Motorola may make that claim now.  They certainly did not when the 68k 
was released, nor to they make that claim in the MC68000 Microprocessor
User's manual.  The first MC68000 that had internal 32 bit architecture
was the MC68EC000 which I believe was released ca. 1991.  The EC has very 
signifcantly different internal architecture from the MC68000.
