I got my old pascal program running and produced a couple of pictures http://dougs.homeip.net/p1.bmp http://dougs.homeip.net/p2.bmp These are not the best but they do show what i was seeing back in the 80's.
Thanks, Doug. The way the curves behave looks remarkably familiar to the behavior in some of the Mandelbrot orbital images-- what are the iterating functions?
I think I only had 16 colors back then in the VGA mode I was using. I am running XT with a Virtual PC dos partition. I have fractint running in this virtual dos 6.22 and I was able to run my old program, that accessed the video card directly.
It certainly shows that Moore's Law doesn't apply to ideas. Those images are as thought provoking now as they were then. Has your experience with using "Virtual PC" been good? Ie. I assume you were able to use the old compiler under it? ---Hiram
