the 640k barrier was a major pain in my butt for almost a decade. first we had expanded memory, then extended memory, both of which could only be used by some programs. then there were add-ons like qemm, which could remap physical ram into unused areas of the 384k add-on space. for a long time there, computers that had more unused rom space than others were more valuable to people like me who ran a bunch of memory-hungry apps. what a nightmare!

i should have gotten on the unix bandwagon from the beginning. at the time i just didn't know any better.
