Not true -- I often would use AppleTalk instead of Serial with NCU over a
plain old Newton to Mac serial cable before I got an Ethernet card for my
2100 (which is what Brian should get if he as a 2x00 or eMate, by the
way, since I think both his devices are Ethernet capable - the iMac
already has it, and the 3400 may...and it has PCMCIA card slot, so he
could add another card there, if it doesn't have it built-in).

 AppleTalk between two devices over a serial cable works fine. The only
thing you CAN'T do with such a cable is daisy-chain additional LocalTalk
devices. But if you don't have any other devices, a plain old serial
cable does work with NCU (and other devices too.)

Appletalk over a serial cable or Localtalk/PhoneNet cable is much faster
than just plain Serial. (230kbps vs maybe 56k or 120k, I forget the speed)

And Appletalk over Ethernet is HUGELY faster still. Well worth the money.

That's probably the Stealth Serial Port (, I think....),
which put a true serial port in the slot where the B*W G3's modem goes
(replacing the modem, if you had one). A friend of mine has one of those
- he bought it so he could do LocalTalk to his printer and internal file
sharing, since is AT&T @Home Internet connection starting freaking out
his AppleTalk over Ethernet activities all of a sudden (it kept going up
and down and up and down....)
