A stable version of ciforth for the riscv under linux is available   
      
   https://github.com/albertvanderhorst/ciforth/releases/edit/CVS_REL-5-5-0   
      
   Altogether this is the 7th compatible 5.5.1 version for different os's etc.   
      
   It comes with the 4 documentation files, and one executable and one library.   
   The PostScript file has the short content index, long content index, glossary   
   index,   
   forth word index and concept index.   
      
   Also source of the documentation and for the executable.   
      
   As the riscv is of interest specially for the SBC community, for   
   control experiments, like the ARM versions, you can hack around   
   in the io.   
   For example I managed to have 31.5 kbaud uart midi from the DongShe board   
   and played the Fig leaf rag via my keyboard.   
   (This was running manx, a substantial program.).   
   As long as you are root, you can do everything that you can find   
   documentation for.   
      
   The other board I have been able to test was the OrangePI RV2,   
   but only at the Forth level. The documentation hunt is going on.
