Hi, again, Win:
Notice also the magnified circuit at the top of the circle? That's what
it looks like, inside each "tin can" ... on the little "chips" inside
...
See:
http://www-03.ibm.com/ibm/history/exhibits/endicott/endicott-chronology/196…
and on that page, about half-way down, you can read about "Solid Logic
Technology (SLT)" -- that's what IBM called this stuff ...
And on the same page, search for "SDD" and "SMD" (as seen in the
picture) -- that stands for "System Development Division" and "System
Manufacturing Division", respectively.
Hope that helps,
Mark S. Waterbury

Any of you old timers (or otherwise) know what these components were and
what they might have been used for? A keepsake from my wife's
grandfather's career with IBM. I'm guessing 1960s vintage, give or take.
