1. Can Windows 3.0 safely use the math co-processor version of the
   MS C 5.1 version of the floating point libraries?  In some of the
   first versions of Windows (version 0.989), you could only use the
   floating point emulator - something about being unable to save and
   restore the extact state of the co-processor during context switches.

   What's the current scoop on this?

2. What is the MFLOPS rating of a 387 in, say, a 25M Hz model 70?
   What is the MIPS rating of a 25M Hz model 70?

3. I haven't seen much discussion here or in the press about the
   pros and cons of using Windows 3.0 or Presentation Manager.  Are
   they any good books that cover both W3.0 and PM that go into
   this?  I guess I can understand IBM and MS not wanting to position
   one against the other - perhaps that is why there hasn't been much
   of this type of discussion.
