[comp.sys.mac] How to put >32 devices on a LocalTalk network

ajq@mace.cc.purdue.edu (John O'Malley) (04/25/89)

Some time ago, I posted a note asking for advice on how to put more than
32 devices on a LocalTalk network.  Here's a summary of the responses I
received.

The problem is that there is a limit of 32 devices per nodename.  To go with
more than that number of nodes, you need to add another zone.  There are
various ways that this can be done:  you can use a Hayes InterBridge
(overkill), a Shiva NetBridge, some type of Ethernet bridge (also 
overkill, unless the Ethernet is already in place), or a StarController
from Farallon (good for connecting up to six nets).  The NetBridge sounds
like the best bet.

Note that the 32 device limit includes networked printers, like the
LaserWriters and AppleTalk Imagewriters.  These count as a device as well.

I have a Cayman GatorBox up and running appleshare-NFS on our network,
and its *nice*.  No longer a need for Aufs servers...nothing. The box
mounts your home directory file systems just as it would any NFS client, only
now it acts as a Mac external drive for saving/launching mac applications.
If these were around 3 years ago we would have 22 Gator Boxes instead of 
Kinetics Boxes!  I have not been able to get NCSA Telnet/MacIP to work
*correctly* yet...but I am confident.

The way we solved the problem of networking the macs in >32 mac lab was by
using a Hayes InterBridge.  This does not require creating separate zones -
only separate networks.  Zones are little more than a convenient fiction
maintained in routing tables - it's up to you whether you make the networks
separate zones or not.

Hello,

I'm not sure who to contact but I thought this group  might be a good choice.
I recently purchased a Radius FPD and a Radius 16MHz accelerator without 
an FPU, now I wish to purchase an FPU. Both the accelerator and the display
card were installed by a Radius dealer, but now I would like to save some 
money and install the FPU myself. I have limited experience with the inside 
of a MAC (SIMM installation) and would appreciate any information. 
    
                                                  Thanks,
                                                  Ron Bannon
