London Stock Exchange ordered to sell its stake in MTS

The European Commission ordered the London Stock Exchange (LSE) to sell its 60% stake in MTS. However, the LSE said the request was "disproportionate". It warned investors it would struggle to sell MTS and that such a sale would harm its ongoing business. MTS is a relatively small part of LSE's business, but it is a major platform for trading European government bonds, particularly in Italy, where it is classified as a "systemically important regulated business". See BBC News for details.

Bell Canada announced last week it would buy MTS in offer that valued company at $3.9B

Doug Wade sent a URL and a note saying "I find this amusing". Here is the URL to the article: 
    http://www.cbc.ca/news/business/bce-bell-manitoba-telecom-competition-bureau-1.3575496.

Others seemed to find the headlines amusing too, see:
    https://www.facebook.com/douglas.wade.7505/posts/10153783842894234.

But important questions were raised, "Will my MTS service cost more under Bell?"

Try MTS: Exploring the Michigan Terminal System

Try MTS is a very nice, well done, independent web site, created by Rupert Lane in June 2014. It provides information about installing and running MTS under Hercules and an introduction to using MTS. Since 2014 Lane has continued to update the site with the addition of introductions to eleven (so far) of the programing languages available in the D6.0A version of MTS: BASIC, FORTRAN, MAD (GOM), ALGOL 60, ALGOL W, LISP, UTILISP, PL/1(F), SNOBOL, RATFOR, and FLECS. The most recent updates were made in early 2016.

MTS Workshop Proceedings

In May 2014 Don Boettner made his hardcopy collection of proceedings from the 18 workshops held from 1974 to 1993 available. By late June 2014 scanned and OCRed versions of the table of contents materials (schedules, list of papers, list of attendees) were available online as PDFs for viewing or download. And earlier today scanned and OCRed versions for all 18 of the full proceedings (papers and session summaries) were completed and made available online (roughly 13,700 pages in all). Links to the PDFs are available from the "Documents section" of the MTS Archive site (this site). The physical paper copies are destined for the U-M's Bentley Historical Library. I would like to thank Don for saving the proceedings and for making them available.

Don also had a copy of Kari Gluski's trip report for the Community Workshop held in 1994 in Edinburgh. 1994 was the last year a workshop was held. We don't have proceedings for the 1994 workshop and we aren't entirely sure that proceedings were produced. If anyone remembers more details about the 1994 workshop or has a copy of any proceedings, please let us know by sending a note to mts-comments@umich.edu.

I hope to gather more information about the "western workshops" and include that in the MTS Arcive site. I'd welcome any materials or recollections that people may have about these workshops.

I also hope to produce a combined index to the papers and session summaries for all of the workshops, but I'm not sure how long that will take to complete.

There is an MTS Workshops item in the discussion section of this web site that is being used to gather information about the workshops.

Kanags (Chelva Kanaganayakam)

Ralph Sayle posted the following on Facebook:

For my old Computing Centre friends.

You may remember Kanags, a member of the Documentation Group in the mid 1980s. As I recall, he had recently graduated from UBC with a PhD in English, but left for Toronto within a couple of years.

My gawd but that was nearly 30 years so when I saw the obituary in today's Globe it took me a while to recognise Kanags, but Jon Nightingale later verified it was him.

As you can see Sri Lankans have lengthy names, but it was Kanags who suggested we call him by his shortened surname.

Too young to go, especially with such an exemplary career.

Chelva Kanaganayakam: A 'shining beacon' for Tamil literature – Sri Lankan scholar was 'a leader in the development of postcolonial theory and South Asian studies' at the University of Toronto. –The Globe and Mail (Toronto), 26 December 2014.

Suzanne Goodrich 

Suzanne D. Goodrich (Suzy) was born November 9, 1938 and passed away October 1, 2014 in Ann Arbor. She was preceded in death by her husband Raymond F. Goodrich, her sister Marie D. Bearden, and her brother Joseph Dinga. She is survived by her children; Andrew, Thomas (Colleen), and Barbara Goodrich, her granddaughter, Elizabeth Goodrich, and her sister's husband Bill Bearden, his children, grandchildren and great-grandchildren. She loved Ann Arbor deeply and started planning for the Art Fair and Summerfest months in advance. An advocate for environmental causes, she founded the Raymond F. Goodrich Preserve.

Suzanne held both undergraduate and graduate degrees in Mathematics from the University of Michigan, and contributed both time and resources to further the University's work. She was a computer analyst and served as research mathematician at Conductron Corporation, performing radar cross-section analysis, as a Research Associate at the University of Michigan's High Altitude Engineering Laboratory, and on the ARPA sponsored Conversational Use of Computers (CONCOMP) Project at U-M, where she was responsible for developing IBM System/360 symbol manipulation programs and for modifying the multiprogramming system (RAMP) to permit the use of these programs on the PDP-338 remote display terminal. In 1971 she began work at the U-M's academic Computing Center maintaining the FORTRAN I/O routines, working on a new FORTRAN User's Guide, and maintaining the display file routines for the PDP-8/338. She retired from the University of Delaware in 1997.

