./DECSys-7-SIMH-3.webp We can run ! DECSys-7 on the SIMH PDP-7 emulator. First, we need to download the ! DECSys-7 kit. You can download the kit needed to run DECSys on the SIMH PDP-7 emulator from the "SIMH Legacy" website: 1 ! DECSys-7 on SIMH

How to install ! DECSys-7 on SIMH?

SIMH PDP-7 emulator with ! DECSys-7

We can run ! DECSys-7 on the SIMH PDP-7 emulator. First, we need to download the ! DECSys-7 kit.

Downloads

You can download the kit needed to run ! DECSys-7 on the SIMH PDP-7 emulator from the "SIMH Legacy" website:

Using ! DECSys-7

:::tip

If you have not already installed SIMH PDP-7 emulator, see the VirtualHub Setup tutorial on how to do so 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:

att dt2 decsys.dtp
att dt3 scratch.dtp
load decsys.rim 17640
run

pdp7.ini

Now open a terminal and move to the VM folder. Run the following command to start the emulator:

pdp7

pdp7

After the emulator starts, type CONTEN followed by !. All commands in ! DECSys-7 execute when you type !. You will see the following screen:

CONTEN!

Type S,L,W followed by !. It will list all the files available on the disk.

List of files in ! DECSys-7

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:

#!/bin/bash
pdp7

Now make the file executable:

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 on the main ! DECSys-7 page to learn how to use it.

Windows

:::tip

You should use Linux. If you dont know how to install a Linux distro, see our tutorials on how to install Kubuntu, a beginner-friendly distro.

:::

On Windows, you need to place the PDP7.exe file you downloaded in this tutorial 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.
