-We can run [! XVM/DOS and ! XVM/RSX](/1970s/1976/xvm-dos-rsx) on the SIMH PDP-15 emulator. First, we need to download the ! XVM/RSX and ! XVM/DOS kit.
-
-## Downloads
-
-You can download the kit needed from the ["SIMH Legacy"](http://simh.trailing-edge.com/) website:
-
-- [! XVM/RSX and ! XVM/DOS kit](http://simh.trailing-edge.com/kits/xvmrsx_simh_kit.zip)
-
-## Using ! XVM/DOS & ! XVM/RSX
-
-:::tip
-
-If you have not already installed SIMH PDP-15 emulator, see [the VirtualHub Setup tutorial on how to do so](https://setup.virtualhub.eu.org/simh-pdp15/) 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 `xvmrsx_rp02.dsk` and `rpboot.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:
-
-```ini
-set cpu api
-set cpu xvm
-set ttix lines=5
-a ttix 2311
-a rp0 xvmrsx_rp02.dsk
-l rpboot.rim 77637
-run
-```
-
-![pdp15.ini](./xvm-dos-rsx-SIMH-1.webp)
-
-Now open a terminal and move to the VM folder. Run the following command to start the emulator:
-
-```bash
-pdp15
-```
-
-If you get a prompt asking if you want to allow network access, click on yes. On Linux, you may want to run the above command with `sudo` or as `root`, for it to work properlly.
-
-![pdp15](./xvm-dos-rsx-SIMH-2.webp)
-
-When asked for a date, enter it in `MM/DD/YY` format. You _cannot_ use backspace to erase characters, even if it looks like you can. Try entering a date from 1980s or 90s, to avoid any problems.
-
-Now that ! XVM/DOS is ready, let's run some commands on it. Type `PIP` and press enter to start PIP. Then run `L TT_SY` to see the list of files.
-
-![List of files in ! XVM/DOS](./xvm-dos-rsx-SIMH-3.webp)
-
-That's it! We used ! XVM/DOS. Now, to run ! XVM/RSX, we first need to close PIP. Do so by pressing `Ctrl` + `C`. Then run `RSX` to start ! XVM/RSX.
-
-:::tip
-
-Telnet client may not be installed by default depending on your host operating system. You can install it by following [this VirtualHub Setup tutorial](https://setup.virtualhub.eu.org/telnet/).
-
-:::
-
-To connect to ! XVM/RSX, we need to use telnet. Run `telnet 127.0.0.1 2311` in a new terminal window, and then press `Ctrl` + `T`. When asked for disk type, enter `RP` and press enter. You will be connected to ! XVM/RSX.
-
-![! XVM/RSX](./xvm-dos-rsx-SIMH-4.webp)
-
-That's it, we used ! XVM/RSX. To stop the VM, go back to the main terminal window, and press `Ctrl` + `E`. Then type `exit` and press enter. We can create a shell script to make it easy to launch the VM.
-
-### Linux
-
-Create a file called `xvm-dos-rsx.sh` with the following content:
-
-```bash
-#!/bin/bash
-pdp15
-```
-
-Now make the file executable:
-
-```bash
-chmod +x xvm-dos-rsx.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/1976/xvm-dos-rsx/#manuals) on the [main ! ! XVM/DOS and ! XVM/RSX page](/1970s/1976/xvm-dos-rsx/) to learn how to use them.
-
-### Windows
-
-Create a file called `xvm-dos-rsx.bat` with the following content:
-
-```bash
-pdp15
-```
-
-Now you can start the VM by double-clicking the shell script. See the [manuals section](/1970s/1976/xvm-dos-rsx/#manuals) on the [main ! XVM/DOS and ! XVM/RSX page](/1970s/1976/xvm-dos-rsx/) to learn how to use it.
