I think a Xircom will be the solution here. Its just a small device that offers two serial ports and is hooked up to the USB port of Your G3. With this one You not only can use the Newton within OS 9 with all the fancy stuff from that time for the Newton but also within OS X conecting Your 110 to iCal, Mail and others (needs free additional software).
I once tried it with a G3 B&W and it worked like a charme, but I had a MP 2100 (and I'm not sure if it works with NOS 1.x devices within OS X). Maybe I will try it sometime.
So what You have to watch out for is that Griffin iMate and just an old serial cable for Macs. Both pop up from time to time at eBay's. I will have a look on what was the name for the OS X software.

P.S.: The software is called "NewTen" - http://osx.iusethis.com/app/newten
P.P.S.: "Xircom" - I don`t know the regular product name anymore, will have to dig it out. Please note that Griffin´s iMate just provides an ADB port and not a serial. There once were several solutions out there to connect a Newton (mostly 2100 and eMates) to "New World Macs".
