Almost all Imp compilers either have an option to output a source listing which includes the
generated assembly language, or they have an external program which takes an object file and
a source or listing file and merges a disassembly of the object file with the original source.

Unfortunately not all have been preserved in source form, but I've attempted to collect all
that do in this directory.  Where sources were not available I've included binaries which
may work with some luck and effort in an emulator.
