can any one identify this component

I got a card from ebay recently for apple II computer. Although seller
claimed it is a Ethernet card for networking, i have no information
about the card. So I am trying to go by the components to understand
the functionality of the card. But i am stuck with a custom made IC.
It would be great if someone can comment on it or have a datasheet.

IC is in the right-middle position of the card.
any comment is grately appreciated.

It seems to be missing an ethernet connector.

No, there's a right-angle phono connector over on the left side about
halfway up, that could conceivably go to an external BNC for thinwire
Ethernet.

You might try this in comp.dcom.lans.ethernet

There are no markings on the board?

I see 2 interesting things:

(1) Just to the right of the "Innovations in Computing" chip is an RCA phono
jack -- right? Someone's idea of a network connector? What is it connected
to?

(2) It would be very interesting to read the ROM chip. Does the label on it
say SCNet or SONet?

Did Thinwire Ethernet exist when Apple II was around. I remember the
Ethernet cable at that time as being as thick as your thumb and you were
limited to one connection per XXX/meters. We had a bridge which
connected our AppleTalk LAN to the Ethernet LAN. At that time we had
about 3000 Macs (1 Meg RAM each, no less) connected with dozens of
bridges. Yeah, we were a BIG organization with about 3500 employees,
mostly engineers.

The BOSS came in one day, put a Mac on the desk of the IT guy and said,
"Network the damn things. They can do what no IBM PC can." And at that
time he was correct.

Maybe this is a very early version of Appletalk.

If it really was an Ethernet card, it should have an Ethernet MAC
Address somewhere on the card. I don't see one in the pic in your link,
above.

Maybe it's in the EPROM.

That's possible but they used to mark it externally for convenience.
Another thing that I noticed was the big DIPSwitch. I can't remember
ever seeing an Etherhet card with a DIPswitch. But then I can't
remember ever seeing an Ethernet card for an Apple. I know they had the
other AppleTalk, etc cards, but not a real 10Base2 card.

The connector on the right looks odd. Someone mentioned that it looked
like an RCA connector. But it looks like it might have been a BNC, but
part of it got broken off.

You could try your question in alt.folklore.computers - those folks know a
lot of old stuff.
