If the computer is air-gapped, that is one thing. If the computer is on a network and that network is air gapped, that is something else. Oof that computer is on a network and any machines on that network have access to the Internet, then that old insecure machine should be assumed to be on the Internet.
Just look at the many exploits for non-Internet connected LAN printers.

And when you have old tools that allow you to, for example, load information off a tape, you have an attack vector that probably hasn’t been secure because it was written before we figured out that security was important (because people suck) and no one has gone back to look at how exploitable that code is on a modern system.
What we have here is a failure to communicate.
