- It will take advantage of the old FPU on the IIci.

-
- No! it turns out another disadvantage of the IIvx's accelerator slot is
- that it can't talk to the FPU on the motherboard. If you put a
- PowerCache in a IIvx, you'll have to get one with an FPU because you'll lose
- the one on the motherboard (I just found this out from DayStar). The same
- goes for the cache (except that all PowerCaches have built-in caches, of
- course).

- > Is a slower FPU better than none at all?
-
- Yes, MUCH better if you run certain apps that make use of the FPU. For
- most apps, it doesn't matter whether or not you have an FPU at all
- because they don't use it.
