Humm; my performa 600 has a 68881 FPU added on the motherboard. The Diimo
accelartor has it's own on the PDS card (a 68882). I wonder if this has some
thing to do with it...

I have just got the 68k FPU source. I notice that the CodeWarrior project
is optimized for the 68881 FPU. But in the project settings, there is no
option for 68882. Another possibility. I will try various re-compiles to
see if I can solve the problem.

I'll do that. But POV-Ray on 68k without an FPU? Ouch.

I have an old G3 which traces quite fast. I went to 68k because the PPC
is in
use by another. It was quite a shock going back to 68k; like walking
through treacle!

Thank you for replying Thorsten.
