Re: Not the 2nd 64 Windows

NT 4 was only ever 32 bit, and that was all that ever ran on the powerpc, mips and alpha. There were 64 bit development work on the alpha, but it was canceled before release, so only itanium got 64 bit windows released initially to be joined by x86 later, and eventually arm.

As for being portable, well maybe for Microsoft code, but it only works on little endian, which certainly prevents some CPU targets from ever running windows. Only the fact powerpc, mips and arm can run both ways allowed windows to be ported to them, since they always run them in little endian mode for windows. Alpha and x86 of course were only ever little endian. Motorola 68k of course would never have a had a chance to run windows.
