A couple of years ago, I did most of the work to 'port' the MLRISC sources 
to MLton; essentially, eliminating the SML/NJ extensions.  I reported a 
little on the experience at:
   http://mlton.org/pipermail/mlton/2004-February/025040.html

MLRISC has been mostly stable in the meantime, so it wouldn't be difficult 
to update them and make them available.  I started porting MLRISC with the 
vague notion of attempting to use it for MLton's backend, but I found that 
the documentation on MLRISC leaves much to be desired in terms of actually 
using it.  There is also some complication using MLRISC with SML/NJ's 
compilation manager (CM), which was never entirely clear how to resolve.

So, while I could point you to some Standard ML sanitized code for MLRISC, 
I'm afraid that I can't offer any advice on MLRISC itself.
