I don't have it now to check, but I'm sure my IIfx was indeed a DA-15.
I still have the DA15-to-something-sensible adaptor. Mine did also have
a network card, but the presentation was 10baseT. If it has 4-40
screws, it's video; if it's slide-lock, it's Ethernet.
Then I would
only need to find an AUI to RJ-45 doodad
which is skinny enough to fit into the recessed ports on the IIfx. I
have an AUI thingy now, but it's too fat to reach the db-15 connector
on the network card.

Are you sure that's an AUI connection? I would expect a Mac of that
vintage to have a DA-15 for video but not Ethernet. Does it have 4-40
screwposts or stud-heads to receive a slide-lock clip? I've never
worked with a IIfx, but I would expect it to need a NuBus Ethernet
card. If it really is an AUI, what was also common in the
day was an AUI
cable to the transceiver. I've seen plenty of heavy-duty ones from
back in the 10Base2 days and lots of light-grade 1m to 2m-long thinner
cables with molded black plastic ends that look suitable for
office/desktop use.
Companies like Allied Telesyn made two types of mini transceiver, there
was the normal one (AT-210T) that was a more-or-less rectangular box
with a slide-lock DA15 and rounded corners which works on most things
because they don't have stupid slim recesses, and there was the
"micro-transceiver" (AT-210TS) which is very slightly longer, but
stepped so the end with the DA15 is only as thick as it needs to be to
accommodate the connector, and hence fits Macs -- which is what it was
specially designed for. Google will find you pictures.
The AUI drop cables are actually specified to be thick blue things
(normally with diecast metal connectors) for normal grade, and thinner
beige things (with beige or black plastic-covered connectors for what is
officially called "office grade" and restricted to short lengths. I was
just about to put one or two (office grade) on eBay, if anyone needs one.
