SimH will NOT run under DOS as it is right now, because of
memory (and -model) constraints. Under Win9x and up, it
uses Win32 mode.

FAQ: Does SimH run under DOS?
     No. SimH assumes various things about the system it is
     running on, and one of those assumptions the ability to
     allocate memory in large chunks, which is very hard to
     do under DOS without extra work. Various other issues
     exist as well. One day, it can be done, but not now.
