# How to install ! DECSys-7 on SIMH?

We can run [! DECSys-7](/1960s/1965/decsys) on the SIMH PDP-7 emulator. First, we need to download the ! DECSys-7 kit.

You can download the kit needed to run ! DECSys-7 on the SIMH PDP-7 emulator from the ["SIMH Legacy" website](http://simh.trailing-edge.com/):

## Using ! DECSys-7

If you have not already installed SIMH PDP-7 emulator, see [the VirtualHub Setup tutorial on how to do so](https://setup.virtualhub.eu.org/simh-pdp7/) 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 `decsys.dtp` and `decsys.rim` into it.
|
|||
|
|
|
|||
|
|
Now we will create a config file for our VM. Create a text file called `pdp7.ini` with the following content in the VM folder:
|
|||
|
|
|
|||
|
|
```ini
|
|||
|
|
att dt2 decsys.dtp
|
|||
|
|
att dt3 scratch.dtp
|
|||
|
|
load decsys.rim 17640
|
|||
|
|
run
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
Now open a terminal and move to the VM folder. Run the following command to start the emulator:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
pdp7
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
After the emulator starts, type `CONTEN` followed by `!`. All commands in ! DECSys-7 execute when you type `!`. You will see the following screen:
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
Type `S,L,W` followed by `!`. It will list all the files available on the disk.
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
That's it! We used ! DECSys-7. We can create a shell script to make it easy to launch the VM. Create a file called `DECSys-7.sh` with the following content:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
#!/bin/bash
|
|||
|
|
pdp7
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Now make the file executable:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
chmod +x DECSys-7.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/decsys/#manuals) on the [main ! DECSys-7 page](/1960s/1965/decsys) 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 `PDP7.exe` file you downloaded in [this tutorial](https://setup.virtualhub.eu.org/simh-pdp7#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 `DECSys-7.bat`. Then you can double-click the file to launch the VM, no need to make it executable.
