Some more information for you: The Diagnostic Engine Interpreter opcode 
interpreter (the bit that picks a handler based on the opcode value) is at 
L-682. This is basically the same code as in the STBM and probably BOOT.

I should probably see about souping up my disassembler. Mine can do symbol 
substitution for memory locations (in A-, M-, and I- memory), but it's a 
rather underused feature. I also have some code to re-disassemble a file to 
regenerate the disassembly based on new symbol table entries while leaving 
comments undisturbed. I should be able to rig that to operate on a region 
instead...
