This is most useful for retrocomputing, and that’s gonna be the target demographic.

While it’s true that industrial and manufacturing sometimes have really old hardware, that’s usually less due to them not having newer options and more due to preferring something tried and true (it “just works” for their workflow) or the sheer economics of upgrading; in most of those cases, there’s already a flow for interfacing with newer technology (FTP or USB 1.0/2.0 commonly). So this device wouldn’t offer much benefit, if any.

I have seen EDM machines with floppy interfaces. A great upgrade for those is a floppy emulator.
