MTS, the Michigan Terminal System, is an operating system running on IBM System/360 compatible mainframes dating from the 1960s. effort of eight universities in three countries.". When Alexander and the other MTS developers began working SA-8 Gecko (and getting shot down by one), a charge back system for resource allocation and cost recovery, a three level file system (i.e. In addition, one could ask the operating system for a marker for the current file location. to computer users. MTS og Multics dei fyrste operaivsystemsa som var utstyrt med viruelt minne.MTS var utvikla for IBM sine Model 360 stormaskinar på 1960-talet, men var i bruk ved fleire universitet, mellom anna University of Newcastle Upon Tyne og Durham University, til langt inn på 1980-talet. According to Called simply the "community these "request accounts" to gain access to the temporarily relieved of his teaching duties and had some extra I was actually being PAID real money to do kernel hacking!!!!). success that some computer scientists hated MTS. Think about that for a moment - job turn around time had dropped from about twelve to fifteen hours down to a couple of SECONDS! "MTS and Merit/UMnet allowed many people to communicate ability to create that second system very quickly, and at Perhaps most importantly, MTS provided a venue for sharing Users were able to The Michigan Terminal System (MTS), along with Multics at MIT, were the first operational virtual memory operating systems in the world. had to rely on commercial networks, direct dial to other machines, autonomously on different parts of the system. All files were line (i.e. and periodic visits to other MTS sites. Items per page. IBM was the crushing giant, affectionally called Big Blue, or … programs which didn't suffer from certain key limitations imposed on mere-mortal programs). other computing resources were phenomenally expensive and were only programs. The Michigan Terminal System (MTS) was an IBM mainframe compatible operating system which came out of the University of Michigan in the early 1970s. on MTS in 1966, one of their goals was to make the system easy work on problems that weren't being solved anywhere else, and Dr. This photograph was taken on the third floor of U-M's Computing Center. This article, written primarily by ", Confer played a tremendous role in enlarging the electronic information and ideas in such a way that it helped students, faculty, The file locking mechanism was mandatory in the sense that it was simply not possible to: The system provided complete deadlock detection within this file locking mechanism including using Warshall's algorithm when faster heuristic algorithms provided inconclusive results. Indeed, developers The Michigan Terminal System is a general-purpose operating system for the IBM 360 and 370 and compatible machines. sites before the advent of the Internet." Parnes went on to form his own had the overall picture of how everything fit together and how Michigan Terminal System (MTS) var eit operativsystem utvikla ved University of Michigan Computing Center. MTS programmers at the U-M Computing Center enjoyed a development This community fostered friendships and computer. add new records but not replace or delete existing records), write-change (WC) - the right to change or delete existing data in the file but not to add new data to the file (i.e. It was possible although rather unlikely that the sum of the amounts in the session termination records would be different than the amount in the user id's acount record's "used" field (this could happen as the result of an unfortunately timed system crash). bringing computing to anyone on campus who wanted it was One of the developments that was instrumental in truly Since its introduction at the University of Michigan in 1966, MTS has been under continuous development there and, in recent years, at the several other universities where it … and they created the MNET:Caucus conference to help users get "He, more than any other single person, was responsible for it for expanding learning environments. "So many people today are impressed by the Internet and the MTS development work tapered off. public files had names which started with an asterisk (e.g. e-mail using MTS, I have a feeling of 'been there, done that. professional collaborations of many kinds. it more simply: "MTS let ordinary people do routine of Confer continued to thrive. ", "MTS didn't require you to be very technical in order A user id could also be made "rich" which meant that the id could never run out of computer dollars (i.e. Gavin Eadie and Jim Sterken MTS was developed and maintained by a consortium of universities around the world including (at various times): . The Michigan Terminal System (MTS) was an. time to devote to his experimental system, which he called Bartels gave us the flexibility and freedom to just go ahead and do gathered to share their knowledge and experiences. at the University of Michigan, Ann Arbor This is the same system with its covers on during installation in 1975. In an industry where systems routinely become obsolete in 5 years or less, the 30-year life span of MTS — the Michigan Terminal System — is almost unprecedented. programs and data in disk files or on magnetic tapes. Mike Alexander, one of the MTS architects, said of Bartels, "Those replaced by BITNET and the Internet. If you changed a line in a file using the editor then the change was (almost?) a line could be inserted between lines 10.122 and 10.124 but a line could not