A combination dedication and memorial service will be held on November 15th at 1:00 PM at the Raymond F. Goodrich Preserve. The preserve access point is located on the west side of North Dixboro Road in Ann Arbor Township, approximately 0.2 miles south of M-14 and 150 feet north of Overbrook Drive (map). In lieu of flowers, contributions in Suzanne's memory can be made to the Washtenaw County Natural Areas Preservation Program.

A biographical sketch for Suzy is available in the People section of this web site.

Lincoln Manual 78: Lincoln Laboratory Multi-Programming Supervisor

Alan Davis (UQV) recently sent me several manuals related to MTS. One of which I had never heard of or seen. It was:

Lincoln Laboratory Multi-Programming Supervisor
Lincoln Manual 78 (ESD-TR-67-14)
by Frank Belvin and Joel M. Winett,
6 January 1967, 255 pages.

The MTS supervisor, UMMPS, was initially developed based upon the MIT Lincoln Laboratory Multi-Programming Supervisor (LLMPS).

The manual was scanned and added to the MTS Archive. And once I knew what to look for I found other copies online at Bitsavers and the Defense Technical Information Center (DTIC).

There is a short conversation about LLMPS in the discussion section of the MTS Archive (this site).

MTS Workshop Proceedings

Don Boettner recently made his collection of proceedings from the 19 workshops held from 1974 to 1994 available for scanning. So far we've been able to scan the table of contents materials (schedules, list of papers, list of attendees) from all of the workshops. They are available in the "Documents section" of the MTS Archive site (this site). We hope to get the full proceedings scanned as well. Once that is done, the physical paper copies are destined for the U-M's Bentley Historical Library. We would like to thank Don for saving the proceedings and being willing to make them available.

Ron Srodawa

Ron Srodawa passed away on January 1, 2014

Ron died of complications of Alzheimer's disease. Ron's obituary is available here. The Srodawa Family would like memorials to be sent to the Alzheimer’s Foundation, Southfield, Michigan, in lieu of flowers, at http://www.alz.org/. Condolences may be sent to apseyfuneralhome.net. His family plans to honor Ronald’s life with a memorial service at a later date.

Ron earned his Bachelor of Science degree (Magna cum Laude, 1965) from the University of Detroit, a Master of Arts degree from The University of Michigan (Mathematics, 1966) and a Doctor of Philosophy in Computer and Communications Sciences from the University of Michigan in 1972. At the University of Michigan he was involved in the early days of the development of the Michigan Terminal System. He wrote the MTS loader (UMLOAD), which Mike Alexander remembers as remarkable because it (i) fit in one page of memory and (ii) was location independent, you could put it anywhere and call it and it would work, there was nothing in it that had to be relocated when it was moved to a new location. He also worked on the development of the MAD/I compiler as part of the ARPA funded CONCOMP project at U-M.

He was appointed an instructor at Wayne State University in 1971 (while completing his doctorate) in Mathematics, later becoming an Assistant Professor and playing a critical role in building the department by serving as acting Department Chair. He moved to Oakland University as Associate Professor of Engineering and Computer Science in 1982. His professional life included academic research, teaching bachelor, and doctoral students and consulting for Ford Motor Company.

A video oral history interview with Jim Henriksen

Jim Henriksen worked at the U-M Computing Center in the late 1960s and early to middle 1970s. He is the president of Wolverine Software, which he founded in January 1976. In 2013 an interview with Jim was included as one of the initial video oral histories of computer simulation pioneers funded by the National Science Foundation (NSF) at the Computer Simulation Archive of the North Carolina State University Libraries. In the first part of his individual interview Jim describes what it was like to work at the U-M Computing Center in the late 1960s and early 1970s.

The link to the Computer Simulation Archive is http://d.lib.ncsu.edu/computer-simulation/ and the link to Jim's interview is http://d.lib.ncsu.edu/computer-simulation/videos/james-o-henriksen-interviewed-by-richard-e-nance-henriksen. The interview is an hour and 10 minutes in length and includes two discussions of the U-M Computing Center from 4:55 to 10:11 and from 58:06 to 1:00:26 (the rest of the interview is interesting too).

There is a short bio-sketch for Jim in the People section of the MTS Archive.

