simcga for DOS-73?

[Yong Ren]

	The DOS-73 card on Unix-PC generally works ok for Hercules graphics,
certainly it will be better if some CGA program can run on it. I tried the
public domain program SIMCGA for ibmpc, I believe it works, except the 
screen size is wrong. I am not familiar with ibmpc so I don't know how
to patch the program. Anyone out there has any ideas? Or maybe you found
another good way of doing it long ago?
