I have written a version of the Mandelbrot Set Generator as featured in
the August '85 Scientific American for the Amiga.  It supports 320x200,
320x400, 640x200, and 640x400 graphics modes, as well as both hold-and-
modify and normal color modes (H.A.M. looks unbelievable!  As good, if
not better than, the pictures in the magazine).  Pictures can be saved,
loaded, sized, zoomed, analyzed, andd displayed using different color
patterns.  Unfortunately, because of the amount of memory required for
the graphics memory and point storage, I had to implement a rudimentary
virtual memory system that could use up to 500K of scratch space on the
disk (after all, there are 256,000 points in a 640x400 display!).  A full
320x200 picture takes around 45 minutes to draw (yes, I am using the FFP
math library).
   As soon as I put some finishing touches on, I plan to upload it to the
net.  I would like to see if there is any interest in it first, though,
because the source is well over 1,000 lines long.

                 Your fractal and mine,
                      Robert French
