+You can download the kit needed to run ! HP 2100 DOS-III on the SIMH HP 2100 emulator from the GitHub user [rsanchovilla's](https://github.com/rsanchovilla/) [software kits repository](https://github.com/rsanchovilla/Software_Kits):

+
+## Using ! HP 2100 DOS-III
+
+:::tip
+
+If you have not already installed SIMH HP 2100 emulator, see [the VirtualHub Setup tutorial on how to do so](https://setup.virtualhub.eu.org/simh-hp2100/) 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 files named `DOS-III_0.disc` and `DOS-III_1.disc` into it.
+
+Now we will create a config file for our VM. Create a text file called `hp2100.ini` with the following content in the VM folder:
+
+```ini
+set cpu 2116
+set cpu 32k
+SET CPU EAU
+set tty sc=11
+set clk sc=12
+set ptr sc=13
+set tbg sc=17
+set ptp sc=20
+set tty autolf
+set console del=177
+set dpc 13210A
+set dpc sc=22
+set dpc ena
+att dpc0 DOS-III_0.disc
+att dpc1 DOS-III_1.disc
+set msd sc=30
+set msd ena
+boot dpc0
+echo
+go
+```
+
+![hp2100.ini](./HP-2100-DOS-III-1.webp)
+
+Now open a terminal and move to the VM folder. Run the following command to start the emulator:
+
+```bash
+hp2100
+```
+
+![hp2100](./HP-2100-DOS-III-2.webp)
+
+Type `:DATE,10JULY1975` when you encounter the `@` prompt, and press enter. You can change the date as you wish. After you see some lines, and then another `@` prompt, type `:JOB` and press enter.
+
+To see list of user files, run `:LIST,U,1`.
+
+![List of User FIles in ! HP 2100 DOS-III](./HP-2100-DOS-III-3.webp)
+
+That's it! We used ! HP 2100 DOS-III. We can create a shell script to make it easy to launch the VM.
+
+### Linux
+
+Create a file called `HP-2100-DOS-III.sh` with the following content:
+
+```bash
+#!/bin/bash
+hp2100
+```
+
+Now make the file executable:
+
+```bash
+chmod +x HP-2100-DOS-III.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](/1970s/1973/hp2100dos-iii/#manuals) on the [main ! HP 2100 DOS-III page](/1970s/1973/hp2100dos-iii/) to learn how to use it.
+
+### Windows
+
+Create a file called `HP-2100-DOS-III.bat` with the following content:
+
+```bash
+hp2100
+```
+
+Now you can start the VM by double-clicking the shell script. See the [manuals section](/1970s/1973/hp2100dos-iii/#manuals) on the [main ! HP 2100 DOS-III page](/1970s/1973/hp2100dos-iii/) to learn how to use it.
