Re: The game is up Microsoft - your code is crap!
He lists a couple of similarities between VMS and NT, but he doesn't list how different these superficial similarities are under the hood (e.g. VMS has four process modes, NT just two) or whether the concepts behind these similarities are also present in other OSes of that time, just implemented more or less differently. In other words, common OS design concepts.
And just like there is stuff from RSX and other DEC OSes in VMS, PRISM will have had a recognisable VMS hallmark, with NT again being PRISM-influenced.
