2014-11-08: The SIMH-based simulator booted Multics MR12.5, came to operator command level, entered admin mode, created a small PL/I program, compiled and executed it, and shut down.

2015-11-05: The Ritter Park RCC Multics installation was "[T]aken down after a month of uptime."

2016-01-20: The DPS8M Development Team released Multics Release MR12.6d.

The purpose of this project is to create a simulator reproducing in sufficient detail the function and capabilities of the Honeywell/Bull dps-8/m processor with the ultimate goal of resurrecting Multics.

    What a nostalgic pleasure to boot MULTICS again, thanks for doing this.

    Astonishing to be able to run the first ever mainframe I used (Cardiff - 1983) on my PC. A brilliant effort guys.

    The dps8m simulation team has worked incredibly hard to get Multics available again. A QuickStart installation is also now available but it is also possible to bring up a simulated Multics "the hard way" if desired. This project will be valuable to operating system researchers, enthusiasts, and of course, former Multics users, administrators, and developers. Thank you for the huge effort!

    At last, someone made the giant leap. Multics reborn. A very good and promising start. A terminal accepting commands seems close (and it'll be faster than the 1200 bd at the time). Please keep up the good work!
