 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.

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 was held on November 15th at the Raymond F. Goodrich Preserve. 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).
