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.
