None of this was really the case though; the Macintosh II shipped in early 1987 and was a fully 32-but system. People get confused about its support for 24-bit addressing, but with the ROM update that came out in 1988 with the introduction of the IIx (which was basically a II with 68030/68882 replacing the 68020/68881/MMU) it could even address up to 128MB of RAM.
