I recently posted a summary about networking between the Mac SE and Unix
machines. Enough new information has come in to make reposting worthwhile.
There seem to be only two systems that let plain old Mac programs transparantly
access files on a remote Unix fileserver:
1. Cayman Systems' Gatorbox
This box lets Mac applications use files from any NFS file server;
it is also a complete superset of the Kinetics FastPath.
Not only does it allow use of TCP/IP protocols on LocalTalk,
but it allows use of AppleTalk protocols on Ethernet, and
translates Apple Filing Protocol requests into NFS requests regardless of
whether they arrive over Ethernet or Appletalk.
Either LocalTalk or Ethernet may be used to connect the Macs to the box;
either thick or thin Ethernet may be specified.
The number of Macs that one Gatorbox can support depends on how often the
Macs need to use the network.
This is a slick box! They built EXACTLY what I was looking for.
Cayman Systems' phone number is (617) 494-1999.
Using LocalTalk: $50 per client + $3500 for the Gatorbox bridge
Using EtherTalk: $600 per client + $3500 for the Gatorbox bridge
2. TOPS, a proprietary network file system developed independantly
and later purchased by Sun; this has been available for some time.
The only Unix box that TOPS currently runs on is the Sun-3.
Either LocalTalk or Ethernet may be used to connect the Macs to the Sun.
TOPS phone number is (800) 445-8677.
TOPS server on Sun ($900 for 1-4 clients, $1600 for 1-16 clients)
TOPS client on Mac ($250 per client)
using LocalTalk: $50 per client + $2000 for the Kinetics Fastpath bridge
using EtherTalk: $600 per client
Another NFS systems, rumored but not currently available, are
3. Peter Honeyman (one of the authors of HoneyDanBer uucp?) led a project
at CITI that put tcp/ip and NFS on Macs, under contract to Apple.
Apple has the software now; it's unclear when if ever they will release it.
UMich was involved in testing CITI's software.
LocalTalk is Apple's 230 kilobit/sec serial networking hardware;
EtherTalk is Ethernet, the standard 10 Megabite/sec networking hardware;
Appletalk is Apple's set of networking protocols;
TCP/IP is a standard networking protocol.
(Although Appletalk is usually used with LocalTalk, and TCP/IP is usually
used with Ethernet, any protocol can concievable run over any hardware.)
NFS is a standard file serving protocol;
Appleshare is Apple's file serving protocol.
There are also systems available that let TCP/IP aware programs communicate
with other machines on an Ethernet.
1. Kinetics sells Ethernet boards for all versions of the Macintosh; it
also sells a TCP/IP (Ethernet) to TCP/IP (LocalTalk) bridge, called
2. NCSA maintains a professional-looking TELNET package for the PC and the Mac
which supports remote login, multiple VT102 emulation, Tek 4014 emulation,
subnetting, and dynamic IP address assignment via RARP.
I think this is shipped with Kinetics equipment.
3. Either Stanford or Columbia maintain something called KIP and CAP
which seems to be another TCP/IP package; this might also be used with
the FastPath or Gatorbox.
4. Phil Karn's KA9Q package is another TCP/IP implementation.
It is free for non-commerical use, and source is available.
Thanks to everybody who sent in corrections.
