+ *
+ * interrupt_vectors.s -- the interrupt handler jump table. 
+ *
+ *
+ * There are a total of 32 interrupt vector possible, however, only
+ *   11 of those are currently used (the others are reserved). The
+ *   order of vectors is as follows:
+ *
+ *     1. Boot Vector. Vector for power-on/reset.
+ *     2. Software Vector. Vector for handling the SI instruction (an
+ *          explicit interrupt caused by software).
+ *     3. Break Vector. Vector for handling the Break instruction.
+ *     4. Device 0 Vector. Service vector for device zero. 
+ *     5. Device 1 Vector. Service vector for device one. 
+ *     6. Device 2 Vector. Service vector for device two. 
+ *     7. Device 3 Vector. Service vector for device three. 
+ *     8. Device 4 Vector. Service vector for device four. 
+ *     9. Device 5 Vector. Service vector for device five. 
+ *    10. Device 6 Vector. Service vector for device six. 
+ *    11. Device 7 Vector. Service vector for device seven. 
+ *
+ *   The rest of the interrupt vectors are reserved for future use.
+ *
+ *
+ * Each jump table entry consists of the following two instructions:
+ *
+ *   jmp Label		; Label as appropriate
+ *   nop 		; implemented as or r0,r0,r0
+ *
+ *   The following labels are reserved for the vectors named above,
+ *   respectively:
+ *
+ *     _BOOTIVEC, _SOFTIVEC, _BRKIVEC, _DEV0IVEC, _DEV1IVEC, _DEV2IVEC,
+ *     _DEV3IVEC, _DEV4IVEC, _DEV5IVEC, _DEV6IVEC, _DEV7IVEC
+ *
+ *   28Apr05 (DJK) Added support for the overflow vector.
+ *
+ *   XXXXXXX (DJK) Modified for the MS2 target
+ *
+ *   09Jan04 (DJK) Modified internal I/O port definitions for the
+ *                   MS1-16-003.
+ *
+ *   10Oct01 (DJK) The memory map is finalized and the first 4K of address
+ *                   space is now reserved for memory-mapped I/O devices.
+ *                   (There is over 2K unused, reserved space in this area.)
+ *
+ *   26Sep01 (DJK) The memory map is changed and the device interrupts are
+ *                   now memory-mapped.
