Message-ID: <[EMAIL PROTECTED]>
There's a port on the Quadra 700 which I have not been able to identify.
It has an icon that looks like this:
<...>

but doesn't look like a standard RJ45 Ethernet port. It has about seven pins
on the top and on the bottom of the connector.
What does it do?
It is the ethernet port.  As you may know, ethernet used a variety of 
possible cabling schemes back when.   There was thicknet, thinnet 
(forms of coaxial cable) and unshielded twisted pair (UTP, AKA 
10baseT).

Because you didn't know what kind of cabling a place would be in use, 
it was difficult to build ethernet into a computer and be certain 
that it would be compatible.   So the industry standard solution was 
an AUI port.  This is a DB15 port to which the appropriate 
transceiver could be attached, which would convert the AUI port into 
thicknet, thinnet or UTP.

When Apple started building in ethernet they created a new port 
called an AAUI (Apple AUI) which has the virtue of being smaller than 
an AUI port and the other virtue that it is not identical to Apple's 
video port which also uses a DB15.

That funny little port you're looking at is an AAUI port.   To 
convert it to UTP, which I assume would be your goal, you would need 
a transceiver.   They were made by the usual network equipment 
suspects, Apple, Asante, Dayna, Farralon, etc.   Back when, they cost 
about $70.  These days you should be able to get them for under $5 on 
Ebay plus shipping.

Some ethernet cards were also made with AAUI ports and many of the 
early cards for the Mac included an AUI port with the DB15 connector. 
One of Asante's NuBus cards has a BNC, RJ45 and AUI port all on the 
same card.  Apple's LC slot ethernet card has an AAUI port and 
requires a transceiver.

The Asante transceivers often show up on Ebay under the title Asante 
Friendly-Net Transceiver or something like that.

Ethernet, you need a dongle to make it a standard RJ45 port.
