I have done a fair amount of work with the DOS-73 board, and have
the following observations:
  1) If your application absolutely must run on a 512K machine, it
probably won't run on the DOS-73.  If you do a CHKDSK you will find
that somebody stole some of your memory.
  2) The mouse is Microsoft Compatible and the display is Hercules
compatible are statements that rank with "The check's in the mail"
and "I'll love you in the morning" for believability.  The Hercules
compatibility is restricted to only one page, and the mouse driver
does t support all commands.  This means that Framework cannot use
the good display stuff, but must run in dumb display mode.
GEMDraw cannot find the mouse.
  3) A lot of copy protection schemes work so well that you cannot
use the software at all on this baby.

Now the good stuff:
  1)) If you want a UNIX engine that will run some of the DOS
applications that you just can't live without, this is for you if
your applications will run.  I got someone to unlock my LEGAL copy
of Symphony so that it would stop checking for the specific floppy
controller.  Once that was done, it worked great.
