        apple2 - Apple ][ display emulator


        apple2  [-display host:display.screen] [-foreground color] [-background
        color] [-window] [-root] [-mono] [-install] [-visual visual]  [-program
        command  to  run]  [-basic]  [-slideshow]  [-text] [-meta] [-esc] [-bs]
        [-del] [-fast] [-fps]


        The apple2 program simulates an original Apple ][ Plus computer in  all
        its 1979 glory. It also reproduces the appearance of display on a color
        television set of the period.
        There are 3 modes: basic, slideshow, and text. Normally  it  chooses  a
        mode  randomly,  but  you  can override with the -basic, -slideshow, or
        -text options.
        In basic mode a simulated user types in a Basic program and runs it.
        In slideshow mode it chooses a number of images from the  image  source
        you  configured  into XScreenSaver and displays them within the limita-
        tions of the Apple ][ display hardware. With only 6  available  colors,
        you can only make out the general shape of the pictures.
        In  text  mode it displays the output of a command or the contents of a
        file or URL (via the default xscreensaver-text(1) program, which can be
        overridden with -program).
        In  text  mode,  it is also a fully functional (if anachronistic) vt100
        terminal emulator.


        apple2 accepts the following options:
        -window Draw on a newly-created window.  This is the default.
        -root   Draw on the root window.
        -mono   If on a color display, pretend we're on a monochrome display.
                Install a private colormap for the window.
        -visual visual
                Specify which visual to use.  Legal values are the  name  of  a
                visual  class,  or the id number (decimal or hex) of a specific
        -basic  Choose basic mode
                Choose slideshow mode
        -text   Choose text mode
        -program sh-command
                In text mode, the command to run to generate the text  to  dis-
                play.  This option may be any string acceptable to /bin/sh. The
                program will be run at the end of a pipe,  and  any  characters
                that  it  prints to stdout will be printed on the Apple ][ dis-
                play. If the program exits, it will be launched again  after  3
                seconds.  Default: xscreensaver-text(1).
                In  text  mode,  apple2  emulates a vt100 terminal running on a
                40x24 uppercase-only screen.
                For example:
                     apple2 -text \
                            -program 'cat /usr/src/linux*/README | fold -sw40'
                     apple2 -text -program 'ping'
                     apple2 -text -program 'ps -e'
                     apple2 -text -program 'od -txCz -w7 /dev/urandom'
                     apple2 -text -program 'cat /dev/random'
                     apple2 -text -fast -program 'xemacs -nw -q -f life'
                     apple2 -text -fast \
                            -program 'xemacs -nw -q --eval "(hanoi 5)"'
                You can also use apple2 as an extremely lo-fi  replacement  for
                the xterm(1) and gnome-terminal(1) terminal emulators:
                     apple2 -text -fast -program tcsh
        -pty    In  -text  mode,  launch the sub-program under a pty so that it
                can address the screen directly.  This is the default.
        -pipe   In -text mode, launch the sub-program at the end of a pipe:  do
                not let it address the screen directly.
        -esc    When  the user types a key with the Alt or Meta keys held down,
                send an ESC character first.  This is the default.
        -meta   When Meta or Alt are held down, set the high bit on the charac-
                ter instead.
        -del    Swap Backspace and Delete.  This is the default.
        -bs     Do not swap Backspace and Delete.
        -fast   Normally,  characters  are  printed at the speed of an original
                Apple][ computer; however, when using this program as a  termi-
                nal  emulator,  the  novelty of those 300 baud characters might
                wear off.  You can use the -fast option to speed  things  up  a
        -fps    Display the current frame rate and CPU load.
        By  default,  apple2 allocates a pseudo-tty for the -text-mode sub-pro-
        cess to run under.  This has the desirable side effect that the program
        will be able to use ioctl(2) to fetch information about terminal param-
        eters and window size, which many programs (such as top(1)) need to run
        properly.  apple2  will also set the environment variable TERM to vt100
        in the child process.
        Any characters typed on the apple2 window will be passed along  to  the
        sub-process.  (Note that this only works when running in "window" mode,
        not when running in -root mode under xscreensaver.)
