A little more info, it appears to have some foreign writing, which at a
glance appears to be Japanese.  Its english description says

Apple Computer, Inc. 820-0511-A
Apple Ethernet NB Twisted-Pair Card
(C) 1993

Main chip is

Sonic-T(tm)
DO83934AVQB

Two chips by TI, a handful of smaller chips, some discrete devices, a
crystal, and what appears to be the declaration ROM or something.  Seems
like a regular old Sonic card, just with a newer chip rev.

Looking at the info from National Semiconductor, It looks like it should
be backwards-compatible.  I have the strangest suspicion that there's
either an interrupt issue or possibly even just a different memory offset
at work.  Any thoughts on where to begin tracking this one?
