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.

Even more MTS related documents are now available online from the Hathi Trust Digital Library

Working to ensure that the
cultural record is preserved and
accessible long into the future
The U-M Information Technology Digest from 1992 to 1998 has been added and the MIDAS and OSIRIS manuals have been switched from "Limited (search-only)" to "full view".

The Hathi Trust is a partnership of major research institutions and libraries that is building a reliable and increasingly comprehensive digital archive of library materials converted from print that is co-owned and managed by a number of academic institutions. The collections of the University of Michigan that have been scanned and are available online include roughly 250 documents related to MTS or to the UM Computing Center.  Most of these documents are "full view", but a few are "search only".

Included are:
  • MTS Volumes 1 to 23
  • Introductory manuals
  • Computing Center memos from 1967-1983
  • Computing Center Newsletters from 1971 to 1986
  • U-M Computing News from 1986 to 1991
  • U-M Information Technology Digest from 1992 to 1998
  • MTS Workshop proceedings from 1974 and 1975 (the 1st and 2nd workshops held at UBC and UQV)
  • Michigan Interactive Data Analysis System (MIDAS) manuals
  • Organized Set of Integrated Routines for Investigations with Statistics (OSIRIS) manuals
  • Digital computing, FORTRAN IV, WATFIV, and MTS (with *FTN and *WATFIV) by Carnahan and Wilkes
  • FORTRAN 77 with MTS and the IBM PC by Carnahan and Wilkes
  • Pre-MTS documents on MAD and the University of Michigan Executive System (UMES)
For a list of the documents, see the public categories: "Computing at Michigan", "Michigan Terminal System (MTS)", "UM Computing Center", "Merit Computer Network", "MIDAS (statistical analysis)", "OSIRIS (statistical analysis)", and "MAD: Michigan Algorithm Decoder".

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 Gable, 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.

New article on CONFER added to Wikipedia

A new article describing the CONFER computer conferencing software developed by Bob Parnes that ran on MTS and Unix is available on Wikipedia. See http://en.wikipedia.org/wiki/CONFER (software).

Still more WSU Computer Comics Added

Jim Simmons, writer and artist, is making clean copies of the WSU Computer Comics available for scanning. There are 12 issues. Nos. 1-8 are now available in a sub-folder of the documents and files section.  More to come.

MTS manuals and documentation at BitSavers.org

BitSavers is an informal project of
the Computer History Museum
In addition to the documentation available in the "Manuals and documentation" section of this web site, as of 11 January 2011 most of the material is also available at BitSavers.org in the directories:
