As long as those manufacturing systems were air-gapped and working, I can understand being conservative with changes. Of course at some point you're at risk of hardware failures too, for things that are likely NLA.

Yeah, that's really the biggest issue with these systems. Were I one of these manufacturers I'd invest in getting the current software running in a VM specifically to make it easier to transition to new hardware. The last thing they'll want to deal with is that their software was written for Sun Spark and that no longer exists.
That said, hard to go wrong porting over the x86 at this point.
