       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 limitations 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 visual.

       -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 display. 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 ][
               display. 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

               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 character 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 terminal 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-process to run under.
       This has the desirable side effect that the program will be able to use ioctl(2) to  fetch
       information  about  terminal  parameters  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


       DISPLAY to get the default host and display number.

               to  get  the name of a resource file that overrides the global resources stored in
               the RESOURCE_MANAGER property.

       TERM    to inform the sub-process of the type of terminal emulation.


       Notable X resources supported include  the  following  which  correspond  to  standard  TV
       controls:  analogTVTint,  analogTVColor,  analogTVBrightness,  and  analogTVContrast which
       correspond to standard TV controls. They range from 0 to 100,except for tint which  is  an
       angle between -180 and +180.
