Looking at the 8087, 80287, and 80387 data sheets indicates that it is not
possible to do this over the ISA bus. However, I see no reason from a
system-level standpoint why an adapter which plugs into the CPU socket
would not work. The problem is trying to find a way to package-up such a
beast so that it plugs into several different systems; I think that scared
off potential manufacturers.
