+<para>
+An alternative video screen device driver, which provides a 51
+column by 24 line display with upper and lower case character sets,
+can be incorporated into OS-9 with the command:
+<screen>
+GO51
+</screen>
+This command replaces the normal text screen driver with one that
+uses high resolution graphics to &quot;draw&quot; the characters. As there
+are fewer pixels (dots) per character in this mode more characters
+can be displayed on the screen, albeit with some loss of character
+definition.
+</para>
+<para>
+Note, however, that the use of a high resolution graphics page
+means that an extra 6K bytes will be needed in this mode. This
+extra memory requirement is not normally a problem but in memory-critical
+applications, such as the C and Pascal compilers, the user
+can simply avoid the use of GO51.
+</para>
+<para>
+This mode of display has a set of <emphasis>escape sequences</emphasis>
+(commands) to
+emulate commercial data terminals. In addition to the video screen
+driver, GO51 provides a new keyboard driver which features auto-repeat.
+The keyboard code allocation is the same as described in
+section 2.4.3 and Appendix D.
+</para>
+</refsect1>
+<refsect1>
+<title>The GO51 Display Functions</title>
+<para>
+Like the normal 32 by 16 video display functions described in
+Appendix C the 51 by 24 mode provides many built in facilities to
+control the display. These functions are activated by the use of
+the various escape sequences and control characters described below:

+The heart of your &make; Computer is an amazing device: the
+6809 microprocessor chip. This advanced microcomputer can run the
+kind of sophisticated software normally found only on much larger

+by the same people who designed the 6809 microcomputer, together
+they provide an extremely efficient and powerful combination.

+The foundation of a computer's software system is its
+<emphasis>Operating System</emphasis> or "OS". It is the master control
+program that interfaces all other software to the system's hardware. Some
+of the things it must do are performing input and output operations,
+coordinating memory use, and many other "housekeeping" functions. All
+other software - programming languages, applications programs, etc. -
+live in your computer's memory along with the OS and depend on it to
+communicate with you using the keyboard and display and to store and
+retrieve data on disks, etc. Because virtually all other software relies
+on the OS, your computer's performance depends on the capabilities and
+efficiency of its OS.

+OS-9's overall structure was based on the famous UNIX<footnote id="unixdesc">

+operating system, which has been widely acclaimed as the operating
+system of the future because of its versatility, logical structure,
+and friendly user commands. The OS-9 family of advanced software is
+not only more powerful than most other microcomputer scftware - it
+is also much easier to learn and use.

+If you don't know what some of these thing mean yet - don't
+worry. As you explore OS-9 you'll soon learn how they enhance the
+capability of your &make; Computer and make it so much easier to use
+in almost any application.
+</para>
+<para>
+OS-9 has many commands and functions - definitely more than
+you can learn in an evening! The best way to become an OS-9 expert
+is to study this manual carefully, section-by-section, taking tire
+to try out each command or function. Because many functions affect
+others, you'll find this manual extensively cross-referenced so you
+can skip ahead to help you understand a new topic. Taking the time
+to study this book will certainly increase your knowledge and
+enjoyment of OS-9.

+But if you can't wait, at least read the rest of this chapter,
+scan the command descriptions in Chapter 7, and have fun
+experimenting!
