BBC Micro Computer Genlock Interface Board
This was removed from a non working BBC model B so untested
Looking at the BBC logo on the board it may be an internal BBC Television interface made for injecting the BBC video output into the TV Video (RF) signal.
The video socket attached to the board was fitted to the back of the BBC Micro, presumably to inject the TV signal and the output would have been from the combined signal through the standard video out.
One of the small satellite boards replaced the 16mhz crystal on the Motherboard.
The board with 2 LEDs was attached to the keyboard so that it could be seen through the edge of the perspex key strip.
I don't have any further information so sold as seen.
