Today I got around to using a fix that allows our old CHAOS software to run, I think, on every platform. See my CHAOS page for full details, and for the free downloads. Thanks to “Torbjørn Pettersen” and “Jac” for having advised me.
Summarizing some of that that page says, CHAOS is a shareware release of James Gleick’s CHAOS:the Software. We provide both the complete executable and the source code for the 1990 Autodesk release based on the wonderful book Chaos, by James Gleick.
The software was written by Josh Gordon, Rudy Rucker and John Walker for Autodesk, Inc., with Josh Gordon doing the lion’s share of the programming work. It is our hope that this shareware release will allow educators, students and dabblers to freely use our software. Great for classroom use or individual exploration.
CHAOS can presently be run, using the free DOSBox ware, under Windows, Linux, Mac OS X, and other platforms.
CHAOS has six modules.
1. MANDEL. A fast Mandelbrot set program, incorporating: quadratic and cubic Mandelbrots, various fill patterns, quadratic and cubic Julias, and the gnarly "cubic Mandelbrot catalog" set that I call the Rudy set. For more up-to-date info on these fractals, you can also look at my 2010 formula files and parameter files for the commercial Ultra Fractal software as described on mys blog post, “The Rudy Set as the ultimate Cubic Mandelbrot.”
2. MAGNETS… A Pendulum and Magnets program showing chaotic physical motion.
3. ATTRACT. A Strange Attractors program showing some of the Hall of Famers as the Lorenz Attractor, the Logistic Map, the Yorke Attractor, the Henon Attractor, etc.
4. GAME. A "Chaos Game", which is a Barnsley Fractals program showing Iterated Function System fractals such as the famous "fern".
5. FORGE. A "Fractal Forgeries" program that shows mountain ranges based on random fractals.
6. TOY. A "Toy Universes" program that shows some cellular automata.

It does work under OS X, when executed inside DOSbox. DOSbox provides some hotkeys that are useful for changing the emulation timing, since some older games relied on slower machines in order to render properly. By default, DOSbox runs significantly slower than your actual hardware is capable of. Some of the CHAOS software will benefit from turning the speed up (e.g. MANDEL).

Hello! Your article was re-posted (via RSS) into Buzz, my favorite place to learn new things. Thank you for sharing this with everyone!

ok thats really cool…. yet dont forget the Chaos Continuum…. http://en.wikipedia.org/wiki/The_C.H.A.O.S._Continuum

It’s pretty amazing seeing software I wrote on a 386 DOS box, 21 years ago, running on OSX Lion… Hey Rudy, what year did we start working on this? Did we start in ’89 or ’90?

Josh, good to hear from you. I’m glad you’re using the DOSBox Chaos fix. Yes, Chaos is a wonderful program still. I believe we worked on Chaos all through 1989 and 1990, and it shipped in 1991.
You once remarked that there was an Easter egg type key code for making the Chaos Mandelbrot run in higher rez, but I don’t know what it was, if I ever knew. In any case, I was recently playing with some superzoomed versions of our more exotic higher-order Mandelbrot-type sets using Ultrafractal, I posted a lot about that on my blog at http://www.rudyrucker.com/blog/2010/04/02/the-rudy-set-fractal/
Would be great to get together and catch up sometime, send me an email if you like.

I thought ya’ll would appreciate this:
I was just cleaning out my desk, and found my old chaos disks, and was pondering pitching them in the bin. I thought this software was great, and expected more stuff like this from Autodesk, et al. But alas, twas not to be. Had a lot of fun with this software. It drove me to build and tune faster boxes, trying to get better renderings. Nice work!
Anyway, just for fun:
