Thank you for this, I never knew how this worked. My experience as an IBM 360 (USC-ECL) operator was brief and I never got into the nuts and bolts. I vaguely recall, as a teen, taking a tour of a DEC-10 shop in about 1970 in Portland. Their printer played "Anchors Aweigh" and I never knew how. But now I wonder - does this mean they had an IBM 1403 connected to a DEC 10 somehow?
