Ha, on my Amiga (with 32-bit registers) I managed to do fixed-point 
32-bits math, and use the libraries in a clever way, to draw a 320x256 
Mandelbrot set with 32 iterations in about 40 seconds.

It drew from bottom to top, because that way, I could use a slightly 
faster 68000 instruction that decremented a counter until 0.

I considered doing a boundary scan, but that's not at all that trivial 
to do.
