What are the use cases for this? I'm guessing retro computing and possibly very old machines tied to very obsolete hardware that can't be virtualized (e.g. manufacturing controls).
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.

Which kind of makes sense.
