The 8I was a TTL cpu and was a lot of DEC cards interconnected to make
a minicomputer. There is no one board, or 15, in an 8I that could be
called the CPU or even the core processor. The 8E did reduce that to
three cards timing, major registers, major registers control.
The dividing line is level of integration. The F14 CADC basically put
those three 8E card into one ot two chips.

Microprocessor is a functional name ie: what it do, not what it are.
So in most senses microcomputer and microprocessor are one and the same
but not always interchangeable.
