     BOMBS
     -----
       2     :     BUS ERROR - This occurs when a program tries to access a
                   non-existent location in memory.

       3     :     ADDRESS ERROR - This occurs when trying to access a word,
                   long-word or 68000 instruction from an odd-numbered
                   memory location.

       4     :     ILLEGAL INSTRUCTION - This occurs when the CPU tries to
                   execute from a memory location that does NOT contain a
                   valid 68000 instruction.

       5     :     ZERO DIVIDE - A number was divided by zero.

       6     :     CHK INSTRUCTION - 6 bombs is one possible result of a
                   68000 "chk" instruction; the other is the continuation
                   of any executing program. It is up to a program to replace
                   this vector with some other number.

       7     :     TRAPV INSTRUCTION - 7 bombs will occur if a 68000 "trapv"
                   instruction is executed and an overflow in an arithmetic
                   operation occurs. This vector can also be changed by a
                   program to warn users that an overflow has occurred.

       8     :     PRIVILEGE VIOLATION - Occurs when "supervisory"
                   instructions are attempted in "user" mode. 

       9     :     TRACE - The 68000 can be configured to go to a specific
                   address after every machine instruction is executed. If
                   this address does NOT exist you will get 9 bombs.

      24     :     SPURIOUS INTERRUPT - This is when a bus error occurs
                   during a system interrupt.
