CGACAL Description

The CGACAL application was designed to be a small program was created for owners of CGA cards and monitors (and emulator authors) who want to adjust their hardware / software so as to get the "proper" authentic CGA palette.If running this program under Windows just to see what it does, make sure you hit ALT-ENTER so it is running fullscreen before you answer the initial hardware compatibility question. Otherwise the colors will be wrong, as it will be running in a window and using the incorrect Windows palette (instead of the VGA card's BIOS colors). Color #6 Is BrownTo anyone who looks at the CGA pinout, it appears that the logical color for #6 would be dark yellow instead of the much darker brown we are familiar with. But CGA monitors display brown, not dark yellow. How? It turns out that the monitor does the translation, and IBM intentionally added logic in the monitor to decrease the green component on color #6 so that it would appear brown.
