"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.

WSU Computer Comics featured in the April 2012 issue of Wayne State magazine
Under the heading "funny guy" on page 21 of the April 2012 issue of Wayne State magazine you'll find a description of the WSU Computer Comics and its author, Jim Simmons.
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.
8 January 2012
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.
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).