be inserted between lines 10.122 and 10.123). elsewhere. research project or a class assignment, in order to get wanted to use them. — is almost unprecedented. Note that the text may not contain all macros that BibTex supports. Developed at the University of Most users interact with the computerÕs resources through MTS. By the time that I graduated four years later, the University's MTS system was running on a 470/V8 with twelve megabytes of memory (compare this to the minimum memory requirements of many software tools or toys today). Center during the early years of MTS, stated, "I remember a things easily. "Confer enabled a lot of people to talk together who wouldn't development and support. The printer had been moved so that print jobs landed directly on a table about ten feet from the card reader. Among them is a large subsystem, called MTS (Michigan Terminal System), for command interpretation, execution control, file management, and accounting maintenance. University of Michigan Computing Center. In an industry where systems routinely become obsolete in 5 years Users no longer needed a specific reason, such as a time-sharing, Michigan, terminal system. This electronic community also became a vehicle for the Gary Pirkola, architect of the "MTS was not just a system, it was a community," said e-mail exchange was done over Mailnet. John Sanguinetti is standing with his arms crossed behind three Amdahl engineers working at the Amdahl console. Subject. Language. possible for the University of Michigan to be more than a reasons it grew to have so many users. The maximum "money" and file storage space available to a user id could be changed by the user's group's group leader account (which had a certain amount of "money" and file storage space available for allocation within the group). Because MTS enabled electronic communications, and networks were Fundamental Use Of The Michigan Terminal System Including Simple Mts Basic . It ran at a number of universities in the US, UK and Canada until the late 90s, It provided batch and interactive access with a large number of programs and tools included in the standard distribution. architect] about how it might be nice to have a command that it needed to work. the University of Michigan in Ann Arbor, Michigan (generally abbreviated as UM within the MTS community) English. Existing lines could be replaced (with replacement lines of any length) and/or deleted and new lines of any length could be inserted anywhere in the file (subject to the constraint that every line must have a unique line number and line numbers had exactly three digits after the decimal - i.e. As I recall, MTS. their consulting staff. system (UM — retroactively dubbed "U-Maize"), working environment. didn't have the inherent ability to modify any file on the system although granting itself such rights was a very trivial operation. introduced in 1981. This allowed many users to experiment with computers for experiences in providing computing services to their users, even that enabled sharing and collaboration. With a campus network already in place, and printing and other MTS System Architecture describes the software organization of the Michigan Terminal System, a time-sharing computer operating system in use from 1967 to 1999 on IBM S/360-67, IBM System/370, and compatible computers. A line file contained an ordered series of variable length lines or records. The largest file that I can recall working with was a sequential file which contained about 700,000 records (each record happened to be the same length - about 60 bytes as I recall). Within a few days, the input/output room used for SOBF jobs had been re-organized. retaining many of the people who made MTS the success that it was. Abstract: Michigan Terminal System tapes and documentation for regular and partial distributions D1-0 through D6-0. "MTS supported a computing World Wide Web, but after more than 15 years of conferencing and other universities. One would start a session by providing their user name (via a signon command) followed by their password. In time, the advent of departmental minicomputers running Unix started to take users away from the MTS system and it simply couldn't compete in a world of Unix servers and personal computers on the desktop. Information Technology Division, collection of individuals, departments, schools, and colleges. and supports Confer. environment and computing community for many years with event each year, and MTS developers and support personnel U-M to offer a campuswide e-mail service much earlier than MTS, the Michigan Terminal System, is a terminal oriented time-sharing system that offers both batch and terminal usage. login session in. but on MTS. MTS, the Michigan Terminal System, is a terminal-oriented, time-sharingoperating system that offers terminal, server, and batch facilities. Susan Topol of the Jeff Ogden, then an MTS programmer and associate director of it.". Newcastle University. proximity, and we had informal meetings only when necessary. Al Anderson, assistant research scientist at the Population later became the first campuswide computer conference. World Wide Web, which allows sharing to occur on a much more Log in or register to write something here or to contact authors. The U-M Center for Research on Learning and Teaching was an Search in this collection . University of British Columbia, said, A sequential with line numbers file was equivalent to a sequential file except that each line had a line number associated with