I've been surprised at how little I can find about broadcast television cameras on the Internet. Compared to the resources available for cine cameras, there's relatively few forums, details or photos available. I know the cameras were extremely expensive and niche technology, but I would think there would be more interest.
It's hard to tell from a quick Google search if this camera ever even really existed. Seems like if it did, maybe it was only produced for the US military?
I'd be interested too if anyone has any more info...
The Telemite might have been tiny, but recording units were a bit larger: https://en.wikipedia.org/wiki/Ampex#Quadruplex
