+<sect1>Direct console I/O<p>
+
+The <tt/atari5200/ target uses Antic mode 6 (BASIC mode 1) for the console
+screen by default. There are four colors available:
+
+<itemize>
+<item><tt/COLOR_WHITE/
+<item><tt/COLOR_RED/
+<item><tt/COLOR_GREEN/
+<item><tt/COLOR_BLACK/
+</itemize>
+
+Note that the <tt/COLOR_GREEN/ and <tt/COLOR_RED/ colors aren't
+exactly the same colors as the ones with the same name on the
+<tt/atari/ target.
+They are the colors which are available as <tt/COLOR_LIGHTGREEN/
+and <tt/COLOR_LIGHTRED/ there.
+
+One can set the color shadow registers directly with other colors.
+Then the color defines from above will just become placeholders. In
+this scenario it might be more convenient to use index values (0..3)
+instead of the color defines. The index values specify which of the
+system shadow color registers (<tt/COLOR0/ .. <tt/COLOR3/) to use.
+
+The default console screen has a layout of 20x24 characters. An
+alternative layout, 20x12, Antic mode 7, BASIC mode 2, is provided in
+the file <tt/atari5200-conioscreen-20x12.o/.
