My big Mac has UHF coded input, composite video input and no seperate RGB inputs. (Not true actually, there's an S-Video port, but as far as I know it is not possible to wire a plug directly from RGB to S-Video.) My greenscreen monitor also connects to the composite video signal. My Sam produces no composite video output signal if the 12V is not present. Without it my Sam is not functional to any useful extent. And if I bought a new PSU then Format wouldn't guarantee the 12V line? Boy, am I glad I bought those Greenweld PSUs as soon as I did.
