Comments:
  - Real 16bit hardware or GT*O! :) :) <3 
  - db sound levels denote hardware quality (tm).
  - 2 Source files. One is smol and crufty (t-o.c). 
  - Second (t.c) has comments and spaces because not raised by savages.
  - It should work om SIMH, PiDP11, w11, $etc no problem but is untested.
