I've pdf'd half a dozen pages of the 360/40 development manual from IBM British
Labs at
Hursley UK, early/mid 60s. I wish I had more but these only survived because dad used
to bring home binders with these single-sided pages for us kids to draw on, and my
parents kept them. They may not even be from the same document, but it's just for
interest's sake.
