Getting Started

There are several ways to get Multics installed on your machine. You can download a "QuickStart" image that has Multics already installed, saving you the work of doing what is called a "cold boot" of Multics. The "cold boot" involves starting the DPS8M emulator with a non-existent "root logical volume" (RLV) and booting a Multics tape image, loading tape images, and generally following the Multics cold boot instructions as were followed by users with real Multics hardware. The QuickStart includes an RLV immediately after a cold boot. It is ready to be customized with a site name, projects, and users. I recommend you start with the QuickStart and later, if you really want to perform a cold boot (for the experience), you can.

How to Run Multics on DPS8M

The document located here: Running_Multics_on_DPS8M.pdf provides an in-depth "how-to", as well as background info, for running Multics under the DPS8M emulator.


The QuickStart does not come with an emulator. You will have to download or build an emulator appropriate for your platform. You will also need to be have a computer running one of the supported operating systems:

  • Linux (64-bit)
  • Linux (32-bit) - not available yet
  • Mac OS X
  • Windows 7, 8, or 10
  • Raspberry Pi (with a 32-bit ARMv7 processor)

Follow the instructions in the following link in order to download or build the emulator.

Installing the DPS8M emulator

Once you have a working DPS8M emulator on your machine, follow these instructions to download, unzip, and run the QuickStart.
