TUTORIAL Last 32 bit version of IncrediblePBX for Intel x86 CPU?

[Halea]

What would be the most recent 32 bit version of IncrediblePBX that would work on an Intel x86 CPU? More precisely we're trying to run IncrediblePBX for fun on an old relic with Intel Atom 270 + 1GB of RAM and 32GB of flash memory storage. The hardware is of our own design from some years ago that we have found in our junk pile as we were cleaning our lab. I've just installed Ubuntu 18.04 on it and it worked flawlessly.
On sourceforge I saw that IncrediblePBX 13-13 has specific release for Ubuntu 18 32 bit version. But I wonder if a more recent version would install.

13-13 is probably the last 32-bit code, and there may be issues with the install scripts. I tested a VirtualBox edition several weeks ago and it still worked fine: https://www.voip-info.org/forum/threads/stability-matters.26742/

Thank you Ward. I noticed that there are 2 packages; 13-13 and 13-13.10. Should I try 13-13.10 or stick to the lower version?

Why try either of these? What is the benefit of running an out of date/unsupported system with out of date/unsupported software?

It was painfully slow to install, but here it is!
The only obvious issue that I ran into was that nowadays ifconfig is not installed by default. I had to install it manually. There may be other issues that I haven't seen yet as I didn't configure trunks or extensions to actually use it. But the web servers are up, both webmin and the IncrediblePBX GUI show up and seem to work correctly.

@Samot : As I mentioned in my OP this is just for fun on a piece of hardware that I designed and produced for my business many moons ago. It only has "yes we can" benefit

If anyone is interested in knowing how I installed my 32 bit legacy machine here comes the full recipe.

Some additional installs turned out to be necessary as the 32 bit Ubuntu distro has changed quite a bit between its first iteration and the 6th over the years. (and most importantly the repositories now hold different versions of php)
I initially used an older version from my junk box which allowed me to install with fewer headaches. But when I tried to use the latest mini ISO (because I messed up my install doing foolish things) all the php issues showed up.
The following steps allow for a clean install without requiring any modifications to Ward's original scripts.
(There are many places to get php 5.6 but I prefered taking it from an Ubuntu PPA to ensure that all dependency issues were addressed automatically)

So without further ado:

How to install IncrediblePBX13-13.10 on Ubuntu 18.04 32 bit ?

1) Make sure that the network connection works on the target machine (PBX host).
2) Install Ubuntu 18.04 32bit from the latest mini ISO cd, which installs version 18.04.6.
3) Reboot. Create root user. Login as root.
4) ifconfig will be missing. To install it:
sudo apt install net-tools
5) php5 will be missing. To install it:
sudo apt install software-properties-common
then
sudo add-apt-repository -y ppa:ondrej/php
sudo apt update
sudo apt install php5.6
reboot
6) Install IncrediblePBX per Ward's instructions:
cd /root
wget http://incrediblepbx.com/incrediblepbx-13-13.10U-LEAN.tar.gz
tar zxvf incrediblepbx-13-13.10U-LEAN.tar.gz
# No need to create swap as Ubuntu installation took care of it.
./Incredible*
Reboot (happens automatically)
cd /root
./Incredible*
7) Finally do the following (always per Ward's instructions):
-Create an admin password for GUI access: /root/admin-pw-change
-Create an admin password for Apache web access: htpasswd /etc/pbx/wwwpasswd admin
-Configure the correct timezone for your server: /root/timezone-setup
-Retrieve your PortKnocker setup like this: cat /root/knock.FAQ
-Add IPtables WhiteList entries for remote access: /root/add-ip or /root/add-fqdn
8) Reboot
9) Check out the PBX GUI webpage as well as Webmin page. They should both be working.
10) Add a couple of extensions and a trunk (+ routes). Incoming, outgoing, extension to extension - should all work.
