I am certainly not an export but... Essentially PP tells the Mesa card the desired step rate and the number of steps and it outputs the steps independently of the computer. This means that interruptions to service the UI, display a web page or whatever doesn't affect the stepping. With Mach3 and a parallel port the computer must do everything.
Right.
Why do people get so het up on 'it's old technology' with parallel?. It works.
It's basically a 3 axis mill. All it needs is the amount of I/O that a standard lpt port gives you.
So. You're sticking with Mach3?.
You're worried about the onboard port failing?.
Just get a pci parallel port card and shove it into a micro atx pc motherboard and connect lpt cable to the Mill.
Install Windows XP / 7, 32bit os, Mach3, check port/pin no's, done!.
When/if that card fails, shove another one in.
Don't know about reliability but if they weren't reliable, they wouldn't exist, right?.
Between £20 - £50.
Basically a parallel breakout so pc & mach still does the work (pci express). (U.K.)

Because it breaks, I have just had two hard drives fail. One of which held my copy of solidworks .Have you seen the price they now want for solidworks. Old computers only excess because newer ones here in the uk are more cloud based systems. But it’s getting harder to trust old technology. I would like to use a more upto date pc too run my software. That’s me, it’s a bit like owning a car, there comes a time it is just not going to make that long trip know matter what money you have put into it.
That's bad fortune that is. Did you not make an iso image of the drive after everything was installed?.
All my pc's are built and not 'off the shelf' and I tend to make a habit of changing drives every 5 years or so. Plus the odd upgrade here and there.
Just had to change a perfect motherboard (age 2008) all because it wouldn't read a new drive
(At least I can read 3tb+ now I suppose).
You have to watch these new ones, Advert is all singing / dancing, get it home, realise it can't store bugger all!.
'Cloud based' is all about forcing you into subscriptions. All a con tbf. Plus the u.k. infrastructure sucks.
I'm not totally 'old skool'. I have bought a new i7 w10 laptop for when I get uccnc + uc300 wired in and set up.
Also I use handbrake a lot and my most reliable codecs will only work under win7, perfect every time. Under win10 it was seriously hit and miss.
Anywhoo. A simple parallel pci card is the simple cheap route for the op's worry afaic.
If you don't trust cloud backups, there's always big local drives.
While spinning disks used to be cheaper, SSDs have come down so much in price, and don't wear out by spinning, I've moved all my storage over.
$360 for 4 TB of quality SSD storage? Don't mind if I do :-) https://amzn.to/3BXMqED
(Yes, if bulk storage is the ONLY thing you're doing, and you're not worried about earthquakes while the spindle is running, you can save another hundred or two by sticking with the spinny rust, but ... waiting for backups/storage has a cost too!)
the problem with hard drives is knowing when to clone them before they are cooked
In regards to old technology , your wanting to run mach 3 on new tech , except as much as I like mach I have to admit that it is an old tech software . You can add plugins to replace the pp but thats a bandage to an old unsupported software . You can try the uc100 but don't be surprised if your machine stops in the middle of a run and shows an error message , which will force you to completely restart mach and start all over . Like I said previously I have 4 sitting in a drawer and I've had to deal with their quirks until I got fed up and pulled them
I live in Canada and I can completely empathize with the taxes because most of my money goes to one tax or another other , but a guys got to do what he's got to do . If you want the most up to date control for your tormach then pathpilot and a mesa card is your best choice , and whatever pc , hard drive , etc can be your choice , but keep in mind that pathpilot/linuxcnc plays better on some pc's than others
If you run a NAS with a redundant array, you should never get bit with failed HDD. Took 10 years for a drive in my Synology to fail and it was hot swappable.
But back on topic. As said there was a reason why Tormach went to Linuxcnc. Don't fight it. Just pay the money and upgrade your machine with PathPilot. Anything else will be a compromise and devalue your asset. Unlike Mach, Linuxcnc is still actively developed. So is PathPilot.
AS far as PC's playing, that is not that much of an issue. Some hardware may not have driver support in Linux but the real thing is to make sure that the PC you choose does not have excessive latency. There are tests provided you can do to check that.
BTW, I know another UC100 that went in a drawer today as a newcomer migrates his Novakon to Linuxcnc... because of unreliability with mach

You have not lost the software just the operating system most likely failed to connect with the drive
If you have another computer, that can use another drive in it, you can connect the drive as a slave and you will be able to get to your software or anything on the drive that you need or want
This is money to the computer Tec's, that most don't know, they do it the hard way with software which also fails a lot, but it is as simple as going in the back door, it will just show up as a drive and you can open anything on it you want

Yes a SSD does not wear out because of spinning but it has a short life in comparison it only has write / rewrite a few times and then it is done, there average life is between 2 years to 5years depending on the use some are said to be able to last up to 10 years that has not happened yet so I would not count on it

Or perhaps $185 depending on the appropriate Mesa card.
With all the prices being thrown out there I think I would just buy a uc400eth.
Get an IDC26 to DB25 cable for it to go into the pp of machine from port #1. Done!.
Then get another cable and a cheap £5 bob for port #2 and play around with a 4th axis and building a tool changer.
Should be way less than $200 for a uc400+ cables.
(Or you could play hit or miss with uc100).
Or fork for pathpilot, mesa, and linux.
