## My Turnkey-5 Implementation
Several people have asked me how I managed to get a mainframe running on my laptop. This post explains how I did that. Enjoy!
### Setting Up The Host Machine
You can run the entire setup from your native workstation, if you want. But that's not what I did. for the sake of portability, compatibility, and stability, I constructed a virtualbox using Debian 12, on which to host the Turnkey package:
* ISO: Debian 12 (64bit)
* CPU(s): 2 (explained in a moment)
* Acceleration: Paging, VT-x/AMD-V, PAE/NX, KVM
* RAM: 1024MB
* Display: Default
* Storage: VDI 60GB
* Network: **Bridged**
The reason for 2 CPUs is because when we set up the TK5 system, it will include two of its own mainframe cpus, and we want to be able to take advantage of that on the host.
The reason for the BRIDGED adapter, is because we want to make the mainframe accessible from other devices on the local subnet. If everything you do is local to the host machine, then a normal NAT connection will also work.
Go through the normal debian installation process. Don't include a desktop environment, because it won't be needed. Make sure to include the ssh server as part of the installation, and make sure you're able to ssh into the the VM from your host:
<pre class="decterm">
gmgauthier@boethius $ ssh sysa
Linux tk5-sysa 6.1.0-23-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.99-1 (2024-07-15) x86_64

### Installing Turnkey
Next, you'll want to install the base turnkey package to the root account. You'll be working entirely from root now. Use wget to download the zip file from [Eric Prince's Turnkey Page](https://www.prince-webdesign.nl/images/downloads/mvs-tk5.zip), to the root account. Once there, unzip it in place. your director should now have an `mvs-tk5.zip` file, and an `mvs-tk5` directory:
<pre class="decterm">
gmgauthier@tk5-sysa:~$ su root
Password:
root@tk5-sysa:/# cd /root
root@tk5-sysa:~# ls -l
total 432068
-rw-r--r-- 1 root root 34 Aug 3 16:35 blkid.txt
drwxr-xr-x 3 root root 4096 Aug 3 17:05 go
drwxr-xr-x 20 root root 4096 Aug 4 03:19 mvs-tk5
-rw-r--r-- 1 root root 442420923 Jul 29 22:25 mvs-tk5.zip
drwxr-xr-x 10 root root 4096 Aug 3 17:05 virtual1403
root@tk5-sysa:~#
</pre>
cd into the `mvs-tk5` directory. This is roughly what you should see:
<pre class="decterm">

### Configuring Turnkey
### Running The Turnkey MVS Instance
At this point, there is technically only one other thing that is necessary to get the system going. You will want to do this so that you can interact with the machine directly from the console. `cd` into the "unattended" directory:
<pre class="decterm">
root@tk5-sysa:~/mvs-tk5# cd unattended
root@tk5-sysa:~/mvs-tk5/unattended# ls -l
total 20
-rw-r--r-- 1 root root 8 Dec 2 09:52 mode
-rwxr-xr-x 1 root root 788 Jul 23 2023 set_console_mode
-rwxr-xr-x 1 root root 830 Nov 28 2013 set_console_mode.bat
-rwxr-xr-x 1 root root 792 May 30 2023 set_daemon_mode
-rwxr-xr-x 1 root root 828 May 30 2023 set_daemon_mode.bat
</pre>
Run the `set_console_mode` script:
<pre class="decterm">
root@tk5-sysa:~/mvs-tk5/unattended# ./set_console_mode
Hercules console mode activated for unattended operations mvs
Press any key to continue...
</pre>
Once that's done, return to the base directory. From there, we can launch the system with the `mvs` command, which will load the master console directly:
<pre class="decterm">
root@tk5-sysa:~/mvs-tk5/unattended# cd ..
root@tk5-sysa:~/mvs-tk5# ./mvs
