You'd actually call the MC14500 a processor? Golly, can't add, no
program counter, basically a 1 bit logic unit.
How does one implement a 1-bit program counter? Seems to me being able
to distinguish between two program instructions doesn't seem *all* that
useful. 8-)

How many MPUs had no provision for interrupts? The
Rockwell PPS-8 is
one that comes to mind. What's surprising is that it was used in the
Diablo dot-matrix printer--something you'd think that was a very good
candidate for an interrupt-driven architecture.
I don't think Motorola's 1
bit processer had that feature.
