	 Tandy CM-11 monitor is a EGA like monitor, and DESKMATE has made full

   detected as CGA. Does anybody know how to set graphics mode for CM-11?

The answer to the question is that the CM-11 is not an EGA monitor, it is
a CGA monitor that supports 16 colours at CGA resolutions (depending on the
machine some tandy's had 640x200x16 others didn't). The resolutions that 
support more than CGA colours 320x200x16, 640x200x4, 640x200x16 are special
tandy graphics. These modes are supported by a number of software makers, but
I don't think I've seen a Turbo Pascal driver. If you want to write your own,
the assembly language methods were documented in one of the Tandy programmer
references guides, though the exact name escapes me.
