What Upgrade was created by Routerworks
Here is what I have that works well with a parallel port. I don't want to change that. I sometimes have to reboot once or twice to have it load. Not a big problem. Overall I am very happy with it performance. Just thought I might consider upgrading as most (not all) things improve ovver time.
Here is what I have:Linux Debian 4.19.0-21-rt-amd64 #1 SMP PREEMPT RT Debian 4.19.249-2 (2022-06-30)
It's an older Dell e521 computer. Might have to upgrade the computer. Again, I'm fine with the "No IRQ handler" at start up, then it boots ok. Just wondering if someone who knows more than me would make a suggestion as I don't want to loose what I have.
It's a great cnc operating system.
Thanks in advance for any suggestions.

Keep a backup of the config folder, on at least two USB's or hard drives, do not worry much about other stuff and updates.
If the machine is working properly, leave it as is.
And you can always find even older ISO images to download on the downloads page.
If you do have a spare PC, then install whatever you want top test, copy the config file and check if everything works properly.
For parallel port systems, some older Dell Optiplex, some HP Z200/220 and Z400, and some Lenovo, come with parallel port or header for it on the board, just be aware that forum member "Unknown" had issues with some Lenono not working with general purpose adapters.

Thanks a lot for your advice. It seems Dell Optiplex and HP Z series are well regarded. I'll follow your guidelines. It seems the safest way to go considering I have a working system. Not sure between version 2.9.4 or 2.9.5 considering I am using a parallel port.

Stick to 2.9.4 for the time being, some issues have arisen, no doubt they will be rectified in a timely manner.
Elaborating on the Lenovo thing, whilst a parallel port in provided, it requires a Lenovo header cable. From what I can gather the cable uses some pin or pins to enable the parallel on what was onced referred to the SuperIO chip. Without this cable the parallel port is neither seem in the bios setup nor the Linux hardware probe. With the cable everything is fine.
Some basically testing on an old parallel port 3rd gen I5 proved it to be a suitable candidate.
But it all comes down to local availability, resellers or what you can find on the street.
