Did you know that the 'NT' in Windows NT stood for "Nine Ten"?
The intended core platform for the OS was the then-expected Intel i910 RISC processor, which was to be the rebranded moniker for the i860 that can be found in the wild. *
It never came to be due to the i860s terrible handling of context switching -- a capability that a CPU for a multitasking, multiuser workstation OS must be able to do _very_efficiently_. The i860 wasn't.

*** EDIT: Several have pointed to sources indicating differently that NT stood for N10, which was the codename for the i860, so -- N10, N-Ten > NT.
