NAME
     apple2 - Apple ][ display emulator

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

DESCRIPTION
     The apple2 program simulates an original Apple ][ Plus computer in all  its
     1979 glory. It also reproduces the appearance of display on a color televi-
     sion 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 op-
     tions.

     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(6) program, which can be overrid-
     den with --program).

     In text mode, it is also a fully functional (if anachronistic) vt100 termi-
     nal emulator.

OPTIONS
     apple2 accepts the following options:

     --window
	     Draw on a newly-created window.  This is the default.

     --root  Draw on the root window.

     --window-id number
	     Draw on the specified window.

     --mono  If on a color display, pretend we're on a monochrome display.

     --install
	     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

     --slideshow
	     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(6).

	     In text mode, apple2 emulates a vt100 terminal running on	a  40x24
	     uppercase-only screen.

	     For example:

	       apple2 --text --program 'ping apple.com'
	       apple2 --text --program 'ps -e'
	       apple2 --text --program 'od -txCz -w7 /dev/urandom'
	       apple2 --text --program 'cat /dev/random'
	       apple2 --text --fast --program 'emacs -nw -q -f life'
	       apple2 --text --fast \
		      --program 'emacs -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  Ap-
	     ple][ computer; however, when using this program as a terminal emu-
	     lator,  the  novelty  of  those 300 baud characters might wear off.
	     You can use the --fast option to speed things up a bit.

     --fps   Display the current frame rate and CPU load.

TERMINAL EMULATION
     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. ap-
     ple2  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.)

ENVIRONMENT
     DISPLAY
	     to get the default host and display number.

     XENVIRONMENT
	     to get the name of a resource file that overrides	the  global  re-
	     sources stored in the RESOURCE_MANAGER property.

     XSCREENSAVER_WINDOW
	     The window ID to use with --root.

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

X RESOURCES
     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.
