   Very interesting about the computer.  If you learn more, by all means post   
   it.   
      
   You can find documentation on NewDOS 2.1 (a.k.a. NewDOS+) at www.trs-80.com.   
   Most of the commands come out of the TRSDOS manual, which is also there.   
   Mostly, Apparat documented the changes they made to TRSDOS 2.1 to make it   
   work, plus the utilities they added.
