hi there how are you doing ? an crazy idea. if thr ascci chart off the keyboard driver. keyboard.sys. was altered. then ascii code 10 plus ascii code 10 or chr$(10) would deliver 20 of ascii code 20. since math is a language. a more convient ascci code set to calculate with. could been thinging off. and therefor . no hardware alernation is required. just load an imaginairy different keybaord ascci set or font type. to perform the correction between hex and dec.