"The Paging Game": Learn or relearn that everything you read on the Internet isn't entirely true

If you do an Internet search for "Paging Game Thing King Zarking" you'll get over 200 hits. Many of them will tell you that the humorous "Paging Game" article was written by Jeff Berryman while he was working on MIT's Project MAC. But Jeff worked at the University of British Columbia when he wrote the article. Neither he nor his article were associated with Project MAC or MIT.

Read the details in the Discussion and the Myths and misconception sections.

"The Paging Game" article itself is reprinted and available online starting on page 2 of the 19 June 1974 issue of the U-M Computing Center Newsletter (Vol.4/No.7) in the Hathi Trust Digital Library.


An HTML version of the 1974 article is also available from the MTS Archive and from Wikisource.

MTS D6.0A - A pre-built version of MTS for use with the Hercules S/370 emulator


A new version of MTS, D6.0A, is now available for download. It is based on the D6.0 version of MTS  from 1988 with various fixes and updates to make operation under Hercules in 2012 smoother. D6.0A is delivered as a simulated 3380 disk drive which eliminates the need to restore MTS to disk from simulated magnetic tapes. There is a README-D6.0A.txt file with a description of the materials included, step-by-step instructions for running MTS under Hercules, a set of Frequently Asked Questions (FAQ) and answers, and a template Hercules configuration file (hercules.cnf). The README-D6.0A.txt file and the d6.0A.zip archive are available from the MTS Archive.

MTS D6.0 from 1988 running under the Hercules S/370 emulator


On 24 December 2011, just 38 hours after the MTS distribution materials became available from Bitsavers.org, MTS D6.0 had been restored from simulated tape and was running under the open source Hercules System/370 Emulator. See the "MTS Today" discussion for details.


8 January 2012

MTS source and object is also available from U-M's Deep Blue Digital Archive


The MTS distributions starting with D1.0 (1968) and ending with D6.0 (1988) are now available from the U-M Deep Blue Digital Archive.  The material is the same as that available from Bitsavers.org, but packaged somewhat differently. Both archives include collections of simulated magnetic tapes in AWS format together with associated documentation. An overview of the material is also available.


22 December 2011

MTS source and object is available at Bitsavers.org


The MTS distributions starting with D1.0 (1968) and ending with D6.0 (1988) are now available in the Software Archive at Bitsavers.org.  The material is available as a collection of simulated magnetic tapes in AWS format together with associated documentation. An overview of the material is also available.

Working with the D6.0 distribution materials it would be possible to create an IPLable version of MTS, but in the future we hope to make this easier by adding an IPLable version of MTS suitable for use with a S/370 emulator such as Hercules. The IPLable version of MTS will be based upon the version of MTS that was in use at the University of Michigan in 1996 shortly before MTS was shutdown.

In a letter dated 20 July 2011 the University of Michigan gave its support and permission to make the MTS distribution materials and an IPLable version of MTS available to the public under the Creative Commons Attribution 3.0 Unported License (CC BY).



24 November 2011

All 12 issues of the WSU Computer Comics are now available


Jim Simmons, writer and artist, has made clean copies of the WSU Computer Comics available for scanning. All 12 issues as well as a short introduction and a key to the names used are available in a sub-folder of the documents and files section







12 August 2011

MTS source and object to become available to the public



In a letter dated 20 July 2011 the University of Michigan gave its support and permission to a project to make the MTS distribution materials and an IPLable version of MTS available to the public under the Creative Commons Attribution 3.0 Unported License (CC BY). The MTS distributions starting with D1.0 (1968) and ending with D6.0 (1988) will be made available as a collection of simulated magnetic tapes in AWS format and should be available in a few weeks.  The IPLable version of MTS will take a little longer and will represent the version of MTS that was running at the University of Michigan in 1996.

Additions to the NUMAC, UQV, and WSU stories


Ewan Page and Denis Russell have added to the story of the early days of MTS at NUMAC.

Dale Bent and Gerry Gabel, with some help from John Stasiuk, have filled in most of the details about how MTS came to the University of Alberta.

While we would be happy to receive more stories, with the recent additions we now have a pretty complete description about how MTS came to most of the MTS sties.  The main exception is Wayne State. And there Jim Simmons was kind enough to share "A Brief History of Computing at Wayne State University (1947 to 1979)", a booklet by Robert Monroe, an Associate Director at WSU's Computing Services Center.

The octothorpe and "one of the great comeback stories in the history of competitive punctuation"


John Hogg passed along the following item:

"What we have here is one of the great comeback stories in the history of competitive punctuation" according to Robert Fulford writing about the octothorpe in a column in the opinion section of the National Post on 30 November 2010.

Since # is the MTS Command Prefix character, the MTS Community has a special fondness for the octothorpe (or pound-sign, number-sign, hash, sharp, ...) and I [Jeff] am happy to see it making a comeback.

For more on the octothorpe.
