Sad news of John Lindley's passing

Subject:         Very sad news
Date:     Wed, 03 Jul 2013 09:26:29 +0100
Dear friends of John,
It is with great sadness that we write to you to inform you of the death of John Lindley [former director of the computer service at Durham University in the days of MTS].  He passed away peacefully after a short illness on Wednesday 26th June. We apologise if we have not managed to contact you before now and that this is the first you have heard, but we as a family are absolutely devastated.
We wish to pass on the arrangements for John's funeral and thanksgiving service which will be held on Friday 12th July and please know that you are all welcome.
There will be a short committal service at 2pm in St. Bede's Chapel, Teesside Crematorium, Acklam Road, Middlesbrough, TS5 7HD.  Following that we will be holding a service of thanksgiving for John's life at 3pm in Nunthorpe Methodist Church, Connaught Road, Nunthorpe, Middlesbrough, TS7 0AN.  After the service please join us for afternoon tea in the church hall.
Traditional black is not necessary.  In lieu of flowers, donations in John's name can be made towards a charity to be decided in due course.  If you wish to donate this can be done at church or direct to Hilda House, Funeral Directors, Dalby Way, Parkway Centre, Coulby Newham, Middlesbrough, TS8 0TW.  (01642 596600)
With best wishes,
Beryl, Bridget and Sarah.

MTS running on a Raspberry Pi

Richard Chycoski from SFU in the now somewhat distant past has MTS running under Hercules under Linux on a Raspberry Pi.  The MTS Today item in the discussion section of the website has details and photographs.

"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.

All 12 issues of the comics as well as a short introduction and a key to the names used are available in the documents section of this web site.

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.

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.

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).
