 * DESCRIPTION:
 * Translates PS2 keyboard MAKE/BREAK codes into ASCII.
 * This file creates no executable code, it merely stores a couple of large
 * lookup tables.
 *
 * NOTE this lookup table mechanism favours speed over memory usage - the table
 * is sparsely populated and wasteful of code space.  A more efficient memory
 * solution would use a compact table and a search algorithm - but that would
 * be slower.
 *
 * LAST MODIFIED BY:   $Author$
