How to install ! DECSys-7 on SIMH?
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
Now open a terminal and move to the VM folder. Run the following command to start the emulator:
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.
Linux
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
Create a file called DECSys-7.bat with the following content:
pdp7
Now you can start the VM by double-clicking the shell script. See the manuals section on the main ! DECSys-7 page to learn how to use it.
