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).
