I saw one on eBay and I'm seriously considering it. I've found nothing online about using them in Linux, but I'm willing to give it a shot. I'd wager it shows up as a big pile of USB endpoints connected to a hub or somesuch, might be interesting to see what you can get working.
Quite a few of the keys have awkward action with excess stiction. Not great for programming (and indeed many Bloomberg programmers used other keyboards when that one was current).
