I'd really like to see a picture of it.. Hmm..

Which of these do the slots on your motherboard/card resemble the closest?

1)

2)

3)

4)

Or is it even longer/shorter?

I would have to say it most resembles the middle pic. but the part of the board that connects is larger and more spread out on mine. Same basic configuration tho.
Hate to drive you crazy with this when a picture would make it so much easier.

Okay, what ports do you have on your motherboard out of the following:
PCI


ISA


CNR


Out of the ones you have, which are you trying to connect your modem to?
If it's a long black slot then it's an ISA, in which case your modem (being PCI) won't fit

Have to say it looks most like the first pic. but my slots are white (if that makes a difference).
But the tabs on the modem don't match up with the slots on the board.

When could you get a pic?

DarkLord, sorry for the long delay in responding to your last question.
I should have my camera back next week sometime. In the mean time I'm going to pull the modem out of this computer to see if it fits.
Can't imagine why the other won't fit.
