I have the same thing to say as dibenga- I've been using this under Jaguar to install crap onto my old Newton MP 130 using a Keyspan Twin Serial Adapter. I've eventually learned how to install the packages onto my newt, but the same is true here. The app NEEDS a reset or stop function- I find myself having to Force-Quit the app several times because I had a bad sync (at first, the application doesn't respond, so I have to try at least 2 or 3 times at it.) Also, how about PREFERENCES? So it WILL finally remember my last serial driver selection- cu.USA281P2.2? Otherwise, ROCK ON! Thanks for keeping the Newton Pride Alive, especially under OS X! (although I still have to boot into 9 if I wish to backup, use the keyboard to type on the thing, or export stuff off of my Newton through the Newton Connection Utilities.) As I said to the creator/s of NewtSync (another OS X newt app that syncs Newts with your iCal calendars and address books), Keep chugging away. These Newton Apps are really wonderful.
