Some motherboards (my budget 386-40, for example) have a math co-processor
socket that will accept either a 387 or a Weitek floating-point accelerator.
The 387 leaves two sides of holes empty, but which are filled by the pins of
the Weitek.

Motherboards typically are designed to accept only one type of 387 chip; it
is simpler.  The SX829 might be a version or date code (someone please
correct me).

If your 386 CPU is also running at 16 MHz, I'd say stick with it.
