The following information was sent to me by email on AOL from: anon@anon.com
remail service last month. I thought it might provide some useful insights for
those that want to try and set up a IIgs - Mac - PC Network, so I'm providing it
here without any method of knowing if it might work or not.
----------------------------------------------------------------------------------
Using a Network Configuration for the IIgs

The following networking scheme is of interest to try. The goal is to have one
or more Apple IIgs' networked to a Pentium 200 or higher with the ability of
adding a Macintosh when necessary. First, some outline on the problems about
making this network configuration operational. The current networking standard
among small computer networks is EtherNet, a fast and reliable method of
transferring data from one computer to another. Back in the early 1990's Apple
had a release quality ethernet adapter for the Apple II series of computers
called the Apple II Ethernet Card. Very late Beta copies of the Apple IIgs
System 6.0.1 had the drivers and other needed applications to support the Apple
II Ethernet Card. But, Apple decided, at the final stages, to scrap the ethernet
adapter project. Currently, there's no direct ethernet adapter for any Apple II
series except for the few prototype EtherNet cards that a few individuals
managed to aquire. There are a few options noted below to work around this
problem, see below;

Macintosh Use Information

1. Connect your IIgs to the Mac via a serial cable by using the built in
AppleShare utilities of both computers.

2. Connect your Macintosh to your PC via Ethernet. You see, the Mac acts as a
bridge between the PC and the IIgs.

The Serial to Ethernet Adapter

1. Purchase a Serial to Ethernet adapter such as the Shiva FastPath or
the EtherPrint 

2. Purchase PC MacLAN from Miramar Systems.

PC MacLAN allows a Windows 95 or NT system to act as an AppleTalk server over
LocalTalk or EtherNet networks. The IIgs running GS/OS 6.0.1 is able to connect
to AppleTalk shared volumes At this point, with the Ethernet to Serial adapter
and PC MacLAN properly installed and configured, you should be able to connect
to any shared volumes on the Windows 95 or NT computer with the Apple IIgs and
the System 6.0.1 AppleTalk utilities.


I now have PC MacLAN installed and working with my EtherNet card and EtherPrint
serial/ethernet router. I can mount the shared volumes from PC MacLAN with ease
successfully on Macintosh computers, but attempting to do so on the Apple IIgs
causes a complete hang of the system. I'm currently trying to track down this
problem and will post details as they become available.

The problems with the IIgs not working on the network have stil not been
resolved. One possibility I am looking at is that I need to update the ROM in my
EtherPrint, because other EtherPrint versions have been tested and work fine
with this setup.

I have yet to acquire another EtherPrint or newer ROM and have decided to give
up on using the EtherPrint with the IIgs. The current network is as follows:

Computers on the Network:

Pentium 200 system running Windows 98 with an ISA ethernet adapter. Macintosh
PowerBook Duo 2300 running MacOS 7.5.5 w/ an ethernet dock Macintosh Quadra 605
running System 7.5.5 Apple IIgs running System 6.0.1 NeXTStation running
NeXTStep 3.3 User...

Network Hardware: Kingston EtheRx workgroup hub 
                  Dayna EtherPrint-T Ethernet->LocalTalk router 

The Pentium 200 acts as the central AppleTalk server because it has the most
storage of any computer. The Pentium, the Duo 2300, and the EtherPrint-T all
connect to the workgroup hub. The Quadra 605 is connected, via LocalTalk, to the
EtherPrint-T and the Apple IIgs is connected, via LocalTalk, to the Duo 2300
which runs Apple's LocalTalk Bridge software.

The next step is to get all, or most, of these machines to share a single
connection to the internet. Soon to be added to the network is a NeXTStation and
a Sparc 1 system.

The NeXTStation is now on the network and connected to the Pentium 200 via
TCP/IP. The next priority is sharing an internet connection with as many
machines as possible.

I've now installed and configured SyGate, a Windows proxy networking
application. So, now other TCP/IP equipped computers here may share the single
internet connection that is established on my PC. At current, the NeXTSTation
and the PowerBook Duo 2300 are working quite flawlessly with SyGate. The next
step is to get the Apple IIgs tied into all of this. There are two options, at
this point. The first is to wait for Richard Bennett to implement MacIP (TCP/IP
over LocalTalk) into Marinetti. Download the current release of Marinetti, from
this url: 

http://www.apple2.org/marinetti/


Another option would be to set up a NeXTStation as a SLIP or PPP server. As PPP
is included with Marinetti. So, with it - you could connect the IIgs to the
NeXTStation with a serial cable.
