[Coco] modifiying a coco 2 power supply

[didier derny]

The coco II  I received is  110V 60Hz

I guess I can disconnect the transformer and 
feed a dc signal after the diode bridge ?

Hi,

I tried but no success...

I don’t have any image on tv (connected to the antenna) No idea if the coco
2 is broken or if my tv is unable to process the signal

With the oscilloscope I've not been a able to find a composite signal Inside
the modulator...

Any idea ?

Thanks

Hey....

I did mine by tapping into the feeds that go directly to the rf
modulator....

A couple of shielded wires soldered on to the pins and 2 rca jacks on the
rear of the case (audio/video)

Works fine... No extra components needed (PAL machine)...

Hi

Is there an easy way to get a video composite signal on this machine ?

I guess a video composite signal or something approaching should be found
Somewhere near the modulator or inside the modulator ?


Thanks
