I don't know how much of a help this is, but all three cards come with a
diagnostic disc which will give you the address information IF you know
the interupt, dma and base i/o address jumper settings on the card.

For the 3C501 the program is 3C501.EXE, and the syntax is

3C501 I# D# B#

Where # is the number corresponding to the card's jumper settings,
I=Interupt D=DMA B=I/O Base Memory address

For the 3C505, the syntax is similar, just add a hyphen before each
parameter:

3C505 -I# -D# -B#

The 3C503 has an intelligent diagnostics routine which tells you
the jumper settings, as well as the address when you run 3C503.EXE.

Except for the I/O Base memory address, the jumpers on the card are
clearly labeled and intuitive. The memory jumpers need the manual's
table to be decoded, but most people leave them at the default setting.

Defaults:

DMA 1
INT 3
I/O 300
