Merriam Webster and the OED gives the first published use in 1967

The 1700 would fit into that in at least one of its incarnations.  The
160A would not, as it went out of production in 1965, for example.

Sometimes words can be misleading.  The word "microcomputer" when
initially used, did not mean what we think of today--that of a certain
level of integration of an IC that includes most of the component parts
of a computer.

AES used this same term much earlier for "a computer than can be
microprogrammed" as implemented in a cage of of cards.
