I just copied the email to a friend who was at CDC ad he says they were
from the CDC3100.

Any idea what the row of hole opposite the contacts were? Testing points?
But then

Hi Peter,
That is a stunning board, and in beautiful condition.
The square cubes are transformers, most likely some sort of pulse
transformer on the base of the transistor.
A multimeter will tell you in quick form.

Sure looks like Control Data, a major manufacturer of
mainframe computers in the 60's and 70's.
And, being all discrete transistors, that would likely be
late 60's.

Nope, those tiny urls still refer to URLs that we can’t open. As was suggested
before, these URLs are probably specific to your browser session.

Sorry guys about the unusable tera-URLs.
To reiterate, I have acquired this board and have trouble assigning it to a
particular computer manufacturer and type:
