David,

Thanks for speculating about how the extra output on the colour bar generator might be used, but Rich has subsequently given us a more definitive answer.



Rich,

I have looked at the output from the extra socket on my oscilloscope and it certainly appears to be sync pulses only. The vertical pulses have an amplitude of about 5 volts and the horizontal ones much less, but as you say enough to act as a trigger signal.

I would very much like to have a copy of the service manual and will send you a PM.


Thanks and best regards,

Richard
