Asus and Microsoft's new handheld gaming consoles are two of the newer additions to Luke's arsenal. "They are just monsters," he said. "It really is like having an Xbox in your hands." He finds them more comfortable to use than other handhelds because they have console-style controller grips, "so my boomer hands don’t get tired playing on it."
DOS 1.x (1981) had no explicit memory management support. It was designed to run primarily on machines with 64K RAM or less, or not too much more (the original PC could not have more than 64K RAM on the system board, although RAM expansion boards did exist). A COM program could easily access (almost) 64K memory when loaded, and many programs didn’t rely on even having that much. In fact the early PCs often only had 64K or 48K RAM installed. But the times were rapidly changing.
