Impressive!  If I understand correctly, SIMH was never meant for production
use, but rather designed for historical accuracy and preservation.
 Nevertheless, many people in the community have found that it fills a need,
and have taken the effort to investigate how the code can be adopted to
daily production use.  Kudos to everyone involved, especially Bob Supnik and
the other core SIMH contributors for making it all possible in the first
place.
