Failed Parallel Port on system, Recommended Easiest Upgrade Solution ?

Parrallel port has failed on my old computer , running Ubuntu 10.4 and EMC2 2.4.6 . Milling machine has Pico USC , Microkinetics Steppers , Linear Scales for Position feedback.  Old computer is a mishmash of crap that has no network capabilities.
I need the easiest upgrade path , for a computer and Software . Im old and not very tech savy!  I may go to a Mesa board if it would make things easier. Any and all recommendations!

No eBay APP ID and/or Cert ID defined in Kunena configurationThe below is what I use for testing and messing around with Linuxcnc. I'm a little biased towards Lenvo, I have a couple of ThinkPads, 2 ThinkCentres and a ThinkStation. Never had an issue, my T530 ThinkPad is my daily driver.

You'll need a parallel motherboard port cable (otherwise you can't enable the PP in the BIOS)

A small SSD is not a bad idea as well 128GB is enough.

You wont need to do much to your configs, except the small diffs from 2.7 to 2.9.

Used old Dell Optiplex 980 in Tower version has a built in parallel port, plenty can be found for very cheap, you can probaly just yank the old hard drive and put it in the new PC and everything should work. Granted the hard drive works.

I did find a USB Stick with a full back up set of files. I know the hardware must be fine , I transplanted the computer from the other mill. It would make the steppers at least jump. The computer would not even boot from the ISO so I could reload the OS.

Use Rufus to write the ISO to USB, or Balena Etcher should also work.
Also make sure the BIOS is set to boot from USB first, or, press repeatedly the F12 button at power on till you see the bootable device list. F11 on some PC's, F8 on Asus, etc.

Ive done exactly that , Bios was set accurately , but it still would not boot from the USB Stick. I also must not have root access. The Bios doesnt show a password installed ., but if i use SUDO in the terminal , it asks for my password ?
