+
+We can run ! Unix v5 on the Ersatz-11 emulator. First, we need to download the ! Unix v5 kit.
+
+## Downloads
+
+You can download the kit needed to run ! Unix v5 from the [“SIMH Legacy” website](http://simh.trailing-edge.com/):

+
+## Using ! Unix-v5
+
+:::tip
+
+If you have not already installed Ersatz-11 emulator, see [the VirtualHub Setup tutorial on how to do so](https://setup.virtualhub.eu.org/ersatz-11/) on Linux and Windows.
+
+:::
+
+Extract the archive you downloaded. Inside you will find a file called several files. Create a folder somewhere to store the files for this VM and move the `unix_v5_rk.dsk` file into it.
+
+Now we will create a config file for our VM. Create a text file called `e11.ini` with the following content in the VM folder:
+
+```ini
+set cpu 45
+mount dk0: unix_v5_rk.dsk /rk05
+boot dk0:
+```
+
+![e11.ini](./unix-v5-Ersatz-11-1.webp)
+
+Now open a terminal and move to the VM folder. Run the following command to start the emulator:
+
+```bash
+e11
+```
+
+![e11](unix-v5-Ersatz-11-2.webp)
+
+After the emulator starts, you will get a `@` prompt. Type `unix` and press enter to run the `unix` kernel. You will be asked to log in. Type `root` and press enter to log in. There is no password.
+
+You can now run `ls` to see the list of files. To change directory, you need to use the `chdir` command, `cd` is not available.
+

+
+That's it! We used ! Unix-v5. To exit the emulator, press `Shift` + `Enter` and then type `exit` and press enter. We can create a shell script to make it easy to launch the VM.
+
+### Linux
+
+Create a file called `unix-v5.sh` with the following content:
+
+```bash
+#!/bin/bash
+e11
+```
+
+Now make the file executable:
+
+```bash
+chmod +x unix-v5.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/1974/unix-v5/#manuals) on the [main ! Unix-v5 page](/1970s/1974/unix-v5) to learn how to use it.
+
+### Windows
+
+Create a file called `unix-v5.bat` with the following content:
+
+```bash
+e11
+```
+
+Now you can start the VM by double-clicking the shell script. See the [manuals section](/1970s/1974/unix-v5/#manuals) on the [main ! Unix-v5 page](/1970s/1974/unix-v5) to learn how to use it.