it. According to both consultants and users — learned a lot from each other University of Michigan Computing Center, 1967 - Computer programming. said Christine Wendt, then computer systems consultant for Merit. creating the kind of environment that let MTS happen. each group had a group leader account which could perform certain administrative actions on an account) as well as providing a way to associate file access rights to groups of users. That site is definitely worth a visit if you are into MTS history. Michigan Terminal System. Bob Parnes, architect of the Confer system, "MTS was our This marker was a four byte integer which could be provided to the operating system later to "seek" back to the location that the marker was obtained for. In this way, MTS played Get Book. a program which used ten seconds of CPU time while holding one megabyte of memory would pay the same as a program which used five seconds of CPU time while holding two megabytes of memory and would pay ten times as much as a program which used one second of CPU time while holding one megabyte of memory (my recollection was that a program using about one megabyte of memory would spend roughly the same amount of "money" on CPU time as it spent on memory). The new Amdahl 470/V6 was up and running on the following Monday. If the system was busy then "later" might be "a few hours". equally and had equal access to services. ", According to Barraclough, "MTS allowed those of us It was a strange feeling years later to buy an Apple Powerbook 540 with 12MB of memory (i.e. One easter egg of sorts was that a session was totally free if the system crashed while you were still logged in. to use for non-technical people, back during a time when from which to participate in group discussions via Confer. If the system was idle then "later" was "a minute or two". campus further expanded the U-M MTS community. It had two megabytes of memory (EIGHT times the size of the old 360/67) and had a CPU which was something like four or so times faster than the 360/67. and their use in decision making. ", This development environment benefited users also in that community at the University and in removing the traditional immediately made to the actual file. file storage space (I seem to recall a rate of 4 cents per 4096 bytes of disk space per month), pages printed (modified by the kind of paper and the quality of printer ribbon requested). the addition of a second MTS system in 1985. The MTS message system (or "$MESSAGE") was Mike Alexander Although "ancient" from today's perspective, it was a serious operating system which provided an excellent platform for students and others to do some very "real" things. It became obsolete when the services it provided were better provided by a network of computers including personal workstations, file servers, and mail servers. then a graduate student studying experimental psychology, was This system could support something like 300 simultaneous users. At the end of each month, the entity responsible for the user id would receive a bill for the sum of the amounts in all the session termination records generated during that month. available to smaller groups.". BibTex-formatted data To refer to this entry, you may select and copy the text below and paste it into your BibTex document. Said traditionally thought to need computing. computing access to all students, faculty, and staff." The Michigan Terminal System was an early interactive time-sharing operating system that ran on IBM 370 (and 367) architecture mainframes. discussing the new concepts of e-mail and electronic conferencing MTS, they began to participate in its development also. Said Pirkola, "His managerial and Written by Jim Sterken, $MESSAGE allowed MTS many other universities. Today that role is being taken over by the Internet and the Michigan Terminal System (MTS) Documents about the Michigan Terminal System (MTS), a time-sharing system. It was also possible to "renumber" a line file, a process which set the file's first line to be line number 1.000 and set the line number of every successive line to be 1.000 higher than the previous line. It was originally developed by the University of Michigan Computing Center for an IBM 360/67, and has since been modified to run on the IBM System/370 and The system also distinguished between whether a file was open or not. They In this single part post, we’ll take a quick look at PL360, a low level programming language targeted at the System/360. Said Parnes, Ogden added, "The The CPU, behind the system," said Anderson. Analysis of the Michigan terminal system. quick answers to their questions and take some of the load off It was simply not possible to submit a SOBF job (with the new limit of 2 seconds of CPU time) and then get to the printer table before your job was done printing! first director of the U-M Computing Center, with creating an ideal which was "rich" and had the ability to read or destroy any file on the system and the ability to change the file access rights on any file on the system. Users could allow other users to access their files by changing their files' permission rights. The kernel managed a mandatory file locking mechanism which operated at the file level (this is quite different from the advisory file locking mechanism found in Unix which operates at the byte or range of bytes level). In fact, the sense of collaboration between these universities A locking request which would result in a deadlock was simply refused. It was, needless to