  The 640k limit was invented by IBM; Microsoft adapted an earlier 
operating system to IBM's hardware.  

  At that time (1980) the Apple II was coin of the home computer realm, 
and a Really Big one had 64 kilobytes of memory.

  So IBM's people multiplied that by 10, and (at the time) it was
Amazingly Big.  Little did anyone know.  BTW, 4 years later the first Mac 
had (drum roll) 64 kb of memory!
