Chaos Calc 2 is my GEM-based Mandelbrot explorer for the Atari ST, written in GFA BASIC 3.5 and compiled. Zoom (almost) into infinity, cycle colours, swap palettes, and save plots as compact Chaos Definition Files or uncompressed Degas pictures.
Shareware. Registration is £5, which unlocks Julia sets, extra CDF saves, colour-cycle direction, and desktop accessories. I received zero registrations, plus one phone call from somebody who wanted to be certain their fiver would get them a floppy disk in return. They never sent any money.
This is the 4 January 1994 shareware release. An earlier build from May 1993 later turned up on DiscMaster.
