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.

Linux

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

Create a file called adss-15.bat with the following content:

pdp15

Now you can start the VM by double-clicking the shell script. See the manuals section on the main ! ADSS-15 page to learn how to use it.
