I have updated the board layout and interface somewhat to match
recommendations of the local Crystal FAE. Also changed the connector to a
2x13 header so it will accept a cable interface.
My board will probably support Gary's software. I did my s/w in HiTech C -
it's easier and besides this will allow me to borrow Unix/Linux/whatever
source to extend it to more than just a ping-able address very easily.

I just wish there was a 10Base2 version available of this, didn't see
one (did look but it's been a while.) The home LAN here is mainly
10Base2 (With 2 hubs), for rented/leased situations it seems to work
better to run 1 coax than having 15 RJ45 cables strung down the side of
the hallway <G> Guess I just need to move into a warehouse so I can do
things the way I want to <G>

The Crystal Ethernet chip used in the design can also provide an AUI interface.
You could connect any AUI-.... transceiver: UTP, Coax, fiber, etc....

Well, if you implement the AUI port on the board, you can make an
AUI-to-BNC adapter that will do what you want.

Thanks to you & Arjen both <G> I hadn't thought of that (Very good
thought!), though AUI-10Base2 conversion might be pricey (Haven't
designed one of those yet - always someone else's department <G>), that
would work well - might be a net savings using Coax instead of hubs, if
you had 50 or 60 Ethernet boards in the house, too!

Well, it's a pulse transformer, a power converter module and an 8392
chip, plus some chaff. Some cards I've seen have all this on a daughter
module, suggesting that at least some time in history, it was available/
economic.

You're welcome ;-)

AUI-10Base2 transceivers are off-the-shelf little boxes. Powered via the AUI
connector.
They cost anything between say $20 to $50 depending on the source.
Any good IT/datacom/network/cabletools distributor will have them (cheap).
Your local PC shop might have, too... but chances are they'd be expensive
there; could get lucky though.
