 True, but what few remember now is that as well as OS/2 1 (80286) and
 OS./2 2 (80386), there was also OS/2 3 (CPU-independent). It was
 initially developed for Intel i810 RISC boxes, the N-10 series, so it
 was renamed OS/2 NT and later Windows NT... and here we are with it
 running on a billion computers. 
 
Just to clarify, the reference to "i810 RISC" should be the i860
("N-10"), their second general-purpose RISC design - versus the 960MX
 from the BiiN project with Siemens in the mid-80s as
their first (?),  
which would become the i960 that was popular in embedded
applications.
