I fail to see what Windows NT has to do with anything. OS/2 was originally
16-bit, and ran on the 80286.
I believe the first version or two of Windows NT shipped with x86, Alpha,
PPC, and MIPS hardware support (at least I think those were the 4 listed
architectures). Somewhere I should have a box that says it supports all 4.

>From Wikipedia, development of OS/2 started in 1985, and V1.0 was released
in Decmember of 1987. This pretty much agree's with what I remember from
that timeframe. As V1.0 was text based, and 16-bit, it is possible that a
PDP-11 port could have existed.
Please note, I am not saying that this is OS/2 for the PDP-11, just that
such a port would have been possible in that time frame. I can't see why
such a port would have been done.
On a related note oddly enough at least a partial port of CP/M-68k to the
MicroVAX 2000 exists. I believe one of the list members is the one that has
