Do all 486 mobos have room for two processors?

I cracked open my old 486 the other day, and I was taking it apart when I noticed that there was room for 2 processors. I never knew that the 486 had a dual processor motherboard.

Or, more likely an Intel Overdrive upgrade socket.
You would leave your old CPU unused in there and make use of the new one.
Sick, I know, but true.
The 486DX had the math coprocessors built in.
The one's that passed only the CPU core inspection were sold as 486SX's with the math coprocessor disabled.
Therefore, I don't think it's designed with the ability for an external math coprocessor.

The 80487 math co-processor was a fully functional 486DX CPU. When you installed this "addon" it simply disabled the 486SX processor.

Indeed, Intel got a lot of negative press about that when it was first revealed.
