Today I attempted to upgrade my 2400c to what I thought would be 80 megs of ram . I had ordered 64 megs of ram from Memory X this summer and had just now gotten around to installing it. The install went well, however, upon restart the PowerBook only registered 48 megs of ram. As the ram was labeled 64 megs is it safe to assume I was ripped off or is there another logical explanation for this (ie some software or hardware limitation)? - Brad Lincoln
