It was identical except for the 9-160-05/06 board being a 9-160-FRM. That one was actually a different board altogether.

...and Setchell Carlson made an 19" B/W inverter-based TV (more like a video monitor) for aircraft use. Conrac was left holding the bag on it when S-C went under. 27.5VDC input, and two 75-ohm impedance UHF connectors for input. I've seen one, used in the "Admiral's Bird", a Convair twin-prop post-WWII bird they had at NAS Norfolk Operations. The one I saw was a ready spare, but I don't think the original ever got pulled from the aircraft.
