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,
peter

Ah, the missing letters are covered by solder!

Yes, for sure. The way they are made so close to the edge, you can just clip a scope
probe to them for testing.
