+
+We can run [! RT-11 v2](/1970s/1975/rt-11-v2) on the SIMH PDP-11 emulator. First, we need to download the ! RT-11 v2 image.
+
+## Downloads
+
+There are two different versions of RT-11 v2, whose image is available for us to use/ They are RT-11 v2B and v2C. Both of them are mostly same, and you can use either. You can download the image needed to run ! RT-11 v2 on the SIMH PDP-11 emulator from here:
+
+- [! RT-11 v2B image](https://github.com/InstallerLegacy/RT11DV50/raw/main/RTV2RK.B)
+- [! RT-11 v2C image](https://github.com/InstallerLegacy/RT11DV50/raw/main/RTV2RK.C)
+
+## Using ! RT-11 v2
+
+:::tip
+
+If you have not already installed SIMH PDP-11 emulator, see [the VirtualHub Setup tutorial on how to do so](https://setup.virtualhub.eu.org/simh-pdp11/) on Linux and Windows.
+
+:::
+
+Create a folder somewhere to store the files for this VM, and move the disk image file into it.
+
+Now we will create a config file for our VM. Create a text file called `pdp11.ini` with the following content in the VM folder, if you chose the v2B image:
+
+```ini
+att rk0 RTV2RK.B
+boot rk0
+```
+
+If you chose v2C instead, make your `pdp11.ini` file like this:
+
+```ini
+att rk0 RTV2RK.C
+boot rk0
+```
+
+![pdp11.ini](./rt-11-v2-SIMH-1.webp)
+
+Now open a terminal and move to the VM folder. Run the following command to start the emulator:
+
+```bash
+pdp11
+```
+
+![pdp11](./rt-11-v2-SIMH-2.webp)
+
+After the emulator starts, you will get a `.` prompt. Type `R PIP` and press enter to start PIP. Now run `/L` to get a list of files.
+
+![List of files in ! RT-11 v2](./rt-11-v2-SIMH-3.webp)
+
+To exit PIP, press `Ctrl` + `C`. To exit the emulator, type `Ctrl` + `E`, and then run `exit`.
+
+That's it! We used ! RT-11 v2. We can create a shell script to make it easy to launch the VM.
+
+### Linux
+
+Create a file called `rt-11-v2.sh` with the following content:
+
+```bash
+#!/bin/bash
+pdp11
+```
+
+Now make the file executable:
+
+```bash
+chmod +x rt-11-v2.sh
+```
+
+Now you can start the VM using the shell script. For example, on KDE you can right-click the file and choose `Run in Konsole` or on GNOME, where you can right-click the file and choose `Run as executable`. The VM will start.
+
+See the [manuals section](/1970s/1975/rt-11-v2/#manuals) on the [main ! RT-11 v2 page](/1970s/1975/rt-11-v2) to learn how to use it.
+
+### Windows
+
+Create a file called `rt-11-v2.bat` with the following content:
+
+```bash
+pdp11
+```
+
+Now you can start the VM by double-clicking the shell script. See the [manuals section](/1970s/1975/rt-11-v2/#manuals) on the [main ! RT-11 v2 page](/1970s/1975/rt-11-v2) to learn how to use it.
