Tell me about the display car dyou have, how much memory there?

Trimming is done, for one thing. Really, the FDM takes a very small amount
of computation time. Most of the time is spent in the display routines,
IIRC.

Do you have some particular examples?

This is a non-issue, as far as I am concerned. Like I said, these
calculations have a very small impact on the program.

The same thing was true of my machine, which was less powerful than yours.
My problem, I think, was that I had only 8 MB of video RAM.
