 * This file defines the values used in the Sun-2 LED's by the monitor.
 *
 * Unix might use other values, we don't define them here (yet?).
 *
 * It is desirable that these values match those used by Manufacturing's
 * diagnostic PROMs.
 *
 * Values with the high-order bit set are defined in sign-extended form,
 * so our assembler will assemble them into 'moveq' instructions.
