Most people simply didn't know better.  I was working with VAX/VMS on a
VAX 11/780 long before I ever touched a "PC" and knew better.

I remember "overlays" on a Date General Nova, using a head per track
disk (all of 256 or 512KB).  There was also a memory mapping board for
the DG Eclipse that allowed much more than the base 32K 16 bit words. 
Of course, in the PC world, there was everybody's favourite, the LIM
boards, which provided a more or less standard method of memory mapping.
