thank you for your post
i stand corrected
the first use of the Motorola processor by dedicated computers only used 16 bits
of data path

not until the 68020 processor do we see the full 32 bits being used by the
programers

below is the first dedicated computer(module) to use a 68020 32 bit processor

the Mephisto Dallas,winner of the 1986 World Micro Computer Championship:
