No it doesn't.  The Intel chips force you to address off a segment
pointer, which the 68000 doesn't.  You could, however, write a 68000
compiler which uses one register for a data segment pointer and reference
all data off the register.  The 68000 just gives you the choice.  If amiga
OS had been designed with that sort of thing in mind, then all programs
would be relocatable during runtime.  (note, this isn't a flame)  Personally,
I'll stick with the chip I'm using now.  (though a 68030 would be nice)
