C.1 INTRODUCTION
This appendix describes the Compaq keyboard that is included as standard with the system unit.
The keyboard complies with the industry-standard classification of an “enhanced keyboard” and
includes a separate cursor control key cluster, twelve “function” keys, and enhanced
programmability for additional functions.
This appendix covers the following keyboard types (some of which may be available only as an
option):
♦ The Windows-version keyboard includes three additional keys for specific support of the
Windows operating system.
♦ The Erase-Ease keyboard features a split spacebar that can be user-programmed to provide
easy access to the backspace function or set to operate as the normal spacebar.
♦ The scanner keyboard includes a built-in document scanner for scanning loose-leaf
hardcopy.
NOTE:
This appendix discusses only the keyboard unit. The keyboard interface is a
function of the system unit and is discussed in Chapter 5, Input/Output Interfaces.
Topics covered in this appendix include the following:
♦ Keystroke processing (C.2) page C-2
♦ Scanner description (C.3) page C-14
