Your concerns over 386 vs 68030 are somewhat misplaced. It's Intel that is
behind. The 68020 has been out so long that with the current 386 hype
people forget that the comparison is between the 68020 and the almost as
powerful 80386. True the 386 has an MMU and the 020 doesn't but who is
using the protected mode of the 286 let alone the 386. 680xx programmers
have been writing 32 bit software for years with the same architecture.
Intel cpu programmers now have a machine with new registers and
instructions that allows them to finally start writing 32 bit code. As a
side benefit it allows them to run their old 8086, 80286 code as well. In
the MSDOS market Intel is king and due to SW mass is unlikely to be
deposed. In the industrial, workstation, and Unix markets the 68000, and
now the 68020 have an overwhelming lead. Nobody used an 80286 because of
the 64K segments which forced Unix back to PDP-11 modes of operation.
Reading electronics magazines or attending trade shows all you see is VME
bus HW. Multibus I and II are conspicuous by their absence. For quite a
long time now 680×0 and VME bus have been the only 32 bit game in town.
Now that Intel finally has a 32 bit cpu the only 80386 machines I've seen
so far are designed as somewhat faster 80286's which are in turn used as
fast 8086's.
