Yup. It took a while but I finaly got one. I might get hold of an even
faster one if I'm lucky. :-)

Sure. Not that I'm that sure that it can get much faster.

Sounds about right. The problem was that when I enabled the instruction cache
with TK4.09 I got some realy "funny" effects on the Nova card. Stuff started
to disapear and text got transparent! In the menues it would just draw text
and no background. Quite funny.... ;-)

Maybe. It's very fast at scrolling and drawing plane text.
