Either way, though, NT on Alpha was very much a "first generation Alphas" thing, and the ES family is a "last generation Alphas" thing. I'd be shocked if it even came close to booting on a 21264-class processor. ...which means I'm utterly shocked to hear of any DS20 support at all. Well I learned something today. ;) You know DEC, they loved supporting legacy products almost into oblivion. Yes, for GOOD products...NT on Alpha was an utter failure by every metric. I mean, when did they stop officially supporting PDP themselves? Supporting I don't know, but the last PDP-11 to roll off the assembly line did so on 9/30/1996.
