Acorn - Genlock Modifications to the BBC Microcomputer

A Genlock was a device for synchronising two different video signals, or a video signal with a computer or audio signal, allowing video and computer graphics to be mixed.  This manual instructs the user on the modifications required to apply one to a BBC Micro.

From the introduction:

'This manual contains the information necessary to modify the British Broadcasting Corporation Microcomputer so that the RGB and monochrome outputs may be made line and field synchronous with an external reference feed of composite synchronising pulses. The addition of the Genlock board allows monochrome synchronisation only.
