FWIW: I have two different styles of AUI-to-UTP converters. One is the block style
that's been mentioned here. The other has a short lead terminated in a DB15. I
don't have a IIfx so I can't test the hypothesis, but if it's similar to the
IIsi I think it should fit. -- Ian
PS: where did I get those transceivers? eBay....

I was able to find some schematics for the special iifx terminator.
it was just a few extra filter caps. I had planned to make one, but
hadn't got to it yet. I managed to find a real one first.
the iifx has a nubus ethernet card with a 10base2 and aui connector
but no rj45. the tranceiver I have is too fat to fit into the slot in
the back of the machine. so it can't reach the db15.
i've been meaning to setup a linux box so maybe i'll try the emulator
route with that.

I tried to look that up and found it easy to see that the IIfx needed
something odd (I couldn't find specifics), so well done there. It
would be interesting to get the details to see where Apple went off
the rails from the SCSI spec.

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.
