I just got my Keyspan serial adapter today. Of course, I had to do a test-drive with NewtSync, and it worked! I am so happy and pleased with your software. However, it would great if you could somehow implement the options of Apple's Newton Connection Utilities into this App (like, Use keyboard to type stuff in on the Newt, Backup, Restore, import, install package, and ESPECIALLY- EXPORT!!!) otherwise, I'd like to bring this to your attention- please set the system requirements for the newton, to Newton OS 2.X- because IT DOES WORK on Newton OS 2.0 (It did on my Newt!- an old MP 130). Leaving that at Newton OS 2.1 could give people the wrong impression that their older Newton OS 2.0 devices (such as the MP 120 or the MP 130) are not supportted by this app, which, in fact, they actually are. Otherwise, keep on chugging away at this app. It's great. I look forward to it having added features sometime in the future (so I dont have to boot in 9 just to use NCU to export something off my Newt without having it sync the entire thing!)
