Don't get the 3C905 and 3C509 mixed up though. The 3C905 is a PCI 10/100 
UTP-only card and is supported by pretty much everything. The 3C509 OTOH 
is an ISA 10mb card available in many different combinations of 10Base-2 
and 10Base-T (some also have the 10Base-5 AUI connector) which was also 
supported by pretty much everything. There were also some 3Com PCI cards 
which were 10mb only. Some of those PCI cards even had 10Base-2 (BNC) and 
10Base-5 (AUI) connectors.

I don't recall these cards being NE1000 compatible and I seem to remember 
using 3Com specific packet drivers with them for DOS applications.

I still have quite a few of the 3C905 PCI cards in use and they have been 
extremely reliable. Those that I've taken out of service in the last 
several years have only been to free up the PCI slot for a mutli-port nic.

As far as drivers for the 3C905 go, they are on the HP site or FTP server 
somewhere. HP gobbled up 3Com quite a number of years ago.
