#60 Secondary Video Window

[kalpha]

Is it possible to have a second window emulating MDA/hercules monochrome output while primary window is CGA/EGA/VGA possible.
I saw something like dualmon.c is that for the above or was that for a pc with genuine (very) old style dual graphics card arrangement (i.e. MDA/Hercules with lpt port) + CGA/EGA ?
