(Old) Milestones:

• November 8, 2014: Multics reborn! The simulator booted Multics MR 12.5, came to operator command level, entered admin mode, created a small PL/I program, compiled and executed it, and shut down.

• May 8, 2015: The Ritter Park RCC Multics installation crashed. BCE was used to generate a dump, and when the system was rebooted, the >dumps directory was written to a tape [image]. The tape was shipped (emailed) to the SVE Multics system, where the >dumps directory was restored and analyzed.

• November 5, 2015: The Ritter Park RCC Multics installation was "[T]aken down after a month of uptime."

• December 15, 2015: Creation of Multics ALPHA release MR12.6. The first new Multics release in 15+ years. Contains Y2K fixes, etc.
