systems are intellectually descended from.
		ITS, the Incompatible Timesharing System, another early, revolutionary, and influential MIT time-sharing system, was produced by people who disagreed with the direction taken by Multics; the name was a hack on CTSS, as the name of Unix was later a hack on Multics

	Incompatible Timesharing System - Wikipedia, the free encyclopedia
		ITS development was initiated in the late 1960s by those (the majority of the MIT AI Lab at that point in time) who disagreed with the direction taken by Project MAC's Multics project (which had started in the mid 1960s), particularly such decisions as the inclusion of powerful system security.
		The name was chosen by Tom Knight as a hack on the earliest MIT time-sharing operating system, the Compatible Time-Sharing System, which dated from the early 1960s.
		Among other significant and influential software subsystems which were developed on ITS, the Macsyma symbolic algebra system is probably the most important; the GNU INFO help system, MacLisp (the precursor of EmacsLisp and CommonLisp), and EMACS was also started on ITS.

	Re:[freenet-chat] DMCA/SSSCA/Software Patents from 1950
		Still, they had to live with timesharing systems, so they did what any good hackers do: Write their own timesharing software.
		While they still didn't like the very idea of timesharing, at least they could make a system that was imbibed with the hacker spirit.
		A timesharing system is practicly an operating system; if you're playing around with hardware at that low of a level, then you most likely can disable any "copyright controls" the manufactures have put in.

	TOPS-20 - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-11-06)
		The TOPS-20 operating system by DEC - the second proprietary OS for the PDP-10 - preferred by most PDP-10 hackers over TOPS-10 (that is, by those who were not ITS or WAITS partisans).
		By the early 1970s, almost all of the systems on the ARPANET ran TENEX.
		When the name SNARK became known, the name was briefly reversed to become KRANS; this was quickly abandoned when someone objected that "krans" meant "funeral wreath" in Swedish (though some Swedish speakers have since said it means simply "wreath"; this part of the story may be apocryphal).

		It had the SM command for positing the message and a part that could wait for the message in the background in a users process by taking advantage of the same facility used for saying "New Mail".
		ITS (Incompatible Timesharing System) on the PDP-10 had a way to link console in various ways so that would also provide a talk facility.
		I would credit the 940 as having been a key source of the concepts since it was developed in 1964 and onward and flexible teletype handling was an essential element.

	About the GNU Project - GNU Project - Free Software Foundation (FSF)
		The AI Lab used a timesharing operating system called ITS (the Incompatible Timesharing System) that the lab's staff hackers (1) had designed and written in assembler language for the Digital PDP-10, one of the large computers of the era.
		But it probably also delayed completion of a minimal working system by several years, as GNU developers' time was put into maintaining these ports and adding features to the existing components, rather than moving on to write one missing component after another.
		She, a Unix system administrator, had pointed out how her name would fit a common naming pattern for Unix system versions; as a joke, she told her friends, "Someone should name a kernel after me." I said nothing, but decided to surprise her with a kernel named Alix.

		ITS development was initiated by those who disagreed with the direction taken by MIT's Project MAC's CTSS (which was the majority of the AI Lab in the 60s), particularly such decisions as the inclusion of rigid system security.
		ITS was initially developed for the Digital Equipment Corporation PDP-6 computer, and later for the PDP-10 where the it saw the majority of it's use and development.
		The GNU INFO help system used in Linux, some versions of UNIX, and EMACS was started on ITS.

		As the GNU project proceeded, and increasing numbers of system components were found or developed, eventually it became useful to make a list of the remaining gaps.
		One system is an exception to this: on the GNU system (and this includes GNU/Linux), the GNU C library is the only C library.

	Mob Software
		For every major operating system, there are people who absolutely demand and rationally require the newest backwardly incompatible features, and others who absolutely and rationally require the oldest features to remain as they are forever.
		Even though the designers of this system didn’t think of it this way, this is a clearly biological approach to the problem: a swarm of small repair agents fixing up code on the fly to make it work when the context of its operation has changed.
		The system can be described as one of "alternating disequilibrium" where the aim is to never have debts "paid off" but to preserve a situation of personal indebtedness.

	Glossary
		Computer systems typically incorporate capacious storage devices that are slow (e.g., disk drives) and smaller storage devices that are fast (e.g., memory chips, which are 100,000 times faster than disk).
		The operating system is also responsible for hiding the details of the computer hardware from the application programmers, e.g., letting a programmer say "I want to write ABC into a file named XYZ" without the programmer having to know how many disk drives the computer has or what company manufactured those drives.
		An operating system developed by Ken Thompson and Dennis Ritchie at Bell Laboratories in 1969, vaguely inspired by the advanced MULTICS system built by MIT.

	ITS - the Incompatible Timesharing System
		These are some brief notes on setting up an ITS system based on klh10 and the PI (Public ITS) distribution.
		Since the console gets random typeouts from the system (it is intended as a paper console logging what's happening to the system), it's a good idea to use the system over Telnet or Supdup.
		There is very little idle/lost time on an ITS system under klh10 with the host device+patch.

		The Incompatible Timesharing System is perhaps their most significant accomplishment, but very little that has been written about it (and nothing, to my knowledge, by STS people).
		During the same period, there are dozens of reports and publications on the AI lab software the lab created.
		The Lab was trying to differentiate itself from Project MAC, where they were studying how to make a timesharing operating system; the AI Lab people wanted to USE a timesharing operating system and actually get some work done.

		The 940 system definitely had such a mechanism.
		As I recall, the 940 system was quite different from CTSS's; it worked by linking the output channel of two (or more?) ttys so that anything sent to one of them was output to both.

	The GNU Operating System and the Free Software Movement
		The idea that the proprietary software social system -- the system that says you are not allowed to share or change software -- is antisocial, that it is unethical, that it is simply wrong, may come as a surprise to some readers.
		However, some commercial distributors of GNU/Linux systems who were not strict about sticking with free software added KDE to their systems -- producing a system with more capabilities, but less freedom.
		The biggest deficiency in our free operating systems is not in the software -- it is the lack of good free manuals that we can include in our systems.

		Starting this Thanksgiving I am going to write a complete Unix-compatible software system called GNU (for Gnu's Not Unix), and give it away free to everyone who can use it.
		In particular, we plan to have longer filenames, file version numbers, a crashproof file system, filename completion perhaps, terminal-independent display support, and eventually a Lisp-based window system through which several Lisp programs and ordinary Unix programs can share a screen.
		I have worked extensively on compilers, editors, debuggers, command interpreters, the Incompatible Timesharing System and the Lisp Machine operating system.

	ITS - TunesWiki (Site not responding. Last check: 2007-11-06)
		ITS (Incompatible Timesharing System) was a famous OS developed by hackers at MIT's AI lab from 1967 to the early 1980's for the DEC PDP-6 and PDP-10 family.
		It was famous for being the antithesis of MIT's security-obsessed CTSS (Compatible Time-Sharing System), by being very hackable and so user rights were a matter of social respect and ethics alone, rather than the dictates of the system, which often limited performance and capacity of the system.
		Richard Stallman, founder of the GNU project, got the idea of free software from his work with ITS.
