Link-NEC 100 Television Camera

This Link 100 is the one in the museum collection and as you can see it is a few bits short.
If you can help please contact me, Thanks

The small cover behind the lens is missing.
The lens does not belong to this camera.
At the rear, near the Link100 logo you can just see an edge connector were the interface unit attaches. Inside a card is missing, see later picture.
