Using the //e or //c Auxiliary Memory "Language Card"
                               ...............William M. Reed

From what I have seen in print, I had assumed that the portion of the 80 column "aux memory" that corresponds to the language card is (generally) unavailable for use.  This assumption is only partly true.

In order to access this area ($D000-FFFF, banks 1 and 2) you must switch the ZERO PAGE at the same time.  There seem to be no examples of this in the Apple manual, and very little advice.

The only "tricky" thing was to save the stack pointer (in the old manual supplement) before switching zero pages and language cards.
