+ *               bits 1-0  second vendor char in compressed ASCII (bits 4-3)

+ *                bits 4-0  third vendor char in compressed ASCII
+ * product byte 0 bits 7-4  first hex digit of product number
+ *               bits 3-0  second hex digit of product number
+ *        byte 1 bits 7-4  third hex digit of product number
+ *               bits 3-0  hex digit of revision level
+ *
+ * ISA IDs are always expressed in little-endian order, even though
+ * the underlying "meaning" is big-endian.
