There are so many aspects one can bring up. Some will show strong
similarities, and others that make them look totally different.
My point here was simply that controllers sitting in their own cabinets,
made out of lots of small flip chips can be seen both on KA-10, KI-10,
PDP-8 and PDP-11 systems from the late 60s, early 70s. Rather similar in
concept. Usually also with lots of blinkenlights to show various
information about the controller. (You just gotta love the "MAGIC" lamp
of the KI-10.)
(And I wouldn't be surprised to hear that the PDP-15 were similar, but
since I have never seen one of those myself, I can't comment on them.)

I have played a little with KA-10 and KI-10. And
yes, there are
similarities.
KA is built out of R/S/B series negative logic modules, which have
single-sided edge connectors.
KI was built with TTL (M series postive logic) as was the PDP-8I/L/E,
PDP-12, PDP-15, and PDP-11 and
have double-sided edge connectors with backplaces that have .025
wire-wrap posts.
