Well, it sounds like there is some type of issue with the Apple IIe. Is there some type of diagnostic's hardware/software for the Apple IIe to check the card slots? Since you have literally replaced everything (except the Apple IIe) with known good parts (which were verified to work with another Apple IIe), and the WiModem232 and cable works with the Apple IIc, this really would have to be some hardware quirk in your particular Apple IIe. It would be good to know what that might be.
