- Hmm.. I wonder why some programes (like screensavers) needs a FPU. Do they calculate something
- in realtime using the FPU or only sometings in the start up?

- What a piece of junk! ;-)

- And telling from the facts it was, eh.. a very stupied question (to say atleast). :-)

-
- Wow, that wa san idea... lets stick to it (BTW. I havn't got any FPU in my bird anyway..).
