80686? Do you mean the Pentium Pro? If so, unless you are counting the supporting chipset (440FX, BTW) or the x2/x4 server configurations (where it is its own coprocessor), then I know of no coprocessors. When I think of coprocessors, I think of the separate floating point units, but the Pentium Pro had an embedded floating point unit, so that doesn't apply.

There is no floating point coprocessor for the Pentium Pro; support for floating point operations is built right into these processors.
