Q. Did you ever say, as has been widely circulated on
the Internet, "640K [of RAM] ought to be enough for anybody?"

No! That makes me so mad I can't believe it! Do you
realize the pain the industry went through while the
IBM PC was limited to 640K? The machine was going to be
512K at one point, and we kept pushing it up.
I never said that statement?I said the opposite of that.
