Last time I saw one was a workstation with a 1GHz Alpha processor (yes, so far ahead of time, that's when Pentium was introduced), on a Microsoft gig in 1995, running Windows NT. And then it got nowhere, because most of the DEC's OS/architecture team were hired to make NT actually work. We can say that the ideas that DEC was pushing won big time, too bad for DEC who didn't have the money to keep them.
