Subject: Need to get Ethernet Address & card type directly from 3Com cards

I need some information about the innards of a few 3Com Ethernet cards,
specifically the EtherLink II (3C503 - IBM PC Bus), EtherLink Plus
(3C505 - IBM PC Bus), EtherLink/MC (3C523 - IBM MicroChannel Bus), and
the EtherLink/NB (3C543 - Apple Macintosh Bus).

What I need to do is create a (hopefully) simple program that, when
run on the PC in which the card resides, will return the card's type
and Ethernet address, either to stdout or, optionally, append it to a
file.

I need to know (I think), which port on the card (e.g., base port + 3)
to send what command(s) (e.g., 0x8c), so the card will return its type and
six-byte Ethernet address from (possibly) a port (e.g., base port + 2).

Can anyone help?  Even if you know the answer for only one of the cards,
please either post or email.  If there's enough interest, I will summarize.
Please note:  I have directed Followup-To: comp.dcom.lans.
