These days I've been coming across a lot of people who've purchased used MINDSTORMS sets from the RCX era, only to find they didn't come with a CD. And in order to use the set, assuming that using an alternate programming language is not an option, the buyer can either Buy a CD off Bricklink, or find a place to download the software.
While CDs aren't overly expensive, they're going to become harder to come by as time goes on, and being able to download the software is preferable since it's almost instant and doesn't cost money. LEGO technical support representatives have stated over and over again that they don't care about people copying and downloading their old software, so downloading their old software is perfectly legal.
Does anyone know a reliable place to download the software for the Robotics Invention System 1.0, 1.5, and 2.0? CD images are preferable, but working stand-alone installers are valid as well. Extra points to anyone who can also provide a place to download the software for the Vision Command, Ultimate Builders Set, Exploration Mars, Extreme Creatures, and Robo-Sports expansion packs. And super extra special points if someone knows where to get an iso for the Windows XP-specific Vision Command software and the Robotics Invention System promotional CD.
