- Jerry is right, DR3INT seems to be a word which is modified
- by the contents of the remainder of the table. The two
- BR instructions are what get moved into it. I would suspect
- that there must be code which initializes DR3INT, otherwise
- the first time through this code, the processor would halt.
- Also, the BR 20$+2 appears to be wrong, as Jerry stated, it
- appears that it should be BR 20$+4.
