How to install ! ADSS-15 on SIMH?

We can run ! ADSS-15 on the SIMH PDP-15 emulator. First, we need to download the ! ADSS-15 kit.

Downloads

You can download the kit needed to run ! ADSS-15 on the SIMH PDP-15 emulator from the "SIMH Legacy" website:

• ! ADSS-15 kit

Using ! ADSS-15

:::tip

If you have not already installed SIMH PDP-15 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 those two files named adss15_32k.dtp and dec-15u.rim into it.

Now we will create a config file for our VM. Create a text file called pdp15.ini with the following content in the VM folder:

load dec-15u.rim 77637
ex pc
attach dt adss15_32k.dtp
set lpt disa
set lp9 ena
run

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

pdp15

After the emulator starts, you can enter D to see the list of files:

That's it! We used ! ADSS-15. We can create a shell script to make it easy to launch the VM. Create a file called adss-15.sh with the following content:

#!/bin/bash
pdp15

Now make the file executable:

chmod +x adss-15.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 ! ADSS-15 page to learn how to use it.

Windows

:::tip

You should use Linux. If you don’t 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 PDP15.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 adss-15.bat. Then you can double-click the file to launch the VM, no need to make it executable.
