Ancient transistor ?computer board (Peter Van Peborgh)

[Peter Van Peborgh]

Guys,

I now know it is an early CDC board. IT had C*NT*OLDATA on the reverse - how
I missed that must be attributed to old age. (Thanks Doug)

Here are shots of the back: https://photos.app.goo.gl/UPozyBB3zp7XYcP79

Any idea what the row of hole opposite the contacts were? Testing points?
But then why holes and not short pillars? Some are labelled on both sides.

Continuing in hope,
