Thanks for the infomration but that had nothing to do with my question. As stated in another post I know about localtalk=
bridge software and that software is not what I want.
I'll try one more time. I'm sorry if it's not very clear.
In the TCP/IP control panel on any mac I have the option of appletalk (Mac IP) as a way to connect to the internet. This=
was very surprising because I don't know of a way to connect to the net via apple talk (Mac ip). It asks for an Ip addr=
ess of the machine (host) and that is it (everything else will be filled in by the 'sever'. I'm currently asking how to =
setup a server that allows other macs to hook up via MacIP (apple talk). I believe this needs Apple IP server or Mac os =
x server software.
My question is, if I can figure out how to server TCP/IP over appletalk (Mac IP) will my newton be able to use this feed=
just like a mac would on my network?
I don't have my newton yet to see whether TCP/IP via appltalk is an option.

LocalTalk Bridge 2.1 Information
The Apple LocalTalk Bridge is an unsupported tool used to share=3D20
LocalTalk-only devices, such as some LaserWriter printers, PowerBook=3D20
notebook computers, or Newton MessagePad communications devices on an=3D20
Ethernet, Infrared, or Token Ring network. With the LocalTalk Bridge, you=3D20
can access an Ethernet, Infrared, or Token Ring network while maintaining a=3D
=3D20
seamless connection to your LocalTalk network. Again, this is an=3D20
unsupported tool and has been provided solely as a convenience. Apple makes=3D
=3D20
no warranty or representation, express or implied, with respect to this=3D20
program, its quality, performance, or fitness for a particular purpose.
System requirements for the LocalTalk Bridge
System software version 7.1 or later.
Either classic AppleTalk networking software or Open Transport version 1.1=3D
=3D20
or later. For machines running Open Transport, version 1.1.2 or later is=3D20
recommended.
Memory requirements:
=3DB7 The LocalTalk Bridge driver requires approximately 70K of RAM to=3D
run.
=3DB7 Open Transport requires a minimum of 5 MB of RAM for computers=3D
with=3D20
68000-family microprocessors or 8 MB of RAM for computers with PowerPC=3D20
microprocessors. Open Transport memory requirements are based on total=3D20
system memory including virtual memory, minus the size of any RAM disk and=3D
=3D20
disk cache you choose.
Hardware Requirements:
=3DB7 The LocalTalk Bridge requires at least a 68020 processor.
=3DB7 Network interfaces to include one LocalTalk port and an alternate=3D
=3D20
interface (Ethernet, Token Ring, or Infrared).
Installing the software
The following installation procedure directs you through both a new=3D20
installation and updating an existing installation of the Apple LocalTalk=3D20
Bridge:
1. Drag the LocalTalk Bridge icon onto your computer's System Folder icon=3D20
and release the mouse button before the System Folder automatically opens.=3D
=3D20
The LocalTalk Bridge will be automatically installed in the Control Panels=3D
=3D20
folder inside your computer's System Folder. If you get a message=3D20
indicating that an older version of the software already exists in this=3D20
location, click Replace.
2. Choose Restart from the Special menu.
When your computer starts up again, the LocalTalk Bridge is installed.
Description
The Apple LocalTalk Bridge is an unsupported control panel that bridges a=3D20
LocalTalk network to another network selected from the Network or AppleTalk=3D
=3D20
control panels. This solution allows for connectivity to higher-speed=3D20
networks (for example, Ethernet, Infrared, or Token Ring) while maintaining=3D
=3D20
the ability to print to LocalTalk-only LaserWriter printers or share files=3D
=3D20
with PowerBook computers that lack high-speed network capabilities.=3D20
Similarly, when connecting to an Ethernet- or Token Ring-only network, the=3D
=3D20
LocalTalk Bridge provides a way for LocalTalk-only PowerBook computers or=3D20
Newton MessagePad communications devices to gain access to network services.
The LocalTalk Bridge features dynamic, user-selectable access modes. When=3D20
access is set to Private, the LocalTalk devices and services--such as=3D20
LaserWriter printers and shared Macintosh volumes--are hidden from users on=3D
=3D20
the Ethernet or Token Ring network, while LocalTalk-only devices retain=3D20
full access to the services on both sides of the network. In contrast, when=3D
=3D20
access is set to Public, all devices are visible from both sides of the=3D20
network.
Known Incompatibilities and Limitations
NOTE: The LocalTalk bridge will not function if a router is detected on the=3D
=3D20
LocalTalk network. The LocalTalk Bridge can only be used on a LocalTalk=3D20
segment that does not already have an active AppleTalk Internet Router,=3D20
LaserWriter Bridge, hardware based router, or another LocalTalk Bridge.
Switching Interfaces
When LocalTalk Bridge 2.1 is installed, switching AppleTalk from one port=3D20
to another may cause a crash. The LocalTalk Bridge should be disabled=3D20
before switching ports.
Availability of Bridged Devices in the Chooser
To ensure that bridged devices are seen or available in the Chooser it is=3D20
important that the Bridging Device (the Macintosh running LocalTalk Bridge)=3D
=3D20
is booted and that the LocalTalk Bridge is loaded prior to booting the=3D20
other machines in the LocalTalk network.
Device Bridging Limitations and Workstation Performance
There is no hard limit imposed by the code on the number of devices that=3D20
can be attached to the LocalTalk segment. However, the number of devices is=3D
=3D20
limited by the LocalTalk network architecture. If the LocalTalk network is=3D
=3D20
properly repeated or bridged, there could be as many as 254 devices=3D20
attached to the LocalTalk side of the bridge.
"Inside AppleTalk, 2nd Edition" states: "The physical characteristics of=3D20
the LocalTalk twisted-pair cable allow it to reliably support a recommended=3D
=3D20
maximum of 32 devices." So, without a bridge or repeater, the maximum limit=3D
=3D20
is 32 devices.
However, 20 is the recommended number of devices recommended when the=3D20
bridge is also being used as a workstation. For more devices than that the=3D
=3D20
Macintosh should run as a stand-alone bridge, because there will not be=3D20
enough computing cycles available to process the user's requests in a=3D20
prompt manner. However, the degree of user requested responsiveness and=3D20
ability of the machine to function as a bridge is a function of the speed=3D20
of the underlying hardware and volume of bridged network traffic.=3D20
Presumably faster machines under lighter network loads could remain more=3D20
responsive to user requests while bridging up to the 32-device limit. High=3D
=3D20
volumes of network traffic can significantly degrade the responsiveness of=3D
=3D20
the bridging machine on even the fastest Macintoshes.
Mac OS 8.5 and Mac OS 8.5.1 Compatibility
The Open Transport 2.0 Read Me - Part 1 states the following:
=3DB7 Apple LocalTalk Bridge 2.1 is compatible with Open Transport.
However, Apple has done only limited testing with Apple LocalTalk Bridge=3D20
under Mac OS 8.5. LocalTalk Bridge 2.1 is not believed to be completely=3D20
compatible with Mac OS 8.5 though no specific incompatibility information=3D20
is available.
Network Assistant performance over LocalTalk bridges
The Apple LocalTalk Bridge can affect the performance of Network Assistant.=3D
=3D20
Performance degrades when transferring data or sharing screens between=3D20
workstations on a LocalTalk network and an Ethernet network.
To improve performance, set up screen sharing and file copying to the=3D20
LocalTalk bridge workstation (and any workstations connected via that=3D20
bridge) separately from the rest of the workstations and use a computer=3D20
connected to an Ethernet network to administer the LocalTalk computers, not=3D
=3D20
vice versa.
