Responding to the following:
 
"Also note that the address registers can be used to store data. I
    believe Microsoft did so with one of their Amiga products? Something
    like storing data in the top byte of an address register, on the
    assumption that only the low 24 bits are used for addressing
    purposes."
 
Apple also did this with the original MacOS. Of course, this was in the day
of 128K machines. But the transition has been rather smooth since Apple
warned developers about 32-bitness back in 1986, so most programs are
"32-bit clean".
