Fact is, I have seen facilities (by photograph though) in Japan where IBM
manufactured
core planes, by hand. The pictures probably came from the early '60s but,
they clearly
show ladies sitting at circuit board mounting tables, large magnifying
glasses with
integral florescent lamps, and core plane frames mounted in circuit board
holders for
easy working. I am sure that machines were constructed but, I am also sure
that some
of the earlier work was done by hand.
