MR12.7 has been released. See MR12.7 for information about this new release. Purpose The purpose of this wiki is to provide information to users wishing to run Multics under the DPS8M simulator. While other resources exist on both the subject of Multics and the DPS8M simulator, this Wiki focuses specifically on how to install the simulator and Multics on your machine, how to configure it and administer it, and then how to use it. It differs from the DPS8M-related sites whose focus of attention is on the simulator itself, and from the Multics-related sites, which provide historical, informational, nostalgic, etc. background on Multics. Where appropriate, this site links to those other sites rather than duplicate information. Installing Multics To get started and install Multics on your host system, follow the Getting Started link.

New features in this release can be found in the Software Release Bulletin (SRB): * MR12.7 Software Release Bulletin You can find the tapes, SRB, the Software Installation Bulletin SIB), and other release artifacts here: Release Artifacts. You can find a QuickStart for MR12.7 here: MR12.7 QuickStart, but only use it if you don't already have a Multics system. If you do, then ignore the QuickStart and upgrade your system as described below. * Upgrading Your Multics System New Features in MR12.7 Volume Pool Support for Hierarchy Backup The Volume Backup support has long allowed tapes to be allocated from a volume pool, however up until this release, this support was not extended to the Hierarchy Backup daemons. If a volume pool is setup and configured for the incremental, catchup, or complete backup daemons, tapes will be allocated from the configured pool. A single pool can be used, or separate pools per backup type can be employed. See the info segments for the backup_dump, start_dump, catchup_dump, and complete_dump commands for more info on using volume pools with the hierarchy backup commands. See also the updated documentation on these commands in the Multics Administration, Maintenance, and Operations Commands (GB64) manual errata -- gb64.errata.info. History Comments Now Allowed in Info Segments Prior to this release, it wasn't possible to include history comments to track changes in info segments. Now with an updated version of the history_comment (hcom) command, you can. See the instructions for adding history comments in info segment by issuing the command "help info_seg.hcom". mbuild A new subsystem, mbuild, has been introduced that helps developers prepare additions to the software libraries, or changes to software in those libraries. This system helps with compilation, source/object archive updating, binding, checking history comments, performing source comparisons, and installing changes to the system libraries. The mbuild subsystem also helps system and library administrators manage installations into the system libraries. verify_info, info_seg_, and help_ The validate_info_seg command has been replaced with the verify_info command. The help_ subroutine now uses a new info_seg_ subroutine to parse info segments, and provides a more powerful user interface for displaying that information. Features that were new in MR12.6f Following is a list of new features since MR12.6e. The full list of new features since MR12.5 can be found in the SRB. input_history A new input_history_ I/O module was added to bound_video_ that allows recall and execution of previous input lines, as well as searching for prior input lines. The Multics video system provides functions for editing input lines as they are typed. It uses Emacs-like key bindings to edit input lines. However, it provides no mechanism for saving previous input lines, recalling those lines, and reexecuting them. The new input history functionality does just that. See input_history.info and input_history_.info for details. call A new call command invokes a subroutine with arguments given in a command line. It uses the declared entrypoint calling sequence to convert each command argument to a corresponding subroutine parameter's data type; invokes the subroutine; then displays any output values. library_pathname The library_pathname (lpn) command/active function was updated to return all matching pathnames when invoked as an active function. This command/AF was also updated to accept the -container control argument. cv_ptr_ The cv_ptr_ subroutine was updated to handle pointers to hardcore segments. pointer_info The pointer_info (pin) command was added to provide a command-line interface to the interpret_ptr_ subroutine. New Terminal Types Added the VT102_132C_50L and VT102_132C_78L terminal types.
