I have been fighting with this for hours and decided to finally just make a post and see if anyone has ideas. I recently acquired a MacCon SE/30 ethernet card. Upon installing it in my SE/30, the EtherTalk installer does not recognize it as an option. The MacCon's green light is steady on when the SE/30 is powered on. I've tried reinstalling System 7 and re-seating the card a few times with no resolution in sight.
