CRTFORPX.INF.txt

Info for a similar, but homegrown project, intended for an IBM monochrome monitor. The original file is called ''crtforpx.lbr'' and was found at http://cerealport.homeip.net/cereal/px8/. The file was corrupt or made with a unknown version of the LBR compression program, so the included drivers are lost.
