Poor convergence? The mind boggles.

Oh, yes. The pickups had to be aligned. The "modern" system, in which
solid-state sensors are attached to a prism/beamsplitter was not

Registration on cameras. Convergence on monitors?

Did you have videcon colour cameras? First UK ones were plumbicon. Apart
from the ancient IO RCA ones used for tests.
