I have uploaded more photos of my TU10M (it's a master with the TM
backplane installed). I also updated the design of the file listing pages
on my site to make it easier for people to find things. One of the images
shows it has the RSX-11M tape loaded.
I have been cleaning the cables, having fun on a sunny afternoon.

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.)

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.
