It is a 201. Docs for the card and the basic firmware are on bitsavers.
I'm trying to locate the manuals for the other (VME,Qbus,and Unibus) versions
if anyone has them.

The optional downloaded TCP stack had an interesting feature that the IP
address was hardwired to the Ethernet adr. Between that, and it having worse
performance than the code running on the main processor, most people ran
the cards in logical link mode.
