Did the PDP14 (or any machine of that era) ever use hand-threaded (by the end user) core

Do you mean DEC machine?
I don?t know any. Certainly not any PDP-11; those
used solid state
ROMs, or in the early boot ROM cards, diode arrays.
I want to make sure it wasn't in use before I double-down on calling
shennanigans on "Joe" in this thread:

As far as I know, machines of that era used cores that were so small the
DEC hired master seamstresses (myth?) to make them. It's certainly not
something that would be done in the field by John Q. Programmer.
If I'm wrong, I'll happily admit it, but it just doesn't sound reasonable.
Thanks!
