Yeah, I think the only commercial OEM releases of NT that got sold were x86 and Alpha, though there was support for a handful of specific MIPS and PPC machines, I don't think there were any OEM sales of them with it. I do know that only x86 and Alpha had all the service packs released. There were also at one time internal MS builds on Sparc, but that didn't last long. Alpha did have some pre-release builds of windows 2000 that went out, but there was no final release. A fun fact is that because of where he worked at the time was a DEC shop, the creator of PuTTY originally created it because he got an alpha windows machine and there was no compatible terminal emulator for alpha NT. He supported alpha builds well into the 2000s and IIRC only dropped it as the machine he was using still for builds finally died.
