I got some info from a friend @ Intel on this one, although it seemd a bit 
strange. The 486SX uses the same mask as the 486DX with the coprocessor 
connection traces cut. I don't know about the pinout but one would assume that
Intel wouldn't make the DX and SX pin compatable. The suggested list price
for a 486SX and a 487SX combined is not less expensive than the cost of a
486DX. One has to ask, why would anyone who wants an FPU buy the SX version?
You get the same thing with the added overhead of interchip communication.
