Side-tracking here, but I have a few K-series modules and I see at
  http://research.microsoft.com/~gbell/digital/timeline/1967-2.htm
they are described as having high noise immunity for use in industrial control
systems. Are these something like the discrete equivalent of HTL ICs? Anyone
know if there was a standard/common DEC processor built from them, or perhaps
an industrial version of such a processor?

DEC-heads might like these:

(I hadn't come across them before)
