Technically, RIS is the "entire" set, meaning the RCX, the software, and all 700+ lego pieces (plus manual, box, etc.). I doubt that there are version 1.5 lego pieces about to be released, so clearly they could release version 1.5 of RIS without (...) (25 years ago, 2-Jul-99, to lugnet.robotics)

(...) You know, I think I'm starting to get nervous about this 1.5 business. Let's say they do happen to ship a 1.0->1.5 software compatability upgrade.

(...) It has to be reversible from the RCX brick's point of view, since there is no hardware on the RCX to forcibly reprogram its ROM. Perhaps on the PC side it is not reversible, but there is always the uninstall new, reinstall old process, which I (...) (25 years ago, 29-Jul-99, to lugnet.robotics)
