We have several IBM PC's in our group equipped with Everex Graphics Edge 
Color/Monochrome boards.  We bought them because they claim to be compatible 
with IBM mono, IBM color, and Hercules software.  I have run Framework 
in Hercules mode on an IBM direct drive monochrome monitor with 
excellent results.  The board operates with "IBM" color software 
driving a Taxan RGB monitor.  Everex supplies a BASIC program that 
demonstrates 640 X 200 resolution in 16 colors.  We have also used it to 
drive an Amdek 300 composite monochrome monitor in either color or 
monochrome mode.  The Amdek horizontal hold and vertical height controls 
must be readjusted when switching between modes.  The Amdek monitor 
did not work properly in Hercules mode for unknown reasons.  The manual 
indicates 16 level grey scale display is possible on a composite 
monochrome monitor driven in color mode, but we have not verified this.
