Special Keyboard Characters
Many of the programs written for the Apple //e and //c use
features not available on a standard Apple II Plus. This chapter deals
with some of the differences between the earlier and the more recent
Apple computers and how the Viewmaster 80 can emulate many of
the display features of the //e and //c.
Alternate Keyboard Characters
The Apple ][ and Apple ][ Plus do not have many of the special
character keys available on the Apple //e keyboard. The AW 2
Expander Instructions list some substitute keys you can use within
AppleWorks. Some of these same keys can be used in other
applications. The Viewmaster 80 is internally programmed to
recognize certain unique keyboard command sequences, enabling it
to display these special characters on the screen. The chart, below,
shows the Apple //e keyboard characters and their equivalent Apple
Il keystroke sequence. Since these characters are stored in Read Only
Memory (ROM) on the Viewmaster 80 card, they are only available
when the Viewmaster 80 is active (80 column mode).

You can get a reverse apostrophe by typing Esc ' (apostrophe). There
is no reverse apostrophe on an Apple //e.
