The Mandelbrot generator I posted before runs significantly faster with the new ROM.  It uses a lot of multiplication.  It also depends on SQR, if there were a way I could squeeze a faster version in, the program would probably run twice as fast on the new ROM as on the old one.

I stated porting the Fedora 3D plot program last night to see how much faster it is.  Converting the parameters for different screen heights is a pain, and the oblong pixels on the normal display don't help.
