At the very least, being able to read the source code gives you a Hell of a head start on writing a new driver for an appropriate OS (and by that I mean Linux, obviously). Saves a whole reverse-engineering step.
I’m not saying creating an entire project to adapt the controller and software stack to modern systems would be cheap or easy, but it’s possible – and more to the point, seemingly less expensive than buying the new microscope for “hundreds of thousands of €” (especially in the long run, since the company is likely to pull the same shit over and over again), even if you’ve got to pay a gaggle of comp-e grad students to put it together for you.

Also, the “a card that only plugs into 30 year old desktops” thing isn’t quite as insurmountable as you think.

I mean the most upvoted answer in your link says it often is that insurmountable.
Basically, it’s a huge gamble and a substantial software engineering effort even when you know what you’re doing and source code is available.
It’s not surprising that biologists keep using old machines until they die.
