For the Apple IIc
Apple IIc Memory Expansion Card, 820-0178, 670-0026. 256K on card, expandable to 1MB. It has been tested and works fine. Includes standoffs.
Requires a ROM 3 or 4 motherboard. Earlier versions do not have the expansion port (located under the keyboard). Last 2 photos are of a motherboard with the memory expansion port, and and earlier one without. This card does NOT work on the IIc Plus.
