accomplished by attaching the 5- pin plug into the socket on the
side of the Atari 800 . This is shown in Illustration 1-4.
Regardless
of whether a television set or a monitor is being
connected to the Atari, several different modes of display are
available.
One of these is the monochromatic text mode. This
mode is used to display one color plus white (ex. black and
white, blue and white, etc.). In the monochromatic text mode ,
the screen is divided into 24 lines of 40 characters each. Two
other modes are available for displaying text in up to four
different colors. Other modes are available for displaying
graphics. These
will be discussed in detail in Chapter 9.
