I recently installed an airport extreme network, which works fine. I would like to include an older eMac which currently has no card installed. From reading a couple of posts it seems that the nature of the eMac determines which card I should add. The Apple site has a list of serial numbers that should tell me which card to use, but the number on my machine ends QQH, which is not on the list. Does anyone know which card should be installed in this machine?
