WWC 1000 Keyboards
Introduction
The WWC 1000 wrist computer has a configurable 27-key keyboard. By combining
keystrokes, the keyboard can emulate the full IBM-PC XT keyboard.
This appendix provides the standard keyboard definitions and indicates how key codes are
produced on the WWC 1000 wrist computer.
Keyboard Operation
On a PC, each key generates a scan code. The character code generated by a given key is
determined by the scan code and the current keyboard state: unshifted, shifted, control,
function, left shift, or right shift. The scan code generated by each key is constant,
independent of the keyboard state.
The WWC 1000 keyboard emulates the full PC/XT keyboard using one or more modifier
keys in sequence, followed by a character key. The modifier keys are:
Function (FUNC)
Shift
Control (CTRL)
Left Shift
Right Shift
The remaining keys (a through z, 0 through 9, special characters) are called “character keys.”
