Though somewhat annoying, the 8MHz Zip Chip is a much more general
performance win than any (even the fastest) FP coprocessor. 

If you think about what /RDY is expected to do, you can see why the
designer of an asynchronous cache-based accelerator would have trouble
justifying it on a cost/benefit basis.
