For //e only
First there was the Apple II 80-Column Text Card, then Apple added 64K to it and called it the Apple II Extended 80-Column Text Card or AIIE 80COL/64K Memory Expansion (#820-0067-B).
Apple II Extended 80-Column Text Card Supplement Apple #031-0496-A or 030-1202-A. Manuals appear to be identical, but published in different countries. The manual you receive may any of these.
This 59 page manual covers how to use the extra memory for more features, storage or as a developer. Used in conjunction with the Apple II 80-Column Text Card Manual.
This supplement is also available with the 80-Column/64K card.
Also pictured are the two versions of the jumper block instructions that came with the card. I only have a couple of these, so will include one only (or a photocopy).
These manuals are in Very Good to Like New condition.
