The Compaq Systempro allows you to have both a 387 and a Weitek chip
to be installed on the same 386 CPU.  This is for software compatibility,
because only a few programs, like AutoCAD, use the Weitek chip.  Everything
else uses the 387.  But I suppose a program written specifically for the
Compaq with dual FPU's could keep both of them busy.  The trap
handler might need to be rewritten, because both FPU's use the same
interrupt request line.
