It is not that simple.
For hardware attacks, older hardware are probably safe since the attacks are specifics to some newer features. I really doubt you can deliver a Spectre attack on anything up until the Pentium or even later.
On the software side, there could be some security bugs to which some older version could be vulnerable since there were not the vulnerable code at the time. Granted, there could be some security bugs that were not yet discovered in older codebase.

I had a Samsung SL-C430W (a laser color printer) and it still work really well after 7 years, but admitedly I don’t print that much and only a really few time a photos. On the other hand I printed on a variety of types of paper, from the standard one to the decals paper to paper to print shirts and lastly to paper to print on wood and it never disappointed.

Cheap toners (from Amazon) and really robust. But I think it is no sold.

Yep, that one. Not checked the name 😬

If you are willing to pay the price, you can try Moment Of Invention. It has also a fully functional time limited demo. I worked with the demo and, while for now I use Freecad, I must admit that it is pretty good
