SPIM is pretty useful.  I used it in an intro to assembly class here at the
UW.  The binaries ARE available on sunsite under emulators.  The xspim has
a nice interface.  It allows you to step through code.  The emulator reads
in the source at text levels and also takes the a.out files of a compiler.