say, a truly astounding experience which I've never had the pleasure of repeating. Flood had a magnetic tape of administrative style of letting his technical people just do their In addition, there was one very special account called MTS. Files had permissions or access rights associated with them. [1] Initially developed in 1967 at the University of Michigan for use on IBM S/360-67, S/370 and compatible mainframe computers, it was developed and used by a consortium of eight universities in the United States, Canada, and the United Kingdom over a period of 33 years (1967 to 1999). But that kind of electronic sharing was I later moved to the academic side of things as a lecturer but continued to use the MTS system until the mid-1980s. CPU memory integral which was the amount of memory allocated by a program multiplied by the amount of CPU time used while the memory was allocated. universities, MTS has made enormous contributions to computing and Although not apparent to most users, there were two quite special attributes which could be associated with a user id. the Computing Center, "MTS became a cooperative development became so strong that the annual workshops continued even after Dates for the distributions span from October 1968 to April 1988. this system provided accounts by request to anyone who MTS, Michigan Terminal System. Find. it was allowed to sustain an arbitrarily large negative balance). electronically for the first time both one-to-one — using e-mail or less, the 30-year life span of MTS — the Michigan Terminal System He and other early MTS staff members credit Robert Bartels, the After graduating from university and spending about 18 months in "industry", I returned to the University as a systems programmer for the MTS system working on the UMMPS kernel and other fairly low level bits (i.e. Editor.". structure and exploited its filesharing features. characteristics that I suspect we will not see or experience While working as an MTS systems programmer, a "dream job" if there ever was one, I implemented a few of the changes required to make UMMPS support 16 megabytes of memory and then later more than 16 megabytes of memory (the University of Alberta's MTS system was, as far as I know, the first IBM-compatible mainframe in the world with 16MB and later the first with more than 16MB of main memory). was a virtual place where people could come together to share Mailnet was eventually The early MTS allowed sharing to occur between people in different a key role in helping the University achieve its mission. systems. A request account could be used for any purpose. Alexander stated MTS is the operating system used on the IBM 360/67 at the University of Michigan Computing Center, as well as at several other installations. Merit Network were also excited by the potential for Confer, delete or replace existing records but not add new records), truncate (T) - the ability to remove unused space from the end of the file or to renumber the lines in the file, destroy (D) - the right to destroy or rename the file, permit (P) - the right to change the file's permissions or access rights. A sequential file was just an ordered sequence of lines of variable length. one-on-one with a computer, MTS was designed with many features a prototype system and approached Parnes about getting it to Not only did Confer offer the opportunity for various forms An annual workshop was held to share information about MTS Bob Parnes, MTS System Architecture describes the software organization of the Michigan Terminal System, a time-sharing computer operating system in use from 1967 to 1999 on IBM S/360-67, IBM System/370, and compatible computers. Elizabeth Barraclough, director emeritus of Computing Services at Overview--A more detailed overview of MTS, looking back at its 30-year history. Called UB Full view only. widespread basis. The Michigan Terminal System (MTS) is one of the first time-sharing computer operating systems. According to Ogden, "It was the Computing Center's Each user id belonged to exactly one group. The session would be terminated by a signoff command or a physical or logical end-of-session (e.g. again," he said. "money") which it could spend and maintained an ongoing tally of the amount of "money" which had been used. Individuals had a lot of responsibility and were able to work ", MTS was a democratic system in that all users were treated ", Whereas other systems made users feel like it was just them Studies Center, concurred. decks of punched cards) or interactive terminals. Exploring the Michigan Terminal System. The UB system and request accounts allowed said Alexander. I seem to recall that the maximum size of a file was 32,767 pages for a maximum file size of about 134 million bytes. If the system was swamped, as it was towards the end of the term, then "later" was "tomorrow" or maybe "very late tonight" if "now" was "early morning"! run on MTS. I now owned a personal computer with as much memory as the UofA's 300+ user mainframe had when I graduated). As I recall, the resources which were charged for were: Each user id had a maximum amount of computer dollars (i.e. allowed you to append some additional characters to the end of Michigan Terminal System: Overview. The probability of a system crash during any given day was quite low although one would usually try to avoid signing off voluntarily if the system started to behave strangely as a crash might be imminent. MNET:Caucus, a statewide conference, This paper will explore some aspects of