>> 4) Do I need a different coprocessor socket for Weitec 80387 chips?

The Weitec is NOT a clone of the 80387. There are a couple of versions
of the Weitec for 386s. On is a chip the other is a chipset on a card.
Both require a socket for the Weitec and will not work in the 80387
socket.
    The Weitecs are not compatible with the 80387's nor do they claim
be. The Weitec is in a different league from the 387s and cost a few
hundred $'s more. It is a very high performance math coprocessor and
is generally used for VERY intensive number calculations.
    A program that detects the 387 and uses it if present will not use
the Weitec unless it is specificly designed to also work with the
Weitec.
    The other questions I will leave for others.
