I'm afraid the calculator with the code is long dead - but really was a very simple (and very slow) straightforward renderer in whatever the horrible Casio basic programming language was called.

As I recall I first implemented a simple zirpenzky gasket - and then wrote a renderer for the Mandelbrot set. Took only about 5 to 8 hours runtime to do a black and white Mandelbrot...

I was reading a brilliant book at the time, which I've since donated to a school library (and i fear they in turn threw it away) - can't find the exact book now, I think maybe it was called "A walk through modern mathematics" or something like that. Came out in the 90s and had a bit about various chaos theory stuff in it.
