Urm, sorry.  That's what I meant.  You may have to dump/view the
content of the ROM, using MacsBug or Slots program.  A copy of Slots
should be found on

On which machine it claims to work doesn't matter.  What matters to
NetBSD "ae" or "sn" driver is what programming model it uses.  NIC
chip and SONIC chip are different enough to need different drivers.
Your card is recognized by the "ae" driver that takes care of NIC
variation, but I have a feeling that yours is a SONIC chip which the
"sn" driver should recognize.

(Is there any relationship between Sonic cards and SONIC chips?)

Before shelling out $$$, I suggest you check out the working status
