Look at the way graphics memory for the Bridgecard is arranged. It's addressed in three different locations, and in each one, the same memory is organized differently. I can easily imagine that a simple system can be devised to make the same region of memory look both pixel-packed and bit plane'd. Then, both the graphics.library and the 34020 would be happy. -- First comes the logo: C H E C K P O I N T T E C H N O L O G I E S / / \\ / / Then, the disclaimer: All expressed opinions are, indeed, opinions. \ / o Now for the witty part: I'm pink, therefore, I'm spam! \/
