Said Jon:
" In a microcoded machine, the same hardware is used for every
microinstruction. In random logic, custom designed circuitry is used for
each special case."
Best way to get a handle on the distinction is to read up on the originator
of the concept, Maurice Wilkes:

The original paper:

"The Best Way to Design an Automatic Calculating Machine" (1951)
