To use the Apple IIe Card on a Macintosh LC II, Macintosh LC III, or Performa 400 series running System 7.1 or System 7.1P, you need version 2.2.1 of the Apple IIe Card software. You should upgrade to version 2.2.1 ONLY if you are using System 7.1.
Any error listed "Error Type 1" through an "Error Type 4", an error 10019, a "defective card error", and/or a partial screen in the IIe mode are indicators of the incorrect version of the IIe Card software.
You can purchase a software upgrade kit to upgrade older Apple IIe card software.
Note
----
You can use the Apple IIe Card software version 2.2 with the original Macintosh LC, but it's not required.
