Which proves once again that a shitty design beats a good one
if it`s released first.
Everybody was yapping about the 640K barrier. I was more concerned
with the 64K barrier. I remember manually normalizing pointers
everywhere, and if I wanted to work with a large arrays of structures
I`d copy individual structures to a work area byte by byte so I
didn`t get bitten by segment wrap-around in the middle of a structure.
As the joke goes, aren`t you glad the iAPX432 died out?
Otherwise a truly horrible Intel architecture might have
taken over the world.
