   They were never documented by the vendors, but back then (1995) when I   
   wrote my value tracking code analyzer as part of disassembler and   
   debugger I tested all code variants and found _some_ alias on +486.   
   sorry for I lost my handwritten notes on it due a water disaster.   
   Meanwhile sandpile.org show new usage of many opcodes, but there are   
   still a lot doubles left undocumented especially in the 0Fxx groups.
