The retro-computing guys - those who are fans of the MC6800 and MC6809 
microprocessors anyway, anyway, seem to be getting a rather good semi-
interactive disassembler up and running. So far it understands 
executables that run under FLEX, FLEX09 for both 6800 and 6809 and under 
UniFlex and OS9/level 1 and 2 on a 6809 and can automatically detect 
which OS the binary was compiled for. This is quite impressive, since all 
four OSen have very different API call structures despite FLEX09,UniFlex 
and OS/9 all running on the same chip.
