Math Question: I posted the original message bout a week ago. All of those multiply routines are great, but I only need to multiply 8 bit numbers. Wouldn't it be faster for me to use an 8 bit routine? One more thing... Where exactly does USGARD relocate a prog, and can someone explain HOW it does it? (I know why, but want to know how...) One more thing... Did anyone ever determine how the screen is done on the TI-86?
