You'd actually call the MC14500 a processor? Golly, can't add, no
program counter, basically a 1 bit logic unit.
Speaking of 1 bit oddities, does anyone on the list collect PDP-14s
or even PDP-16s? Just curious.

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.
