I think this thread has gotten way off base. Just because something is possible, doesn't mean it's a good idea. The peripheral 68882 was really just a hack so you could use a math copro without an 020. The only adapters I know of are zorro-2 (microbotics starboard comes to mind) and would have really high latencies. I would guess that it would run 1/4 of the speed in peripheral mode. But, the really big problem is that there is nearly NO software that takes advantage of a peripheral math copro. I think only v1.0 of real3d supports it. Lightwave, vistapro, turbosilver, etc do not support a peripheral math copro.
The only way an 882 could reach 100mhz would be with liquid nitrogen...