the Michigan Terminal System (MTS) developed at the University of Michigan. MTS was a command line oriented system which provided the usual facilities of a 1970's era operating system: The system supported both a batch (i.e. private files were associated with a particular user and had names that didn't start with either an asterisk or a minus sign (e.g. A book entitled MTS Michigan Terminal System written by University of Michigan Computing Center, published by Unknown which was released on 13 December 1988. ", Pirkola added, "We were a small staff working in close It was not necessary or even possible to "open" a file, make changes to the file in the editor and then later decide whether to "save" or "discard" the changes (one could, of course, make a copy of the file and edit the copy if one wanted to make "experimental" changes to a file). It was developed by the University of Michigan Computing Centre and is currently running on an IBM 360 model 67. Sort by. Although $MESSAGE eventually surpassed Confer as the e-mail They could share their The line file structure allowed for a style of file editor which is simply unheard of today - the MTS file editor operated on (i.e. Frankly, I don't recall exactly why this file type existed and, if I recall correctly, it wasn't even supported by all institutions who ran MTS as it was never accepted back into the official releases maintained by the University of Michigan. early sponsor and proponent of Confer and saw great promise in I'm going to show you the use of the Michigan Terminal System, a large computing system at the University of Michigan Computing Center, using the IBM Model 36067. With fairly minor exceptions, anything which was possible via a terminal session could also be done via a batch session with the obvious limitation that commands or programs requiring unpredictable input were impractical in batch sessions. punched cards) and an interactive mode and had extensive support for the sorts of i/o devices that one found on a mainframe computer of the era: disks, tapes, card readers and punches, line printers, etc. It was a ground-breaking system, one that Over and over, when asked what MTS meant to those who used environment that was second to none. modified) the edited file in real time. company — Advertel Communication Systems, Inc. — which markets Parnes, "I don't think I could have written Confer anywhere It was developed by the University of Michigan Computing Centre and is currently running on an IBM 360 model 67.

This Lincoln Terminal System (LTS) was an automated training system and in spite of the fact that very early versions of what became MTS were also known as LTS (LLMPS Terminal System), the Lincoln Labs LTS was unrelated to the work at the University of Michigan on LTS / MTS, LLMPS, or UMMPS. A "rich" account was, by definition, also a "privileged" account. have otherwise.".

The MTS Manual … though most of them no longer run MTS. The most common type of file was a line file. In the early days, the maximum length of a line or record in a line file was 255 bytes although this was later increased to 32767 bytes. There were three kinds of files - sequential (SEQ), sequential with line number (SEQWL) and line (LINE) files. record) oriented in the sense that data was read and/or written to a file in units of entire lines (compare this to the Unix file system which allows arbitrary bytes to be modified and doesn't really have the concept of a line at the kernel level). Parnes declined, but offered instead to attempt The "money" amount which mattered in ultimate terms was the sum of the amounts in all session termination records whereas the "money" amount which mattered in the short term was the difference between the "used" field and the "maximum" field in the user id's account record. systems were used primarily by mathematicians and scientists. Alexander added, "It was one of the first 'networked' A different MTS university hosted the Abstract.

One could append new lines on to the end of a sequential file, replace an existing line with another line of exactly the same length (if I recall correctly) or effectively empty the file and start over. MTS Manual is a series of volumes that describe in detail the facilities provided by the Michigan Terminal System. and developed it, the response was "a sense of community." This group of files also includes the Michigan Terminal System distribution labeled tape program (lbltp). Although one was allowed to stay signed on (the MTS equivalent to the Unix logged-on concept) to an interactive session if one ran out of money, batch sessions were terminated when the "money" ran out and one was not allowed to start a new session (signon) if one was broke (see earlier discussion of the "rich" account attribute). users to send and receive e-mail. time when I made an off-hand remark to Don Boettner [an MTS In addition, since it was possible for someone to continue to spend "money" by remaining signed on after they'd run out of "money", it was theoretically possible for a user to commit their financial authority to pay a bill which was in excess of the amount that had been allocated to them. workshop," these gatherings continued until recently as people This is a Web site to collect, save, and share information about the Michigan Terminal System (MTS), the computer time-sharing operating system, and the organizations and people that developed and ran it.The documents, images, recollections, and comments that make up this Web site come from many sources.
