Don't forget that the PC Transporter uses an NEC V30 processor, which
has additional instructions that are also available in the 80186 (and
later family members).  This may be sufficient to allow Win 3.x to run
in standard mode.  (I haven't tried myself, so I don't know the answer
either way.)

I've encountered other software (such as 4DOS) which claim to require an
80286, but which also work on an 80186, or an NEC V20 or V30.
