IBM 3270 adapter/emulator (I think)
The card has a white sticker which says:
MFG LOC 23
74F3463 ASP
EC:A79301 9051
Printed on the PCB
74F3462 -07 WJH #802 EC A79301A bar code sticker has 62533156538 printed on it
I don't think this is an ethernet card. I think this is a terminal emulator card for connecting to mainframes. I don't have any drivers for it. If you find any e-mail me.
QBMCA seems to support my conclusion
There is a 74F3465 which is called "The IBM 3270 connection". I think that may be the same thing.
Here are some links which provide some information on 3270 technology: (found by doing an altavista search on "ibm 3270")
If you have more information on it email me.
