[Pharo-users] [OT] RTalk

I found this http://www.jarober.com/blog/blogView?showComments=true&printTitle=IM_98:_Rta... ,about RTalk , that is not only smalltalk run on top of JVM but almost the entire environment.  The problem is that I cant seem to be able to find via google any site that contains the source code or something I could use ? Does anyone know if there is any official website for RTalk ? It looks quite promising and I would like to give it a try.
