Shiva Etherport SE30 + Shiva Access-T

[cannfoddr]

Opened up my other SE30 project today and discovered a Shiva Etherport SE30 card with a Shiva Access-T daughter card.  It looks to be in excellent condition with a D-Connector and what looks like a 10-BaseT connector.  Not done any testing yet - recap comes 1st ofc.

 

Here is the card:

 

and here is the daughter card:

 

There are 4 dip switches all off at the moment on the back of the Access-T card, I suspect they may be to do with switching between the DIN connector and the 10Base-T.  Not found any documentation or drivers yet, assume there must be something in the system folder -> extensions, but I am a total System 7 noob.
