>A 486 without a FPU? Sounds broken to me.
I just went through this little shock on another list. Here's what I'm told:
o A 486 DX is a complete chip.
o A 486 SX is a complete chip but with the FPU "disabled". I suppose
that they just erased a couple of critical traces on one of the masks.
Unlike the 386 SX, it has full-width external address and data buses.
o A 487 "coprocessor" is a 486 DX that knows how to disable your 486 SX
completely and take over its work.
It sounds just crazy enough to be true.
