# How to install ! 4K DMS on SIMH?

We can run [! 4K DMS](/1960s/1965/4kdms) on the SIMH PDP-8 emulator. First, we need to download the ! 4K DMS kit.

## Using ! 4K DMS

If you have not already installed SIMH PDP-8 emulator, see [the VirtualHub Setup tutorial on how to do so](https://setup.virtualhub.eu.org/simh-pdp8/) on Linux and Windows.
|
|||
|
|
|
|||
|
|
:::
|
|||
|
|
|
|||
|
|
Extract the kit you downloaded. Inside you will find several files. Create a folder somewhere to store the files for this VM, and move the file named `dms.df32` into it.
|
|||
|
|
|
|||
|
|
Now we will create a config file for our VM. Create a text file called `pdp8.ini` with the following content in the VM folder:
|
|||
|
|
|
|||
|
|
```ini
|
|||
|
|
set df enabled
|
|||
|
|
att df dms.df32
|
|||
|
|
boot -d df
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
Now open a terminal and move to the VM folder. Run the following command to start the emulator:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
pdp8
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
After the emulator starts, type `PIP` and press enter. Then press `L`. You will see the following screen:
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
Type `S:` and press enter. It will list all the files available on the disk.
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
That's it! We used ! 4K DMS. We can create a shell script to make it easy to launch the VM. Create a file called `4K-DMS.sh` with the following content:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
#!/bin/bash
|
|||
|
|
pdp8
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Now make the file executable:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
chmod +x 4K-DMS.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](/1960s/1965/4kdms/#manuals) on the [main ! 4K DMS page](/1960s/1965/4kdms/) to learn how to use it.

### Windows

You should use Linux. If you don’t know how to install a Linux distro, see [our tutorials on how to install Kubuntu](https://setup.virtualhub.eu.org/tag/os/), a beginner-friendly distro.
|

|
On Windows, you need to place the `PDP8.exe` file you downloaded in [this tutorial](https://setup.virtualhub.eu.org/simh-pdp8#windows) in the VM folder. Then you can follow the above tutorial as usual. The shell script will not work on Windows. You need to rename it to `4K-DMS.bat`. Then you can double-click the file to launch the VM, no need to make it executable.
