put finger to keyboard and composed:

I'd say that 8112 is a YYWW date code.
It is a YYMM date code.
Then how do you account for the "32" in "235-8532K"?
It IS YYWW (that is year and week)
so....235-8532 means 1985, 32nd week. That is why the K is there...


I agree that it is YYWW, but I don't understand what you are saying the
reason
is that the "K" is there? Why is the "K" there?


weeK, to avoid any possible confusion to the date format used.


That's where I figured you were headed with the "K", but typically the YYWW date
code, as used on semiconductors for example, is used without a format indicator,
in fact IIRC some versions of the YYWW date code scramble the digits in one way
or another to obscure their meaning.

I wonder if the "K" might not have another meaning, such as a code to indicate
which of several factories the device was produced in? If that is the case, the
fact that "K" is the last letter in "week" might just be a coincidence.
