The old ones need a special video card to work them - probably not easy to get to work with a modern PC or Mac. Andy has a couple of these so he can tell you more. To be fair, the screens themselves look good but are not that special. Once you get past the metal casing and glass contrast screen, they are just a Samsung LCD with all the normal pluses and minuses. They have built in passive speakers which I have never used and as stated before, the power brick is not really up to the job - cheap internal components - mine burned out and I had to get it repaired.
