Hi, At the moment a extracting all the ROMS of my messagepads. Just for playing around in Leibnitz. I realized that the name of the OS 1 versions is a bit odd. There is an Englisch 1.10, but an German 1.1.00. So the 1.10 is newer? Is there a source about the Newton OS versions. Changelog, etvc? Have an nice Christmas! Cheers Christoph
