3Com has a 3C589 FAQ. You can pick up the lastest 3C589 adapter software package from their latest drivers ftp directory. It's a good idea to fetch 3C589N.EXE, unpack it and then delete everything except INSTALL.EXE. Having a copy of this on is handy if you need to change the IRQ or want to run diagnostics on your interface.
I run my 3C589 at:
IRQ I/O addr 9 0x3a0
Note that the 3Com web pages had not be updated to reflect the "C" revision of the product at time this was written.
Also, 3Com apparently shipped some 3C589C's that report the wrong adapter id.
Extra dongles are available from most of the mail order computer stores. Ask for the following part numbers:
The twisted pair dongles are only about $20 but I believe the combos are a lot more expensive.

Here's the Linux Alpha Test 3C589 Linux Device Driver page. It's by the driver's author, Donald Becker, and has detailed instructions on how to get and install the driver under Linux.
Note that source for the BSD/OS driver is not available due to
licensing restrictions imposed by Xircom. For this reason, I do not
recommend buying this device. (Not having source prevented me from
fixing three annoying bugs I discovered while using it.)
You can pick up the Windows 95 driver directly from IBM.
If you want to make your own ethernet cables, this Telco Wiring Chart can be helpful.
