According to some very sketchy Intel documentation, the 8087 does work
with the 80186/80188, but because of differences in the bus timing, requires
the use of the 82188 interface chip to "complete HOLD/HLDA bus protocol
conversion to RQ/GT, synchronizes ready and provides local bus control
signals."  I asked the representative at the Intel seminar whether there
was a hardware reference manual (we were given the programming reference
manual which referred to the hardware manual) and his response was that
he had not seen one ... it is probably in press.

I guess the answer to the question on whether the 8087 will work in the
socket provided by Tandy depends on the design.  My guess is that Intel
will not be coming out with the 80187 if they are providing wiring diagrams
with the 8087 in their seminars.
