Over Christmas break I rented a 386 computer with this very configuration.
When the sales rep told me it had a 287 installed I attempted to correct
him by saying that he must mean a *387*, but he said that it did in
fact have a *287* on board because the motherboard was socketed for 
both the 287 and the 387.  When I got the computer home I opened it
up and sure enough, there was the rectangular 287 on the motherboard
and there was a square socket for a 387 to be added as well.  I don't
know how the 386 chip uses the 287--perhaps this can only be done
on a 386sx (I don't remember if this computer was an SX or a DX-20).
The motherboard was a *Mylex* believe it or not!
