>From what I remember from investigating this many years ago the US QL's do output a NTSC composite signal but it is not "proper" and this is why most monitors will show monochrome. Further adding to the confusion, any manual I have ever seen for US QL's doesn't show the output as being NTSC, it was always labeled PAL and since the signal wasn't quite "right" and didn't display correctly it got assumed that it was a PAL signal even though it is NTSC (well, almost). If you connect a PAL video signal into a NTSC monitor you will see a monochrome picture (assuming the monitor can sync to the slightly different scan rates). It's been awhile and I'd have to haul out an old QL and a 'scope to verify it but I think the composite signal had all the components it was just output at the wrong levels and most monitors can't tolerate the signal being that far out of spec. Can you get a color display using a television set connected to the RF modulator? If so you might have better luck connecting a composite monitor to the composite input pin on the modulator and disconnecting the modulator if you don't use it. I seem to recall the signal was a little closer to "proper" here than it was at the DIN-8 jack on the back. -- John Impellizzeri mailto:[EMAIL PROTECTED]
