I just noticed the 7 second time delay.
I don't remember that version, but I do remember all too well the version of rollers that sat between the tape machines on the 1st floor of the Broadcast Center in New York.
We would switch a show on the line to a particular tape machine. The tape from that machine would then go through the rollers over to the next for playback. The playback tape machine would be routed to the Mon 3 bus and out to air. We would "normal" during a commercial break. I would do large portions of "Nightwatch" that way from Studio 44 whenever we had a live guest or took live phone calls from viewers. That was the first of the overnight news and went on the air at 2am - 6am weekdays.
