600 composite color problem

Yes, there is color on the startup screen (background is purple).  Have you tested the monitor with anything else to see if it's color is working correctly?  Also, are you sure the monitor can handle PAL?

Same thing happens with my PAL A600. Even though Commodore monitors support NTSC and PAL display modes, I think their internal composite interface is hardwired to either NTSC or PAL. It should be fine if you hook it up via the RGB port.

That makes sense.  The monitor can handle the frequency otherwise the screen would be rolling or not displayed, but doesn't know about the different color encoding.  And, since small box Amigas don't change color encoding when you switch from PAL to NTSC (just frequency).

(The bad part for the MigaMan is IIRC, the 1802 doesn't have RGB...)

In addition to the genlock, there were also chroma/luma boxes available.  I have one from Prevue here.  (Or, of course you can build one...)
